Abstract

PURPOSE: To prevent oil from being sealed and locked in the pump chamber and adjust the amount of discharge smoothly, by providing an oil hole which links the pump chamber in the distributor to the inlet and the outlet alternately.
CONSTITUTION: Pump chamber 30 is provided with plunger 38, which makes reciprocating motion in coordination with the rotation of distributor 29 so that it is moved backward when oil hole 31 is linked to inlet 25 and it is moved forward when oil hole 31 is linked to outlet 26. It is designed so that the amount of discharge can be varied by adjusting the reciprocating motion strokes of plunger 38 and that oil hole 31 is linked to at least either inlet 25 or outlet 26 at all times. By this, oil is prevented from being sealed and locked inside pump chamber 30, and it is possible to adjust and operate plunger 38 smoothly. As a result, the amount of discharge can be adjusted smoothly and exactly.
