Abstract:
The present invention provides a swash plate, for a swash plate compressor, which is excellent in a resistance to the occurrence of seizing in a condition where an extreme pressure is generated owing to local contact between the swash plate and a shoe which slides thereon and in a condition where lubricating oil is depleted, capable of preventing cavitation-caused erosion of a resin film when the swash plate is operated at a high surface pressure and a high speed in the presence of the lubricating oil and the swash plate compressor having the swash plate. A swash plate (3) for a swash plate compressor is so constructed that inside a housing (1) where a refrigerant is present, the refrigerant is compressed and expanded by converting a rotational motion of the swash plate (3) mounted perpendicularly and obliquely on a rotational shaft (2) by directly fixing the swash plate (3) to the rotational shaft (2) or indirectly fixing the swash plate (3) to the rotational shaft (2) through a coupling member into a reciprocating motion of a piston (5) through a shoe (4) which slides on the swash plate (3) into a reciprocating motion of a piston (5) through a shoe (4) which slides on the swash plate (3). A resin film containing 25 to 70 parts by weight of fluororesin and 1 to 20 parts by weight of graphite for 100 parts by weight of matrix resin and having a tensile shear adhesive strength not less than 25 MPa is formed on a sliding contact surface of the swash plate (3) on which the shoe (4) slides.
