Patent ID: 7992385

Claim:
A hydraulic control device comprising: an oil pan; an oil pump; a strainer that is provided between the oil pan and an intake port of the oil pump; a pressure regulating valve that adjusts a hydraulic pressure of hydraulic oil supplied from the oil pump to a predetermined pressure; an oil cooler that is supplied with the hydraulic oil whose pressure has been adjusted by the pressure regulating valve and that cools the hydraulic oil; a cooler bypass valve with an input port that is connected with a cooler supply oil passage through which the hydraulic oil to be supplied to the oil cooler flows, wherein the input port is communicatively connected with an output port when the hydraulic pressure of the hydraulic oil within the cooler supply oil passage is equal to or greater than a predetermined valve opening pressure; and a cooler bypass oil passage that connects the output port of the cooler bypass valve with an intake oil passage between the strainer and the intake port of the oil pump.
