Abstract

A swash-plate type compressor comprises a drive shaft, at least one plunger piston, a cylinder block rotatably supporting the drive shaft and defining therein at least one cylinder chamber or bore, the cylinder chamber slidably accommodating the piston to permit an axial reciprocal sliding movement of the piston in the cylinder chamber, a swash plate rotatably mounted on the drive shaft, and a linkage provided between the drive shaft and the swash plate for causing a rotational movement of the swash plate in synchronization with rotation of the drive shaft, while permitting a wobbling movement of the swash plate. The piston includes a bottom section having a recessed portion for receiving a pair of semi-spherical shoes and for slidably holding the swashplate side walls between the shoe pair for the axial reciprocal sliding movement of the piston, and a main skirt section having a through-opening extending in a rotational direction of the swash plate.
