ABSTRACT:
A variable displacement compressor is provided. The compressor has a crankcase, a plurality of pistons, a swash plate, and a rotor assembly. The crankcase has a plurality of chambers for receiving a fluid. The plurality of pistons are disposed within the cylinder block and are configured for reciprocal movement within the plurality of chambers to pump the fluid. The swash plate is slidably coupled to the plurality of pistons and has a first hinge member extending from a surface of the swash plate. The first hinge member has a surface that has a cam profile. The rotor assembly has a rotor shaft and a rotor plate. The rotor plate has a second hinge member extending from a surface of the rotor plate, whereby the surface of the first member is configured to slide and rotate over the second hinge member forming a hinge about which the swash plate rotates.
