Abstract:
A variable-capacity swash-plate type compressor, which is constituted so that a crank chamber, inlet chambers, an outlet chamber and cylinder bores connected therewith are demarcated and formed in a housing, so that pistons are accommodated reciprocatably in the respective cylinder bores, respectively, so that a rotor, positioned in said crank chamber, is supported synchronously rotatably onto a driving shaft, supported by the housing, and a swash plate, connected thereto by way of the rotor and a hinge mechanism, is fitted therewith so as to make an inclination angle variable, so that a connecting mechanism, transforming a to-and-fro swinging movement of said swash plate into reciprocating movements of the respective pistons, is interposed between the swash plate and said pistons, and so that the inclination angle of said swash plate is controlled by a pressure in said crank chamber so as to vary an outlet capacity, whereinit is characterized in that an aligning member, which contacts with said swash plate to align said swash plate, is interposed between said driving shaft and said swash plate; an urging means for urging said aligning member onto a side of said swash plate, said urging means is an inclination-angle reducing spring, which urges the swash plate in such a direction that the inclination angle is reduced from the maximum inclination angle to the minimum inclination angle; and said aligning member is disposed between said rotor and said swash plate.
