COMPRESSOR WITH IMPROVED SLIDING EFFICIENCY AND HIGH RELIABILITY

摘要

PURPOSE: A compressor is provided to prevent an anti-rotation unit of a piston and an outer peripheral surface of a swash plate from rattling and sticking by the wear of one of the anti-rotation unit and the outer peripheral surface by sliding properly a counter part with a sliding film. CONSTITUTION: Surfaces(8c,8d) of a swash plate(8) and flat surfaces(9c,9d) of shoes(9a,9b) of a compressor slide relatively to each other. A sliding film(C) is formed on the surfaces of the swash plate. The sliding film is made of polyamide imide resin containing at least a solid lubricant. The polyamide imide resin has the glass transition temperature over 270 deg.C and the tensile strength over 200Mpa in a normal temperature and contains imido groups more than amido groups. If the swash plate has an aluminum metal base(81), the sliding film is formed on the base about an intermediate layer(M) made of Alumilite.
