    • A frictional engagement device for engaging a pair of members relatively rotating around a common axis is improved to obtain a smooth action. A first frictional engaging element is fitted unrotatably and axially movably to one of the relatively rotating member. A second frictional engaging element is unrotatably and axially movably fitted to the other of the relatively rotating member and disposed engageable to the first frictional engaging element. A first cam member which is axially movably fitted to one of the relatively rotating member and disposed apart from the second frictional engaging element has a slanted cam surface. A second cam member which is disposed adjacent to the first cam member on a side of the second frictional engaging element has a slanted cam surface parallelly opposing the cam surface of the first cam member. A piston means which is fitted to the second cam member has a surface engageable with the second frictional engagement element. A spring seat is disposed, not touching the piston means, in a space formed between the piston means and the second cam member. A return spring for biasing the second cam member toward the first cam member is fixed to an unmovable member on one end and fitted the spring seat on the other end. A pushing means selectively pushes the piston means onto the second frictional element through the second cam member to cause a frictional engagement between the piston means and the second frictional element so that the piston member being rotationally dragged with the second cam member and generates a cam force to engage the first frictional engaging element and the second frictional element. A friction decreasing means disposed between the spring seat and the second cam member decreases the friction between the spring seat and the second cam member to prevent the return spring from being rotationally dragged by the second cam member when the second cam member is rotationally dragged.

    • A one-way clutch mechanism suited to shorten its axial dimension and to prevent the production of a shock noise, in which a side clutch member (20 in Fig. 3) is interposed between a stator side member (18) disposed unitarily with a stator and a stationary-shaft side member (22) disposed unitarily with a stationary shaft, and in which the surfaces of the stator side member (18) and the side clutch member (20) confronting each other are respectively formed with oblique planes (18a, 20a), wherein only when the stator has received a turning force of specified direction from a fluid stream, the stator side member (18) and the side clutch member (20) are brought away from each other into the operational connection of the stator side member (18) and the stationary-shaft side member (22) by the cooperation of the oblique planes (18a, 20a).

    • The one-way clutch mechanism of a torque converter which has a short axial dimension, and which neither produces a shock noise (an abnormal sound) nor suffers a power loss in the idle mode thereof. An outer race (30 in Fig. 1) is united with a stator (18), and supports the stator (18) so as to be axially movable and rotatable with respect to a stationary shaft (16). The outer race (30) includes a first side face (32) which is formed with first teeth. An inner race (40) is united with the stationary shaft (16), and includes a second side face (42) opposite to the first side face (32). The second side face (42) is formed with second teeth which can prohibit the rotation of the outer race (30) in one direction, by meshing with the first teeth. The stator (18) and the outer race (30) receive the axial component force of a fluid stream which changes depending upon a speed ratio. Thus, the unitary structure (18, 30) comes near to or away from the inner race (40), thereby to engage or disengage the first teeth and the second teeth.
    • 变矩器的单向离合器机构具有短的轴向尺寸，既不产生冲击噪声（异常声音），也不会在其空转模式下遭受功率损失。 外圈（图1中的30）与定子（18）结合，并支撑定子（18）以便相对于固定轴（16）可轴向移动和旋转。 外座圈（30）包括形成有第一齿的第一侧面（32）。 内圈（40）与固定轴（16）结合，并包括与第一侧面（32）相对的第二侧面（42）。 第二侧面（42）形成有第二齿，该第二齿能够通过与第一齿啮合而阻止外座圈（30）沿一个方向旋转。 定子（18）和外座圈（30）接收根据速比而变化的流体流的轴向分力。 因此，整体结构（18,30）接近或远离内座圈（40），由此接合或脱离第一齿和第二齿。

    • A hydrodynamic clutch which has its piston (16) moved by the difference of the pressure in two oil chambers (18,19) at the two sides of the piston (16) while shutting the communication between the two oil chambers (18,19) with a friction member (17) adhered to either of the piston (16) or a front cover (12) to be engaged by the piston. An annular groove (20) for communicating with such one of the two oil chambers (18,19) as will take a lower pressure when the clutch is applied is formed in the surface, to which the friction member (17) is adhered, and/or the adhered surface of the friction member (17) itself, to reduce the pressure acting to return the piston (16).
    • 一种流体动力离合器，其活塞（16）通过两个油室（18,19）之间的连通关闭而在活塞（16）两侧的两个油室（18,19）中的压力差移动， 其中摩擦构件（17）粘附到活塞（16）或前盖（12）中的任一个上以与活塞接合。 用于与两个油室（18,19）中的一个连通的环形凹槽（20,19）形成在摩擦构件（17）所附着的表面中，当施加离合器时，其将承受较低的压力，并且 /或摩擦构件（17）本身的粘附表面，以减小作用以使活塞（16）返回的压力。
