Abstract: A relief valve comprises a ball body separated from a seat member when a pressure of a working oil from a supply passage exceeds a set pressure, and a ball-body support member biased by a biasing member and supporting the ball body. The ball-body support member comprises a holding recess portion for holding the ball body and a taper portion formed around the holding recess portion and inclined so as to become deeper toward the holding recess portion.

Abstract: A variable displacement vane pump includes: a restrictor configured to impart resistance to flow of working fluid discharged from the pump chambers; a control valve configured to introduce the working fluid which is discharged from the pump chambers to the first fluid pressure chamber as a differential pressure between upstream and downstream of the restrictor is increased, the control valve being configured to discharge the working fluid in the first fluid pressure chamber as the differential pressure between upstream and downstream of the restrictor is reduced; a suction passage configured to guide the working fluid to be sucked into the pump chambers, the suction passage being configured to always communicate with the second fluid pressure chamber; and a guiding passage configured to allow communication between the control valve and the second fluid pressure chamber, the guiding passage being configured to guide the working fluid, which is discharged from the first fluid pressure chamber to the control valve, to the second fluid pressure chamber.
