A cutting process S cuts a wire into cut pieces each having a volume approximately equivalent to that of a desired shoe . A forging process S sequentially forges cut pieces with forging dies , and having three cavities , and respectively, and obtains a steel sphere . A finishing process S obtains a shoe-shaped material from the steel sphere without a heat treatment, and carries out a heat treatment to the obtained material , thereby to obtain a shoe for a compressor.

Method of manufacturing shoe for compressor

Compressor scrolls are made of an aluminum alloy containing 4.0 to 5.0% by weight of Cu, 9.0 to 12.0% by weight of Si, 0.5 to 1.5% by weight of Mg, and 0.6 to 1.0% by weight of Fe. The scrolls are manufactured using a high speed die casting method.

Scroll type compressor and method for manufacturing the same

A swash plate compressor especially suited for automotive vehicles. The inner housing may be moved in the rear housing in the front and rear direction, as the occasion may demand, for adjusting the compression capacity or performance of the compressor. A partition wall is projectingly projected at the front side of the inner housing for defining an inner or discharge chamber and an outer or suction chamber. A plurality of clamp bolts for fixedly clamping together a rear cylinder block and the rear housing are passed through said suction chamber. The rear wall of the inner housing is formed with an annular thin-walled portion lesser in thickness than the valve plate on the front surface of said inner housing. By the function of said thin-walled portion, the inner housing may be flexed readily to absorb valve plate strain.

Swash plate compressor

A piston for a swash plate type compressor is disclosed in which a plurality of similar pistons are reciprocated to provide a compressing operation by means of a swash plate which is mounted on the drive shaft and rotated in the compressor cylinder. The piston comprises a piston main body or blank made of aluminium or aluminium alloy, and a coating layer applied to the overall surface of the piston blank except central portions of both outer end faces of the blank, said coating layer being of ethylene fluoride or a copolymer of ethylene fluoride and a vinyl compound, the heat conductivity of which is lower than that of the piston blank.

Method of manufacturing a piston for a swash plate type compressor

A swash plate type compressor, having a swash plate fixedly and slantingly secured to a drive shaft and also secured to pistons in such a manner that the pistons reciprocate as the swash plate rotates, has piston webs which have a sliding outer surface and a relief inner surface. A clearance exists between a circumferential surface of the swash plate and the relief surface which creates a wedge effect which, in turn, produces a lubricating film pressure that substantially reduces wear between the circumferential surface of the swash plate and the sliding surface.
