Abstract

An oil pump (X, XII, XIII) includes a first control valve (4, 204, 304) including a first valve body (42, 242, 342) provided in a first valve housing (41, 241, 341) for reciprocating therein, the first valve body for controlling discharge pressure of working oil discharged from a pump main body (1), a first valve chamber (43, 243, 343) formed in the first valve housing, the first valve chamber being applied with the discharge pressure of the working oil from the pump main body, and a second valve chamber (44, 244, 344) formed in the first valve housing, the second valve chamber being supplied with the working oil, and a second control valve (7, 207, 307) activated on the basis of degree of the temperature of the working oil, the second control valve for controlling oil pressure of the working oil flowed into the second valve chamber.
