ABSTRACT:
An improved lubricating structure of a compressor is disclosed. A swash plate is tiltably supported on the drive shaft for an integral rotation therewith. A plurality of pistons are operably coupled to the swash plate. The rotation of the swash plate is converted to a reciprocal movement of each piston in an associated cylinder bore to compress and discharge gas that contains oil. A clearance is defined by the cylinder bore and the piston enabling the compressed gas to flow out from the cylinder bore to the swash plate. The swash plate has an operation area that receives greatest compression load based on reaction force of the compressed gas acting on the piston when the swash plate rotates. The swash plate has at least one bore for attaching the swash plate to a jig when the swash plate is ground during its manufacturing process. The bore is arranged to allow the gas flow out to the swash plate from the cylinder bore through the clearance to flow to the operation area.
