ABSTRACT:
A hinge mechanism is provided for a variable capacity swash plate type compressor. The swash plate type compressor includes a housing having a plurality of cylinder bores, a crank chamber, a suction chamber, and a discharge chamber. A rotor is mounted on and rotatably fixed to a drive shaft and includes a first portion of a hinge mechanism. A swash plate, including a second portion of the hinge mechanism, is operatively connected to the rotor via the hinge mechanism and slidably mounted on said drive shaft to thereby change an inclination angle thereof in response to changes of pressure in the crank chamber. The first portion of the hinge mechanism includes a pair of support arms protruding from the rotor toward the swash plate, each of the support arms having a guide groove, and the second portion includes an arm having one end extending from the swash plate, and a pin means supported by the other end of the arm. The guide groove is formed in an inside surface of each support arm in such a manner that the guide grooves are opposed in parallel to each other, and the pin means is arranged to be slidably engaged with the guide grooves at end portions thereof so as to guide a movement of the pin means in the guide grooves.
