Full Text FIELD OF THE INVENTION
The present invention relates to a mounting structure for a fuel pump
accommodated in a fuel tank of a vehicle engine and a vehicle installing the fuel
pump mounting structure.
BACKGROUND OF INVENTION
A fuel supply device disposed within a saddle type fuel tank that straddles a body
frame is disclosed in Japanese Patent Application Publication No. 2002-106440. A
fuel pump mounting structure described in Japanese Patent Application
Publication No. 2002-106440 has an opening in a surface located inside of the
saddle type fuel tank. A base plate closes the opening. The fuel pump is
disposed in an inner space of the tank and mounted such that an axis of the fuel
pump extends generally parallel to the base plate. That is, the fuel, pump extends
along the side surface where the base plate is attached. A filter is doupled with a
suction side located at an end portion of the fuel pump, wherein the end portion
extends along the axis of the fuel pump.
However, in the fuel pump mounting structure disclosed in Patent Application
Publication No. 2002-106440, the fuel pump is cantilevered against the base
plate. That is, the fuel pump is mounted such that an end of the fuel pump is
affixed to the base plate, while the other end is not affixed to anything so as to
be a free end. Further, the other end elongates along the longitudinal axis and
the filter is coupled with the other end. Because of this construction, a moment
of the cantilever structure (external force pressing the fuel pump and the filter)


against the base plate, which is a mounting plate for the fuel pump, can be
large. A firm mounting plate, thus, is necessary to support the fuel pump under a
stable condition against the moment. Therefore, the mounting plate can be
large, and fixing means for fixing the mounting plate to a tank wall, such as
bolts, need to be more strengthened. The fixing means cause increase of such
bolts in number and increase of fixing time. In addition, the mounting plate
requires to be highly sealed because a fuel leaking problem is likely to happen.
On the other hand, another fuel supply device for an internal combustion engine
is disclosed in Patent Application Publication No. 2003-74436. A fuel pump
mounting structure described in Patent Application Publication No. 2003-74436
has an opening formed at a top surface of a fuel tank. A suction side located at a
distal end of the fuel pump has a filter.
However, the fuel pump mounting structure disclosed in Patent Application
Publication No. 2002-74436 has a construction to support the fuel pump that
projects long downward from the lid, which is a mounting plate placed on an
upper section of the fuel tank for the fuel pump, to suck the fuel in from a
bottom of the fuel tank. Such a structure, in which the fuel pump is large spaced
apart downward (i.e., in a vertical direction relative to a mounting surface) from
the mounting plate of the fuel pump, makes a large moment against the
mounting plate, if the mounting plate is disposed at a side surface of the tank to
vertically extend. This structure can cause problems regarding the strength and
seal functions of the mounting plate, similarly to the structure disclosed in Patent
Application Publication No. 2002-106440. Also, the structure that the fuel pump
is large spaced apart in the vertical direction is not suitable for a bottom surface
of the fuel tank.


OBJECT OF THE INVENTION
The present invention is made in consideration of the above-mentioned
conventional art. The object of the present invention is to provide a fuel pump
mounting structure for a vehicle engine, which is arranged to have a mounting
plate for a fuel pump disposed at a side surface or a bottom surface of a fuel
tank to decrease a moment against the mounting plate, to surely support the
fuel pump under a stable condition without requiring a large and firm
construction, and to improve a seal function. The present invention also provides
a vehicle installing the fuel pump mounting structure.
SUMMARY OF THE INVENTION
In order to accomplish the objects, the present invention provides a mounting
structure for a fuel pump of a vehicle engine in which an opening is formed in a
side surface or a bottom surface of a fuel tank, a fuel pump assembly comprising
a cylindrical pump body and a filter coupled with a suction side of the pump body
is accommodated in an inner space of the fuel tank relative to the opening, a
flange section of a housing that encloses the cylindrical pump body abuts on a
surrounding area of the opening outside of the fuel pump, a mounting plate is
covered from the outside of the flange section, and the fuel pump assembly is
fixed to the opening through the mounting plate and the flange section, the
mounting structure for a fuel pump of a vehicle engine characterized in that an
axis of the cylindrical pump body extends generally parallel to a mounting
surface of the mounting plate, and the cylindrical pump body and the filter are
arranged to be overlapped with each other.


