<p>PURPOSE:To prevent drag torque surely by installing an accumulator on a clutch circuit to a clutch pressurizing chamber and connecting a drain port of the accumulator to a clutch multiplate lubricating circuit. CONSTITUTION:An accumulator 21 is mounted to an accumulator circuit 20 and a piston is provided with a tapered face 27 which becomes thinner to a pressure storage chamber 26 side, and one end of an escape hole 28 is opened on the tapered face 27 and the other end of the hole 28 is connected to a drain 29. The escape hole 28 can be closed by a movable piston 24. Then, oil is not flowed to a lubricating circuit when clutch pressure is off and generation of drag torque can be prevented.</p> |
