PURPOSE:To enhance the performance and prolong the service life of an electric motor by using oil in an engine transmission system effectively for cooling of the electric motor. CONSTITUTION:In engine run mode, ports (a) and (b) and ports (c) and (d) of a clutch control valve 62 are connected to each other, respectively, to engage an input clutch C1 and feed oil in an oil path B to a torque converter 4. In motor run mode, the ports (a) and (b) and the ports (c) and (d) are shut off each other, respectively, to disengage the input clutch and stop oil feeding to the converter 4. Also ports (k) and (r) of a regulator valve 63 are connected completely to each other to feed all oil from a pump 19 to the oil path B and further feed to a coil cooling oil path D. |
