Abstract
A swash plate compressor includes a cylinder block having positioned therein a plurality of cylinders and a crank chamber. Each of a plurality of pistons has a head portion and a skirt portion. The head portion of the piston is slidably disposed within one of the cylinders. The skirt portion of the piston slidably abuts on an inside surface of the crank chamber, and by its action the pistons are prevented from nutating axes when the pistons are driven in a reciprocating motion within the cylinders upon rotation of the swash plate. The crank chamber has a truncated cone-shape, the inside diameter of which is reduced between a top dead center and a bottom dead center of the piston. The structure for the swash plate compressor according to this invention reduces vibration and noise caused by the nutation of the pistons.
