のバルブユニツト。 In a vehicle power transmission device comprising a lockup clutch, a separate clutch, and a torque converter for transmitting the driving force of the engine to the transmission, a sequence valve is installed in the hydraulic system from the oil pump to the torque converter, A hydraulic circuit provided with a directional control valve on the upstream side of the sequence valve is branched and connected to the actuator of the separate clutch, and a hydraulic circuit provided with a directional control valve and a reducing valve is locked up on the upstream side of the sequence valve. A valve unit for a power transmission system for a vehicle, characterized in that the valve unit branches into an actuator of a clutch, connects a back pressure side drain circuit of each actuator to a return circuit of a torque converter, and provides a sequence valve downstream of the junction.
