'LIQUID LEVEL CONTROL DEVICE'

Abstract A liquid control device for automatic regulation of liquid level in reservoirs of the like. The device comprises a housing, means to monitor the liquid level in reservoir comprising a central axial bar adapted to rotate in a horizontal plane and having first and second ends, the3 first end being rotatably held to the housing, central axial central axial bar having a wedge in between first and second ends, a float fixed to one end of a float arm, the other end of the float arm fixedly connected to second end of central axial bar such thar the float arm causes axial rotation of the central axial with variation of liquid level during operation, a pendulum having first and second ends, first end having a weight and second end connected to wedge of central axial bar wherein the wedge is adapted to allow the pendulum free rotational movement of substantially 90 degree, a contact bar having first and second ends and pivoted to the housing , two support means on either side of the contact bar such that the first and second ends of the contact bar can alternatively rest on two support menas defining two extreme positions of the contat bar, namely "on" and "off" positions, wherein the weight of the pendulum rests on first and second ends of the contact bar depending on the position of the float, wherein the contact bar is adapted to remain in contact with the supports even after the weight leaves contact with the contact bar, and wherein the device is adapted to switch a pump on when the contact bar is in its "on" position.
