Abstract
A swash plate type compressor comprises a cylinder block cooperating to form therein a compartment accommodating therein a swash plate and also serving as a suction chamber of the compressor, and a drive shaft rotatably supported in the cylinder block and having formed therein an axial discharge passage connecting front and rear discharge chambers. The compressor further includes a pair of front and rear rotary type suction valves mounted on the drive shaft for rotation therewith and fitted in bores formed centrally in the cylinder block such that one axial end thereof is exposed to suction pressure and the other end to discharge pressure of the refrigerant gas. Each suction valve has formed therein a passage which is in constant communication with the swash plate compartment and is operable to bring its passage in communication successively with fluid working chambers in synchronism with the rotation of the drive shaft. The drive shaft is formed with a lubricating oil hole extending radially from its central discharge passage to its outer periphery and directed to feed lubricating oil toward the sliding contact surfaces between the suction valve and its accommodation bore.
