  • Publication number: 20030136256
    Abstract: A variable capacity swash plate compressor includes a thrust flange 40 fixed to a shaft 5 and rotating in unison with the shaft 5, a swash plate 10 connected to the thrust flange 40 via a linkage 42 and rotating in unison with the thrust flange 40 according to rotation thereof, a hinge ball 9 slidably mounted on the shaft 5, for limiting an angle of the swash plate 10 with respect to the shaft 5, and a piston 7 connected to the swash plate 10 via shoes 11 relatively rotating on sliding surfaces 10a, 10b of the swash plate 10, and performing linear reciprocating motion within a cylinder bore 6 according to rotation of the swash plate 10, wherein the angle of inclination of the swash plate 10 changes according to a change in pressure in a crankcase 8 within which the swash plate 10 is received, to thereby change a length of stroke of the piston 7.