According to the present invention, because the axial direction of the cylindrical
pump body extends parallel to the mounting plate of the fuel pump, the fuel
pump does not leave from the mounting plate in a vertical direction. Thus, the
moment against the mounting plate can be inhibited from increasing. Also,
because the fuel pump is disposed such that the filter coupled with a distal end
side of the fuel pump overlaps with the fuel pump, the moment against the
mounting plate can be further reduced in comparison with a structure in which
the filter elongates from the distal end of the fuel pump simply outward along
the axial direction. Thereby, the fuel pump can be surely supported under a
stable condition within the fuel tank using the simple and compact mounting
plate, and possibility of leaking can be reduced.
Also, in one arrangement of the present invention, the fuel tank is a saddle type
fuel tank that straddles a body frame, and the opening is formed in a side wall
surface or a bottom surface located inside of the saddle type fuel tank.
According to this arrangement, in a saddle type fuel tank that can be used
particularly for a motorcycle and has a configuration for straddling a body main
frame, by positioning a mounting plate in a side wall surface or a bottom surface
of either one of inside portions of a right and left side fuel reservoir section that
interpose the main frame therebetween, the mounting plate and conduits,
including a conduit toward the fuel pump, can be compactly placed without
having the tank's external expanded out.
Also, in another arrangement of the present invention, a fuel passage includes
the filter, the cylindrical pump body, and a member through which fuel flows
from the filter to the cylindrical pump body, and the fuel passage is folded back.


According to this arrangement, by making the configuration of the fuel passage
that includes the filter, the conduit disposed on the suction side of the cylindrical
pump body, and the cylindrical pump body be a folding back configuration, the
filter and the cylindrical pump body overlap with each other in a view of radial
direction outward from the cylindrical pump body. Thus, the moment added to
the mounting plate by the pump fixed to the mounting plate in a cantilevered
state, i.e., the pump having an end that is affixed to the mounting plate and the
other end that is not affixed to anything so as to be a free end, can be reduced.
Thereby, the fuel pump can be surely supported under a stable condition, and a
high seal function can be obtained.
Also, in a further arrangement of the present invention, the opening is formed in
the side wall surface located inside of the saddle type fuel tank, and the filter is
disposed below the cylindrical pump body.
According to this arrangement, by placing the mounting plate in the side wall
surface located inside of the saddle type fuel tank, affixing the fuel pump to the
side wall surface inside, and disposing the fuel pump below the fuel pump, the
high seal function can be obtained and the fuel in the bottom of the tank can be
efficiently sucked up, with a compact construction and without making the
moment against the mounting plate being large.
Also, in a further arrangement of the present invention, the opening has an
elliptic shape, and a longitudinal axis of the opening extends generally
horizontally ( both horizontally and substantially horizontally extending states are
included)) and generally parallel (both parallel and substantially parallel
extending states are included) to the axis of the cylindrical pump body.


According to this arrangement, by putting the fuel pump assembly into the inner
space of the tank through the opening that has the elliptical shape extending
generally horizontally, and attaching the fuel pump to extend generally
horizontally, a fuel tank that is compact in a vertical direction, i.e., a fuel tank
which size is small in the vertical direction, can be obtained.
Also, in a further arrangement of the present invention, the cylindrical pump
body and the filter are spaced apart from each other in a direction normal to the
axis of the cylindrical body.
According to this arrangement, relative to the direction of the longitudinal axis of
the pump, the pump and the filter disposed at its end are connected with each
other so as to overlapped with one another, and relative to the direction normal
to the axis of the pump, the pump and the filter are spaced apart from each
other. Thus, when the fuel pump assembly is installed in the inner space of the
tank through the opening, first of all, the filter can be inserted into the space,
and then the cylindrical pump body can be inserted while its physical or angular
positions are changed in sequence. Thereby, the fuel pump assembly with
increased volume can be installed in the space of the tank.
Also, in a further arrangement of the present invention, a mounting structure for
a fuel pump of a vehicle engine is provided with a fuel pump assembly
accommodated in an inner space of a fuel tank and mounted onto the fuel tank
by a mounting plate, and characterized in that the fuel pump assembly includes
a cylindrical pump body and a filter attached to the cylindrical pump body, the
cylindrical pump body is disposed such that an axis of the cylindrical pump body
extends along a mounting surface of the fuel tank to which the mounting plate is


