A slant plate type compressor (10) having a lubricating mechanism for a piston assembly (71) is disclosed. The compressor (10) includes a housing (20) having a cylinder block (21) provided with a plurality of cylinders (70) and a crank chamber (22) adjacent the cylinder block (21). A piston (72) slides within each cylinder (70) and is reciprocated by a wobble plate (60) driven by a cam rotor (40) mounted on a drive shaft (26). Each of pistons (72) is connected to each of periphery located outer ends of the wobble plate by a connecting rod (73). The piston (72), at least one piston ring (81) disposed on an outer peripheral surface of the piston and the connecting rod (73) form the piston assembly. The piston (72) and connecting rod (73) are connected by a ball-socket connection (73a). During the compression stroke, the lubricating mechanism having a conduit (74) formed in the piston supplies a lubricating oil to a gap (g) created within the ball-socket connection (73a) from the cylinder chamber (70D) together with the pressure dropped refrigerant gas. |
