Abstract: A swash-plate type compressor comprises a plurality of cylinder chambers parallel to each other, a shaft, a swash plate connected to the shaft for rotation therewith and for wobbling motion due to the rotation, and a plurality of pistons subject to wobbling motion of the swash plate for reciprocation within the respective cylinder chambers. The shaft and the swash plate are connected to each other through a slot formed in one of them and a pin provided on the other, so the swash plate can wobble. A position of a center of rotation of the swash plate is supported by a spool device movable in coaxial relation to the shaft. Displacement of the spool device causes the position of the center of rotation of the swash plate and an inclination thereof to be varied to vary a reciprocative stroke of each piston, thereby controlling discharge capacity of the compressor.

Abstract: A swash plate type compressor has a rotary shaft, an inclined swash plate for rotation with the shaft, and a plurality of pistons connected to the swash plate. Each piston defines at both ends thereof a pair of working chambers. The piston reciprocates while being subjected to a swing motion concomitant with the rotation of the swash plate, to suck a fluid into the working chambers for compression. The swash plate is mounted on the shaft through a support unit which serves to selectively vary the inclination of the swash plate and shift the center of rotation of the swash plate along the shaft. The fluid is introduced from a suction passage through and around the swash plate to suction chambers formed adjacent the working chambers. A bypass passage is formed to directly communicate the suction passage with the suction chamber on one side of the shaft while bypassing the swash plate.