affixed, and the filter is disposed such that at least a portion of the filter is
located out of the cylindrical pump body in a radial direction of the pump body.
According to this arrangement, because the axial direction of the cylindrical
pump body extends along the mounting plate of the fuel pump, the cylindrical
pump body does not leave from the mounting plate in a vertical direction. Thus,
the moment against the mounting plate can be prevented from increasing.
Further, the filter placed at its end of the fuel pump is disposed such that at least
a portion of the filter is located out of the cylindrical pump body in a radial
direction of the pump body. The arrangement can further reduce the moment
against the mounting plate in comparison with an arrangement in which the filter
is not placed in any position spaced in the radial direction of the pump body and
the filter elongates from the distal end of the fuel pump along the axial direction.
Thereby, the fuel pump can be surely supported under a stable condition within
a fuel tank using the simple and compact mounting plate, and possibility of
leaking can be reduced.
Also, in a further arrangement of the present invention, an opening is formed in
a side surface or a bottom surface of a fuel tank, the mounting structure for a
fuel pump further comprises a housing attached to the opening, the housing
encloses the cylindrical pump body inside thereof, and has a flange section
abutting on a surrounding area of the opening outside, and the mounting plate
extends over the flange section to fix the flange portion to the fuel pump body.


According to this arrangement, because the housing encloses the cylindrical
pump body inside thereof, and its flange section abuts on the surrounding area
of the opening, the cylindrical pump and the housing are firmly fixed to the fuel
tank. Thus, the position of the cylindrical pump body does not change relative to
the fuel tank even due to travel motion of the vehicle or to vibration. A fuel
pump mounting structure that is superior in durability is realized, accordingly.
Also, in a further arrangement of the present invention, the fuel pump mounting
structure includes a fuel pipe having an end with which the cylindrical pump
body is coupled, a trunk portion of the fuel pipe bending toward the filter, and
another end with which the filter is coupled, and a fuel flow direction in the
cylindrical pump body and a fuel flow direction in the filter are reversed with
each other.
According to this arrangement, the fuel pipe that connects the cylindrical pump
body and the filter with each other is bent, and the filter is disposed such that
the respective flow directions in the filter and the cylindrical pump body are
reversed with each other. Thus, the filter is positioned in the proximity of the
mounting plate of the cylindrical pump body. The moment against the mounting
plate by the cylindrical pump body and the filter is reduced.
Also, a vehicle configured in accordance with the present invention has the fuel
pump mounting structure described above. According to the present invention, a
vehicle that has the compact fuel tank can be realized. Particularly, a vehicle
such as a small size motorcycle can have a fuel tank that is suitable for a size
thereof.

invention.

Figure 4 is a detailed view illustrating a mounting portion of a fuel pump
assembly of Figure 1.
DETAIL DESCRIPTION OF THE INVENTION
Figure 1 is a vertical cross-sectional elevation view of an embodiment of the
present invention. In the illustrated embodiment, a fuel pump structure is shown
as being accommodated within a saddle type fuel tank that straddles a body
frame of a motorcycle. The saddle type fuel tank 1 has a configuration to
straddle a main frame 2 extending fore to aft along a vehicle body (not shown).
The main frame 2 is affixed to a head pipe through which a steering shaft
coupled with a handle bar that is not shown extends. The main frame 2 is a
pipe-shaped frame and is disposed to extend to a location below a seat. The
main frame 2 supports an engine (not shown) via an engine bracket 3.
The fuel tank 1 has right and left fuel reservoir sections la, lb on the sides of
the main frame 2. The fuel tank 1 also has an opening 5 defined at a side wall 4
located inside of the fuel reservoir section lb on the right hand side of the figure.
An inside space next to the opening 5 accommodates a fuel pump assembly 6.
The fuel pump assembly 6 is constituted with a cylindrical pump body 7 and a
filter 9 coupled through a fuel pipe 8 which is connected to a suction side


