Abstract

PURPOSE: To permit convenient capacity adjustment with a simple construction by coupling an intake valve operating rod, which on-off operates an intake valve, to a cam and permitting free adjustment of the phase angle between a flange and the cam.
CONSTITUTION: A cam 34 is a circular cam having a stepped portion 34a, which is so designed as to urge and forcibly displace an end 30a of a valve operating rod 30 and thus open an intake valve 22. The cam 34 is coupled through a transmission mechanism to a rotary drive shaft for causing reciprocation of a plunger 14 such that the cam 34 completes one rotation with one reciprocation of the plunger 14. The pump discharge can be adjusted by 0W100% while maintaining linear relation through continuous variation of the phase deflection angle of the cam 34 with respect to the discharge stroke of the plunger 14.
