ABSTRACT:
A variable capacity single headed piston, swash plate type compressor provided with a rotation-to-reciprocation conversion mechanism having a swash plate rotated by a drive shaft and formed with annularly extended engaged portions on opposite faces thereof, a pair of shoes located between the swash plate and each of the single headed pistons, each shoe having formed therein an engaging portion circumferentially slidably engaged with one of the annular engaged portions of the swash plate, and a spherical face to be in a displaceable and turnable contact with a cylindrical support wall of a radial recess of each piston and permitting a passage of the swash plate during the rotation thereof. The engagement and contact of the shoes with the swash plate and the pistons provide the respective pistons with an accurate and stable axial support, to thereby prevent a local abrasion of the single headed pistons.
