Abstract: A variable capacity compressor has a control element rotatably arranged within a cylinder, which has two pressure-receiving portions slidably received, respectively, in first and second pressure working chambers formed in the cylinder such that the first pressure working chamber is divided into a first lower-pressure chamber and a first higher-pressure chamber, and the second pressure working chamber into a second lower-pressure chamber and a second higher-pressure chamber. The first and second lower-pressure chambers are supplied with low pressure. A first passage extends between one of the first and second higher-pressure chambers and a compression space for supplying the former with discharge pressure from the latter. A second passage communicates between the first and second higher-pressure chambers. A control valve device is operable in response to suction pressure in the compressor for controlling pressure within the first and second higher-pressure chambers.

Abstract: A compact change speed transmission comprising two planetary gear sets which are selectively controlled by clutches and brakes to provide four forward speed ratios and a reverse speed ratio. There are a forward clutch, a forward one-way clutch, and a low one-way clutch which, when the forward clutch is engaged, provide a path of transmission of reaction to a stationary part thereby establishing a path of transmission of torque through at least a part of two planetary gear sets to establish a predetermined one forward speed ratio. A low and reverse brake and an overrun clutch are provided. When both of them are engaged, they hinder the action of the low one-way clutch and that of the forward one-way clutch thereby providing engine braking during running with the predetermined one forward speed ratio. For compact arrangement, the overrun clutch is disposed within a clutch drum of the forward clutch with its actuating piston slidably received by an actuating piston of the forward clutch.

Abstract: Input and output members (19), (28) and a clutch disc (32) are coaxially rotatable relative to each other, the clutch disc (32) being frictionally engageable with the input member (19). A coil-would spring (33) is wound around the input member (19) and connected at its ends to the clutch disc (32) and output member (28). An electromagnetic coil (26) may be energized to attract the clutch disc (32) into frictional engagement with the input member (19), causing the coil-wound spring (33) to tightly wind around the input member (19) and drivably connect the input member (19) to the output member (28). A spring (41) quickly and smoothly disengages the clutch disc (32) from the input member (19) when the coil (26) is de-energized. A plurality of pins (36) extending through the clutch disc (32) ensure parallel movement of the clutch disc (32) toward and away from the input member (19).
