Abstract
PURPOSE: To enable the eccentrically swivelling motion of an eccentric wheel while firmly press-contacting a peripheral surface of the eccentric wheel to an inner circumferential surface of the pump chamber and improve the efficiency of the pump, by constructing a notched groove on a pump shaft, providing wedge rollers, a bearing and the eccentric wheel and engaging a partition member to the wheel.
CONSTITUTION: A notched groove 12 is constructed on a pump shaft 10, and wedge rollers 16 are put into between a bearing 15 and the notched groove 12. A partition member 27 separates a pump chamber P, formed between the pump casing and an eccentric wheel 14, into a suction chamber Pi and a delivery chamber Pe. A suction port 28 and a delivery port 29 are provided. A cooperating motion of the notched groove 12 and the wedge rollers 16 causes the wedge action to be transmitted to the eccentric wheel 14 permitting said eccentric wheel to eccentrically swivel while firmly press-contacting its peripheral surface to inner circumferential surfaces of the pump chamber. In this way, a rotary pump very efficient with no pulsating motion can be obtained. In addition, an adherent installation of a flexible film to the side of the eccentric wheel can obtain a no-leak pump.
