ABSTRACT:
A slant plate type compressor having a lubricating mechanism for a piston assembly includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber adjacent the cylinder block. A piston slides within each cylinder and is reciprocated by a wobble plate driven by a cam rotor mounted on a drive shaft. Each piston is connected to the outer periphery of the wobble plate by a connecting rod. The piston has at least one piston ring disposed on its outer peripheral surface. The piston and connecting rod are connected by a ball-socket connection. During the compression stroke, the lubricating mechanism, which has a conduit formed in the piston, supplies lubricating oil from the piston chamber and the pressure reduced refrigerant gas to a gap created within the ball-socket connection.
