Abstract (en)
This vibrating pump, for a liquid, comprises an electromagnet (5) attracting a movable magnetic core (7) upon which there also acts a return spring (9) and which is connected to a diaphragm (10) or to a movable piston in a pumping chamber (2) positioned between a liquid inlet (3) and outlet (4). Power is supplied to the core (6) of the electromagnet periodically, to obtain alternating intake and exhaust phases. The outlet (4) is connected to a hydraulic accumulator (16) having an elastic action which, when the pump is in the intake phase, restores to the user circuit (18) a quantity of liquid admitted into this accumulator (16) when the pump is in the exhaust phase. The total output of the pump is thus improved. <IMAGE>
