ABSTRACT:
A swash plate type compressor incorporating therein a swash plate having an annular rail raised from each flat face thereof for providing a sliding-contact surface being in contact with sliding-contact surface portions of respective shoes which constitute a rotation-to-reciprocation conversion unit arranged between the swash plate and double-headed pistons reciprocating axial cylinder bores of the compressor. The sliding-contact surfaces of respective shoes bulge outward and have a radius of curvature "R" in the range of 800 through 1600 millimeters which is smaller than that of the conventional shoes of a swash plate type compressor, so that relatively large wedge shaped gaps are formed between the respective shoes and the swash plate to thereby stably and constantly hold lubricating oil.
