Abstract
A swash plate-type compressor included a rotatable swash plate and a piston. The piston is connected to the swash plate via at least one shoe and reciprocates in company with each rotation of the swash plate. The swash plate has a layer of a sintered metal impregnated with a resin on at least a swash plate surface sliding against the at least one shoe. A surface of the impregnated layer is ground.
Claims19
A swash plate-type compressor comprising:
- a rotatable swash plate;
- a piston is connected to said swash plate via at least one shoe and reciprocates in company with each rotation of said swash plate;
- and
- wherein said swash plate comprises a layer of a sintered metal impregnated with a resin on at least a swash plate surface sliding against said at least one shoe, and a surface of said layer is ground, wherein said metal comprises a solid lubricant and wherein said solid lubricant is selected from the group consisting of tungsten disulfide, boron nitride, antimony oxide, indium, stannum, argentum, and plumbum.
A swash plate-type compressor comprising:
- a rotatable swash plate;
- a piston is connected to said swash plate via at least one shoe and reciprocates in company with each rotation of said swash plate;
- and
- wherein said swash plate comprises a layer of a sintered metal impregnated with a resin on at least a swash plate surface sliding against said at least one shoe, and a surface of said layer is ground, and wherein said resin is a polyetheretherketone resin.
A swash plate-type compressor comprising:
- a rotatable swash plate;
- a piston is connected to said swash plate via at least one shoe and reciprocates in company with each rotation of said swash plate;
- and
- wherein said swash plate comprises a layer of a sintered metal impregnated with a resin on at least a swash plate surface sliding against said at least one shoe, and a surface of said layer is ground, wherein said resin comprises a solid lubricant and wherein said solid lubricant is selected from the group consisting of tungsten disulfide, boron nitride, antimony oxide, indium, stannum, argentum, and plumbum.
A method for manufacturing a swash plate-type compressor, wherein said compressor comprises a rotatable swash plate and a piston, said piston is connected to said swash plate via at least one shoe and reciprocates in company with each rotation of said swash plate, said method comprising the steps of:
- sintering a metal on said swash plate surface;
- impregnating a resin into a layer of said sintered metal;
- hardening said resin;
- and
- grinding an outer surface of said impregnated layer.
