    • A wet type clutch which has its piston moved by the difference of the pressure in two oil chambers at the two sides of the piston while shutting the communication between the two oil chambers with a friction member adhered to either of the piston or a front cover to be engaged by the piston. An annular groove for communicating with such one of the two oil chambers as will take a lower pressure when the clutch is applied is formed in the surface, to which the friction member is adhered, and/or the adhered surface of the friction member itself, to reduce the pressure acting to return the piston. A seal or high porosity material may also be used to reduce the oil pressure acting on the piston.
    • 一种湿式离合器,其活塞通过活塞两侧的两个油室中的压力差移动,同时用粘附到活塞或前盖上的摩擦构件关闭两个油室之间的连通, 被活塞接合。 用于与两个油室中的这一个连通的环形凹槽在摩擦件附着的表面和/或摩擦件本身的粘附表面上形成在施加离合器时的较低压力, 以减小作用以使活塞返回的压力。 也可以使用密封或高孔隙率材料来降低作用在活塞上的油压。
