Abstract:
A hydraulic control device includes: a pressure regulation valve that regulates a hydraulic pressure of oil supplied from an oil pump; a discharge oil passage through which the oil discharged from a fluid coupling flows when a lockup clutch is disengaged; a lubrication oil passage that supplies the oil from the discharge oil passage to a location to be lubricated; a return oil passage that returns the oil drained from the pressure regulation valve to a suction port of the oil pump; a connection oil passage that connects the lubrication oil passage and the return oil passage; and a flow direction regulation valve that is provided in the connection oil passage.
