POWER TRANSMITTING DEVICE

摘要

A drain port (72e) is formed in a C1 relay valve (70) and connects to an input port (72c) (an oil path (55) for the discharge port of an electromagnetic pump (60)) when an input port (72b)(an oil path (53) for the output port of a linear solenoid valve (SLC1)) and an output port (72d)(an oil path (56) for a clutch (C1)) are connected and at the same time the connection between the input port (72c) and the output port (72d) is disconnected. A check valve (82) is attached to the drain port (72e) through a drain oil path (59). As a result of the configuration, even if the leakage of high-pressure oil occurs on the input port (72c) side, the oil can be drained through the drain port (72e), the drain oil path (59), and the check valve (82).
