摘要： A pump is provided, which includes: an internal housing inside which a vane rotor is housed; a pump housing 1 in which the centre of rotation of the vane rotor is immovable and the internal housing is able to move; a first control oil chamber which causes the internal housing to move in a direction of decreasing the discharge volume; and a second control oil chamber which causes the internal housing to move in a direction of increasing the discharge volume; a pressure adjustment valve; a temperature-sensitive valve; and an elastic member which elastically impels the internal housing. A flow passage area of the temperature-sensitive valve changes gradually with change in oil temperature, and the pressure adjustment valve changes a discharge volume in accordance with increase in pressure of the discharge oil.

摘要： [Problem] To provide a relief device for an oil circuit of an engine provided with an oil pressure relief valve and a temperature-sensitive relief valve, with which it is possible for oil to be relieved (expelled) at the intended pressure regardless of the oil temperature, and with which it is possible to simplify the configuration. [Solution] The relief device comprises an oil pump (9), an upstream channel (61) provided from a discharge side of the oil pump (9) to an engine (E), an oil pressure relief valve (A) for relieving oil due to the valve body being moved by oil pressure, and a temperature-sensitive relief valve (B) for relieving oil by sensing the oil temperature and continuously opening and closing. The oil pressure relief valve (A) and the temperature-sensitive relief valve (B) are arranged in parallel in the upstream channel (61).

摘要： An oil pump device includes an oil circulation flow channel; a gear pump section including a drive gear unit and a driven gear unit; a first branching flow channel that branches from the oil circulation flow channel and communicates with the gear pump section; a hydraulic control valve that drives the driven gear unit; a second branching flow channel that branches from the oil circulation flow channel and communicates with a second small-diameter passage section; a solenoid valve that includes a drain discharge port; an orifice that is disposed between the second small-diameter passage section and the solenoid valve; and a spring that elastically urges the driven gear unit. The solenoid valve performs control in such a manner that the second branching flow channel and the second small-diameter passage section are put to a communicating state or a non-communicating state, and that the drain discharge port communicates with the second small-diameter passage section in the non-communicating state.

摘要： A relief device for an oil pump includes a relief valve including a small diameter valve chamber and a large diameter valve chamber and a valve housing that includes a relief discharge section, a temperature sensitive valve, an oil pump, a main channel, a relief channel, and an auxiliary channel. The relief channel causes one side of the small diameter valve chamber and the large diameter valve chamber and the oil pump to always communicate with each other and enables oil to be discharged from the relief discharge section. The auxiliary channel enables the other one side of the small diameter valve chamber and the large diameter valve chamber and the oil pump to communicate with each other. The temperature sensitive valve is included in the auxiliary channel. The temperature sensitive valve controls the auxiliary channel to be in a communication state when oil is at a low temperature and controls the auxiliary channel to be in a non-communication state during high oil temperature.
