PVQ series variable displacement piston pump
(1) The total stroke L of the plunger reciprocating motion is unchanged and is determined by the lift of the cam.
(2) The amount of oil supplied to the plunger per cycle depends on the oil supply stroke, and the oil supply stroke is variable without being controlled by the camshaft.
(3) The start time of oil supply does not change with the change of oil supply stroke.
(4) Turning the plunger can change the final moment of oil supply, thereby changing the amount of oil supplied.
