CAR AIR-CONDITIONING SYSTEM AND MAXIMUM CAPACITY REGULATING MECHANISM FOR VARIABLE CAPACITY OSCILLATING PLATE TYPE COMPRESSOR

PURPOSE:To reduce the condensing pressure of refrigerant R-22 structurally and obtain a compressor mechanism suitable for the refrigerant R-22 by a method wherein a maximum slant angle regulating means, controlling the maximum slant angle of an oscillating plate integrally with a swash plate, is provided in a variable capacity oscillating plate type compressor for refrigerant R-12. CONSTITUTION:The maximum slant angle of an oscillating plate 7 is regulated integrally with a swash plate 6 by a maximum slant angle regulating means so as to be capable of realizing the maximum compressing capacity suitable for refrigerant R-22. The maximum slant angle regulating means is provided with a projected piece or a stopper 201 at the side of a rotor for the swash plate 6 so as to be faced to a rotor 5. The stopper 201 is constituted so that the stroke of a piston becomes maximum when the projected end of the stopper 201 is abutted against the rotor 5 and according to this method, the maximum capacity of a compressor may be regulated so as to be capable of realizing the maximum compressing capacity suitable for the refrigerant R-22.
