ABSTRACT:
Disclosed is a sliding shoe for a rotatable swash-plate type refrigerant gas compressor. This shoe is slidably connected between a rotatable swash-plate and a ball rotatably engaged with a piston. One of the major surfaces of the shoe slidably contacts a sliding surface of the swash-plate. A sliding surface of the shoe facing the swash-plate is formed with a flat plane at its center portion and chamfered surface at the remaining portion of the sliding surface. At least the sliding plane of the shoe is coated with a lead alloy. According to the present invention, even if the swash-plate type compressor has no lubrication, abrasion and seizing of the shoe can be reduced to a great extent.
