For FCT/EP2003/014388 D fSERTION PART FOR INSERTING INTO A GAS OR LIQUID LINE The invention relates to an insertion part having a housing, which can be inserted into a gas or iquid line, with an annular lip shaped part being arranged in the interior of the housing, held to the interior of the housing with its annular body, which is provided in an area o1 a feeder channel and has at least one lip, that can be displaced by the fluid, and coope ates with an opposing housing wall. A bac i-flow valve is known fixjm DE 1 154 982, which is provided with a housing that can be: inserted into a gas or liquid line, with a sealing body being movably arranged insidi the housing, which seals the flow opening of a feeder channel in the closed posit on. The sealing body of the known back-flow valve is embodied as an essentially hose shaped lip shaped part, extending in the annular direction, which is held inside the hous ng and contacts with its cylindrical housing part, surrounded by the sealing body, the Ip end region in a sealing manner in the area of the flow opening of the feeder chainel. The sanitary insertion part known from DE 1 154 982 is embodied as a back-flow valve, witl I its sealing body being adjusted either to an open or a closed position. The insertion par known from 1 154 982 however is not embodied as a flow regulator, which can adj ist the volume of the flow passing through the water line per time unit depending on a ma (imum value independent from the pressure. Fr >m GB-PS 875 034 another mere back-flow valve is known, which encompasses in its he jsing a cylindrical interior housing space. In this interior housing space a piston-like vg ive unit is guided in a shiftable maimer, which can be displaced xmder the pressure of thi water flowing from the inlet to the opposite face of the interior housing space provided. This piston-like valve unit is provided with a lip shaped piece, which seals in 1 Amended Sheet its resting position the flow openings which penetrate the valve unit and which can be moved into an opai position by water flowing in the flow direction. When an amount of water flows opposite the flow direction, the lip end region of the lip shaped piece is pressed against the wall edge region encompassing the flow openings and effectively couj iteracts the back-flow of the water. Here, too, the insertion part known firom GB-PS 875 034 is neither intended nor suitable as a flow regulator. Fron DE 1 182 487 a back-flow valve is known intended for high operational pressure, in ^vhich the annular channel between the valve housing and a centered insertion body, inserted therein in a streamline shape, is sealed by a sheath-shaped valve piece made froftt an elastic material. While the sealing piece is motioned by the water flowing in the usiial flow direction, an amount of water reversing opposite the usual flow direction pre sses the sealing piece increasingly against the streamlined insertion body so that the an lular channel remains sealed. Cc mparable back-flow valves have also been known from FR 2 426 199, US-PS 2 621 88 ), DE 109 871, FR 1 389 947, DE 938 888. DE 946 760, DE 1 500 206 as well as from D]'. 37 06 737. A; already mentioned, none of these known back-flow valves are capable of adjusting the vclume to a maximum value that can flow through the water line per time unit independent from the pressure. F ow regulators have already been designed, which are provided with a tapering or cone- shaped housing core on the inside of their housing. The housing core is encompassed by aj annular throttle body or control body made from an elastic material, which limits the ci introl gap between itself and the housing core depending on the pressure. When producing the previously known flow regulators, the necessary throttle bodies and control bodies are subject to the elastic characteristics of the rubber material, which can lead to different control features of one insertion part to another. Furthermore, the known insertion parts are usually embodied in multiple parts and are thus expensive in their production. 1 herefore, the object is to provide a multi-use insertion part, which is characterized in a simple production and preferably also in a consistent and secuie function. 1 tie solution according to the invention comprises an insertion part of the type mentioned a I the outset in particular in that the insertion part is embodied as a flow regulator, with it i lip shaped part having at least one throttle body or one control body and being provided with a control lip, its free lip end that extends in a direction of the adjacent housing wall, which control lip limits the control gap and changes depending on pressure, between itself and the adjacent housing wall. The insertion part according to the invention is embodied as a flow regulator. The insertion part, which can be inserted into a gas line or a liquid line as a flow regulator, is p; ovided with a lip shaped part, which is held inside the housing. This lip shaped part hiis at least one control lip, embodied as a throttle body or a control body and aligned w th its free lip end extending in the direction of the adjacent housing wall. This control li] pi 3vided between the control lip and the adjacent housing wall is modified depending on th es jentially in two parts, is also provided with a control lip and due to the fact that the reaction behavior of this control body is less dependent on the elastic features of the m iterial composition used but rather from the shape and the dimensions of the control lil, the insertion part according to the invention is characterized in a constant control function. Hire, a particularly beneficial further development of the invention provides that the insertion part is simultaneously embodied as a back-flow preventer and that the annular lip shaped part of the insertion part has at least one sealing lip, which is provided as a sei ling body, movably arranged inside the housing, and sealing in the closed position the i ow opening of the feeder channel, with the sealing lip in the closed position contacting tiie opposing housing surface in a sealing fashion. 