located at a distal end of the fuel pump body 7. A housing 11 is unitarily formed
with the pump body 7. An end portion of the housing 11 has a flange cover 10
that closes the opening 5. A flange section 10a, which is a peripheral portion of
the flange cover 10, abuts on a surrounding area of the opening 5 outside of the
fuel tank. A ring-shaped mounting plate 12 covers the flange section 10a outside
of the fuel tank. The mounting plate 12 fixes the flange cover 10 to a portion of
the side wall 4 surrounding the opening 5 by bolts 13 and cap nuts 15 with a
seal member 14 interposed.
Figures 2 and 3 are side and bottom plan views illustrating the fuel tank of
Figure 1, respectively. The mounting plate 12 covers the flange section 10a that
is the peripheral portion of the flange cover 10 of the fuel pump assembly 6. Six
of bolts 13 (FIG. 2) fix the flange section 10a to the surrounding area of the
opening 5 of the fuel tank 1. The opening 5 has an elliptical shape. A
longitudinal axis of the opening 5 extends generally horizontally. The direction of
the axis coincides with an axial direction (longitudinal direction) of the pump
body 7. The fuel pipe 8 is connected to a front end of the pump body 7 that is
the suction side thereof through a joint 16. The fuel pipe 8 bends downward in
its trunk portion 8a. The filter 9 is coupled with a bottom end of the fuel pipe 8
to extend toward the pump body 7. The filter 9 is positioned below the pump
body 7. Because the fuel pipe 8 extending from the front end of the pump body
7 along the axial direction of the pump body (i.e., forwardly) bends downward, a
fuel passage of the suction side, which is constituted with the fuel pipe 8 and the
filter 9, has a folding back configuration. Also, the pump body 7 and the filter 9
are vertically spaced apart from each other to be overlapped with one another in
the top or bottom plan view. The fuel suctioned from the filter 9 flows toward a
portion where the fuel pipe 8 is coupled with the filter 9 and further flows
through the fuel pipe 8. Afterwards, the fuel turns 90 degrees in the trunk


portion 8a of the fuel pipe 8 and flows into the pump body 7. Thus, a fuel flow
direction Fl in the filter 9 and a fuel flow direction F2 in the pump body 7 are
reversed from each other. Because of the arrangement, the center of gravity of
the filter 9 approaches the center of gravity of the pump body 7. The external
force pressing the mounting plate 12 thus can be reduced by the moment of the
fuel pump assembly 6 that is mounted onto the mounting plate 12 in a
cantilevered state. In other words, the external force can be reduced by the fuel
pump assembly 6 in which the pump body 7 is fixed to the mounting plate 12
while the side of the filter 9 is free.
Each right or left bottom end of the fuel tank 1 has a hole 17 through which a
grommet for mounting a body cover (not shown) can extend. Also, a rear end of
the fuel tank 1 has a hole 18 (FIG. 3) through which a grommet for mounting a
body frame (not shown) can extend. Reference numeral 19 denotes a liquid level
detecting device and reference numeral 20 (FIG. 2) denotes a fuel inlet. The fuel
tank 1 has support members 21 with which the fuel tank 1 is mounted onto the
body frame. Each support member 21 is placed at a location in a front area of
the side wall 4 (FIGS. 1 and 3) that extends on the right or left hand inside of
the fuel tank 1. The support members 21 hold a bracket that is affixed to the
main frame 2 (FIG. 1) to sustain the fuel tank 1 on the main frame 2. Reference
numeral 22 denotes a fuel outlet with which a fuel hose (not shown) is coupled.
Reference numeral 23 denotes an electric power source connector.
Figure 4 is a detailed view illustrating a mounting portion of the fuel pump
assembly of FIG. 1. The opening 5 is provided in the side wall 4 of the fuel tank
with the opening 5 folded back into the internal space of the tank. The flange
cover 10 of the fuel pump assembly 6 is affixed to the side wall 4 of the fuel tank
via the seal member 14 to close the opening 5. The ring-shaped mounting plate
12 extends over the peripheral flange section 10a of the flange cover 10 and is

affixed by six bolts 13 (FIG. 2) as described above. The fuel outlet 22 protrudes
beyond the flange cover 10. The fuel hose is coupled through a coupler that is
not shown.
The flange cover 10 further has the power source connector 23 which is
connected to a battery (not shown) mounted on the motorcycle through a
harness coupler 24 and a harness 25. The power source connector 23 is also
connected to a power source terminal 26 that is disposed on an inside surface of
the flange cover 10 to supply electric power to the fuel pump through a cable
that is not shown.
