ABSTRACT:
A variable capacity type swash plate compressor includes a novel hinge means. The hinge means includes a supporter arm, a main guide pin, and an auxiliary guide pin. The supporter arm is disposed on the rotor projectably therefrom toward the swinging swash plate, and has a main guide hole extending perpendicularly with the driving shaft. The main guide pin is inserted rotatably into the main guide hole. The auxiliary guide pin is inserted slidably into a hole, formed in one of the main guide pin and the swinging swash plate, perpendicularly with the main guide pin at one end, and it is fixed to another one of the main guide pin and the swinging swash plate at the other end. With the hinge means, the top clearances of the pistons can be always maintained virtually uniformly, and the moments resulting from the compression reactive forces can be inhibited from interfering with the discharge capacity control. Additionally, the compressor can attain the reduction in the manufacturing costs.