1 he insertion part, simultaneously embodied as a back-flow preventer, is provided with ail annular lip shaped part which is held with its annular body inside the housing. This lip Si taped part has at least one sealing lip that can be displaced by the fluid, and can be nioved by a back-flow of tiie fluid in a direction of an opposite housing surface such that tlie sealing lip in its closed position contacts with its lip end region a housing surface in a sealing manner. When the housing is embodied in one part, the insertion part according tc the invention can be embodied essentially in two parts, namely the housing and the lip sliaped part. This small number of parts is beneficial for the high functional security of the insertion part according to the invention. HiTe, a preferred embodiment of the invention includes for the inside of the housing to be provided with a housing core, which limits a flow opening between itself and the interior ci: cumference of the housing, and the lip shaped part is held with its annular body at the in erior circimiference of the housing and contacts the housing core with its free lip end re;t^on of its sealing lip in a sealing manner in the closed position. It s particularly advantageous for the lip shaped part to be held with its annular body at th« interior circumference of the housing, in order to align the free lip end of the control lip in a direction toward the adjacent housing wall of a housing core. A urther development according to the invention, worth protecting in itself, combines the function of a flow regulator and a back-flow preventer in a single insertion part and pre vides for the lip shaped part to have at least one upstream control lip and/or control lip anc at least one downstream sealing lip. In (rder to achieve a sensitive reaction behavior, largely independent from the material of the flow regulator according to the invention, it is beneficial for the control lip to be aligned with its free lip end region extending in the direction opposite to the flow d rection of the fluid and limiting an annular space open in the upstream direction between itself and the interior circumference of the housing. In this blind-hole shaped, U!)str6am opening annular space, the inflowing fluid impinges Ihe control lip such that the lif) is pressed towards the housing core depending on pressure and thus changes the cuntrol gap limiting and leveling the amount flowing. Ii ordo' to allow the targeted amount of fluid to flow unhindered through the insertion piiit during low as well as high pressures, it is beneficial for the housing wall adjacent to the free lip end of the control lip to be provided with a control profiling, with the control pi ofiling preferably being formed by grooves or moldings aligned in the direction of the fluw. These moldings may also be provided at the housing core in the area of the control li), for example. Due to the fact that the control lip is not pressed in a direction of the adjacent housing wall until a defined pressure value has been reached, the control lip reacts with a distinctly noticeable peak at this pressure value, which can be utilized as a coatrol impulse for subsequent devices downstream. [antinue: pages 5 and on of the original description] [TiUs corresponds to page 4, line 11 of the Translated Application} Here, a sensitive reaction of the insertion part serving at leai;t as a flow regulator is promoted if the molding, preferably evenly distributed over the circumference of the wall of the adjacent housing wall, is arc-shaped or similarly rounded. Ln contrast thereto, the sealing lip of the insertion part serving at least as a back-flow orevcnter can be aligned in the radial direction and, m the closed position, cooperate with m annular flange at the housing core. However, an embodiment is preferred, in which he sealing lip is arranged with its free lip end region extending in the direction of the low. In the event of an undesired back-flow, such a sealing lip, aligned in the flow I irection, can also contact a cylindrical or cone-shaped and/or tapered housing core m a ; eahng manner. 1 crc, it is advantageous for the housing wall adjacent to the free lip end to have a wall s ;chon free from grooves or moldings in the area impinged by the sealing lip. V liiie the housing is preferably made from a suitable dimcnsionally stable metal or, in p; rticular, plastic material, if necessary, one preferred embodiment of the invention pi jvides for the lip shaped pjirt to be made from an elastic rubber or plastic material. A) hough the reaction pressure and the reaction behavior of the confrol and/or sealing lips cai be solely influenced and determined by the shore-hardness of the rubber-elasflc matirrial, for example, an embodiment is preferred, though, in which the reaction pressure and the reaction behavior of ttie control lip and/or the sealing lip is predetermined by the length, the thickness, or a similar design and dimension of the lip(s) and/or by the material characteristics of the lip shaped part. For I xample, the lip shaped part can be inserted and held in a groove, which is provided at th embk>diment is preferred, in which the hoiising of the insertion part is provided in at least two Darts, and the annular lip shaped part is held with its annular body between two adjai ent housing parts. Here it can be beneficial for the annular body of the lip shaped part to be embodied as a hoxissng part seal for the adjacent housing parts. In order to be able to perhaps optimize the functions of the insertion part according to the invei tion with regard to control flow and preventing back-flow, it can be advantageous for tie control body of the lip shaped part at both sides to comprise at least one control and/ alloc ited flow opening and/or in the area of a control gap. Here a further development according to the invention, for which independent protection is waiTanted, provides that one control lip and one sealing lip are provided at both sides of thi control body of a preferably generally star shaped or x-shaped lip shaped part. The lips a-e located on the opposite sides of the control body and are each allocated to a central gap with a downstream flow opening, Such a star shaped or x-shaped lip shaped part c an for example be glued, welded or mounted in a similar manner to a downstream face (fan annular housing wall, which is arranged approximately in the center inside the housiiig. This component can essentially be made from two