    摘要： A variable-displacement vane-pump has a rotor which is rotatably supported by a pump housing in coaxial relationship therewith, and a cam ring interposed between the rotor and the pump housing in eccentric relationship with the pump housing. The rotor has radially outwardly slidable vanes on its outer peripheral surface in contact with an inner surface of the cam ring. Two side plates are disposed on both sides of the vanes, thereby defining pump chambers between every adjacent vanes. An arc-shaped intake port and an arc-shaped exhaust port are formed in one of two side plates, and respectively open into the pump chambers along one side face of the cam ring. In the other side face of the cam ring, a groove is formed except for the region corresponding to the exhaust port, and a partially cut off annular friction ring is disposed within the groove while urged by a seal ring into close contact with the other side plate. A pressure compensating recess having a configuration which conforms to that of the exhaust port and communicating with the pump chambers is formed in the other side face of the cam ring except for the region wherein the groove for the friction ring is formed.

    摘要： An automatic transmission including gear trains, which are constructed of at least three planetary gear sets each having three rotating members. A first clutch is arranged closer to an input shaft than the first planetary gear set for connecting any one of the rotating members of the first planetary gear set arranged adjacent to the input shaft. A second clutch is also arranged closer to the input shaft than the first planetary gear set for connecting another of the rotating members of the first planetary gear set and the input shaft. A third clutch is interposed between the first planetary gear set and the second planetary gear set for connecting any one of the rotating members of the second planetary gear set arranged at the opposite side to the input shaft across the first planetary gear set and the any one or the another of the rotating members of either one of the first clutch and the second clutch or the first planetary gear set. A fourth clutch is interposed between the first planetary gear set and the second planetary gear set for connecting the another of the rotating members of the second planetary gear set and the any one or the another of the rotating members of the first clutch, the second clutch or the first planetary gear set.

    摘要： Herein disclosed is a brake system for use with an automatic transmission for braking a rotatable member such as a brake drum, which is accommodated in a casing and connected to the sun gear or the like of a planetary gear mechanism, by bringing a brake band having two ends into contact with the outer circumference with the rotatable member. The brake system comprises: a cylinder tube so held in a predetermined position in the casing as to move forward and backward in the tangential direction of the rotatable member; a piston fitted in the cylinder tube; a piston rod united with the piston and projecting from the cylinder tube such that it is connected to one end of the brake band; an anchor rod so held in a predetermined position in the casing as to move forward and backward in the tangential direction of the rotatable member and conneced to the other end of the brake band; a connecting member for connecting the cylinder tube and the anchor rod so tha they may move together forward and backward; and a valve mechanism disposed in the cylinder tube and adapted to be opened, when the cylinder tube is moved by a force received in a predetermined direction from the brake band through the piston rod to either apply a fluid pressure in a direction to reduce the fastening force by the brake band or release the fluid pressure.
