Abstract (en)
[origin: EP0930434A2] It is sought to accurately control the discharge rate of a pump according to the frequency of a current pulse output applied to an electromagnetic coil. The pump comprises an electromagnetic solenoid 13, a plunger 18 driven thereby, a check valve 2 disposed downstream the plunger 18 and driven by the electromagnetic solenoid 13, and an suction valve 17 provided in the plunger 18 and a discharge valve 8 provided in an inner yoke 6, the check valve 2 being opened when a current pulse output for energizing the electromagnetic solenoid 13 is turned on, thus causing a discharge stroke of the plunger 18. <IMAGE>