components, namely the housing and the lip shaped part connected thereto. In order to provide the lip sh^ed part in the insertion part with a solid and safe fastening, it is idvantageous for the annular body of the lip shaped part to be fastened in a housing chamber between the upstream housing part and the downstream housing part. Here, a preferred embodiment of the invention provides for the housing chamber to be closed exec pt for an annular gap and that the annular gap is penetrated by a connecting part of the lip shaped part, coimecting its annular body with the control and/or sealing lips. The imall production expense for the insertion part according to the invention is reduced ever further if the housing parts adjacent to the lip shaped part can be snapped together. For the same reason it is useful if die housing core, preferably cone-shaped or tapering in the flow direction, is connected to an upstream housing part via an at least radially extending connection bar in one piece. Additional embodiments of the invention are described in the other subclaims. In the folio mng, the invention and its essential features is explained in greater detail using the dra\\ ings. The irawings show: Fig. an insertion part, in a longitudinal cross-section, embodied as a flow regulator, with its control lip cooperating with a cone shaped or tapered central housing core also located inside the housing, Fig.: an insertion part, also shown in a longitudinal cross-section similar to the embodiment of Fig. 1, which is embodied both as a flow regulator as well as a back-flow preventer and with its lip shaped part additionally comprising a downstream sealing lip, Fig.: a flow regulator comparable to the one in Fig. 1 shown during increased pressure conditions in longitudinal cross-sections (cf Figs. 3a, 3c, 3e) and cross-sections (cf Figs. 3b, 3d, 3f), and Fig. 4 various embodiments of the insertion part, adapted to the desired reaction behavior, and the performance diagrams allocated to the illustrated embodiments. In ti: e Figs. 1 and 2 insertion parts 1,100 are shown, which can be used at least as flow regulators in a gas or liquid line. The insertion parts 1,100 are provided with a housing 2, With an aimular lip shaped part 3 being held against an interior housing circumference. As discernible from Figs. 1 and 2, the housing 2 is provided in two parts, an upstream part tnd a downstream part 4, 5. The lip shaped part 3 is fastened with its annular body 6 in a housing chamber 7 between the upstream and the downstream housing parts 4, 5. This housing chamber 7 is formed in a closed fashion except for an annular gap. The annuiar gap is poietrated by a connecting part 8 of the lip shaped part 3, which connects the aimular body 6 with an annular control lip 9. The (ontrol hp 9 is embodied as a throttle body or control body, limiting a control gap between the control lip 9 and a central housing core 10, with the gap changing depending on pr jssure. As si: own in Figs. 1 and 2, the control lip 9 is aligned with its free lip end region in an opposite direction to the flow direction Pfl of the fluid, and delimits a blind hole-type annul insertion part 1,100, the control Up 9 is pressed, depending on pressure, in the direction of the housing core 10 such that the confrol gap narrows. By this pressure-dependent movement of the control lip 9 and the narrowing of the control gap resulting therefrom, the an ount of fluid flowing per time unit remains generally constant even in strong pressi re variations, with the flow amount remaining within a predetermined tolerance range. A piUticular advantage of the flow regulator 1,100 shown here is that its reaction behdvior is less dependent on the material characteristios of the rubber-elastic throttle body or control body 9 but rather on its design and dimensions. As {hown in Figs, 3a, and 3b, the control lip 9 hardly changes under light pressure. In Fig;{. 3 c and 3d it is discernible that the control lip 9 quickly reacts to slightly rising water pressure and is pressed in the direction towards the housing core 10. This pressure- dej)endant motion of the control lip 9 is discernible as a distinct peak in the curve progression in Figs. 4b, 4d, and 4f. This peak, which is more or less discernible dq)ending on the design of the control lip 9, can be used as a controlling impulse, in orcier to start a flow heater, for example. In tngs. 3e and 3f it is discernible that the control lip 9 is also pressed into the moldings 13 in the housing core during increasing water pressure, with a maximum flow amount pei time unit not being exceeded. Tb s control lip 9 of the insertion part 1 shown in Fig. 4a is predetermined for a low pressure range between 0.2 and 3.0 bar and amounts of liquids between 1 to 8 1/min. For thi 3 purpose, the free lip end region is designed thin and arranged in proximity to the he jsing core 10 even in the resting position. TliC control lip 9 of the insertion part 1 shown in Figs. 4c and 4d is designed for high pri«sure values from 1 to 10 bar and for flow amounts of 1 to 2 l/min. For this purpose, thu free lip end region is designed relatively thick and positioned farther apart from the he using core. Therefore, a higher pressure is required for pressing this control lip 9 into th; moldings 13 ofthe housing core 10. In Fig. 4e an insertion part 1 is shown, which has a very thin and comparatively long cc ntrol Up 9, reaching with its free lip end region to the proximity ofthe housing core 10. T! le insertion part 1 according to Fig. 4e is designed for fluids with low viscosity and/or fluids with little density, such as for example air or other gases, and for low pressure and hign flow amounts per time unit of approximately 801/min. This insertion part can also be used for such ^plications, in which conventional flow regulators with an O-ring shaped throttle body or control body cannot be used. Here, in contrast to conventional flow regulators, the reaction pressure and the reaction behavior can be varied in both areas by an appropriate selection of geometry and material of the lip shaped part 3 and its control lip 9. The reaction pressure of such insotion parts can be designed such, using appropriate geometrical designs by its control lip 9, that the reaction pressure is as low as 0.'. bar, for example.
