Swash plate type compressor with lubricating mechanism of shoe and swash plate.

摘要

A swash plate type refrigerant compressor comprises a compressor housing enclosing therein a crank chamber, a suction chamber and a discharge chamber. A swash plate is tiltably connected to the drive shaft and has two sliding sufaces at axial sides thereof. The swash plate includes a sliding surface which engages a plurality of pairs of shoes. The shoes couple the swash plate to the pistons so that the pistons may be driven in a reciprocating motion within the cylinder bores upon rotation of the swash plate. At least one groove is formed in the sliding contact surfaces between the swash plate and the shoes. The groove captures and retains lubricating oil in the refrigerant in response to the rotation of the swash plate. <IMAGE>
