ABSTRACT:
A swash plate compressor is provided. The swash plate has sliding surfaces on opposite sides thereof. Pairs of shoes, each of which has a substantially semispherical shape, slide on the sliding surfaces of the swash plate. Each piston is connected to the swash plate via a corresponding pair of the shoes. Guide grooves are each axially formed in an inner peripheral wall of the housing along a path of the linear reciprocating motion of the corresponding piston. Each piston has a body having a first concave portion for supporting a corresponding pair of the shoes, a swash plate-side end having a second concave portion for supporting another of the corresponding pair of the shoes, and a bridge integrally connecting the body and the swash plate-side end such that these portions are axially opposed to each other with space therebetween. The bridge extends radially outward with respect to an outer peripheral surface of the body, and is slidably fitted in a corresponding guide groove.
