ABSTRACT:
A hydraulic control device includes an oil pan; an oil pump; a strainer; a pressure regulating valve; an oil cooler; 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.
