摘要： In a variable displacement vane pump employing a cam ring, a pump rotor, and a plurality of vanes, each slidably fitted into the rotor, a biasing member is provided to force the cam ring in a direction that a geometric center of an inner peripheral surface of the cam ring and a rotation center of the rotor are spaced apart from each other. A force, by which the cam ring can be oscillated against the biasing member in accordance with a buildup of a pressure in a pump discharge portion, acts on the inner peripheral surface of the cam ring.

摘要： An oil pump effects a pumping action to deliver oil from an inlet port to a first outlet port and also to a second outlet port. An oil supply passage is connected to the second outlet port. A regulator valve has a bore, a spool disposed in the bore, a pressure chamber, and a pressure admission port connected to the oil supply passage and communicating with the pressure chamber. A branch passage connected to the oil supply passage opens to the bore. The regulator valve also has relief port connected to the inlet port and opening to the bore, and a transfer port connected to the first outlet port. The spool disposed in the bore is moveable responsive to pressure within the pressure chamber between a first position in which the transfer port is connected to the branch passage and a second position in which the transfer port is connected to the relief port.
