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. The engaging slot has a section thereof between positions corresponding respectively to a maximum discharge capacity and an intermediate discharge capacity of the compressor, which section is formed into a nonlinear configuration in such a manner that an angle between a normal line of the slot and an axis of the shaft decreases at a position corresponding to a large discharge capacity of the compressor, thereby restraining an increase in inclined moment acting upon the swash plate due to a dead volume occurring in the working chamber on one side of the piston at a large capacity of the compressor.
