Abstract
A variable capacity swash-plate-type refrigerant compressor incorporating therein single-headed pistons reciprocating in the cylinder bores to compress refrigerant gas, a drive shaft rotatably supported and driven by an external drive source, a swash-plate element mounted around the drive shaft and rotated by the drive shaft so that the rotation of the swash-plate element causing the reciprocation of the single-headed pistons, and a hinge mechanism arranged between the drive shaft and the swash-plate element to permit the swash-plate element to change its angle of inclination with respect to the axis of rotation of the drive shaft to thereby adjustably change the delivery capacity of the compressor, the swash-plate element being constituted by a swash-plate-body member made of an aluminum alloy material and functioning as a sliding contact member cooperating with the single-headed pistons via shoes, and a guide-bracket member made of an iron based material and functioning as a hinge mechanism forming member. The swash-plate-body member and the guide-bracket member are connected together by press-fitting and prevented, by a rotation-preventing unit, from being relatively rotated against one another.
