Variable displacement compressor having piston anti-rotation structure

摘要

A variable capacity swash plate type compressor (10) incorporates an anti-rotation structure (60) formed on each piston (52). Each piston (52) is disposed in a cylinder (14) of a cylinder block (12). The cylinder block (12) is disposed in a crankcase (18). The anti-rotation structure (60) restricts rotation of a piston (52) within a cylinder (14) by cooperating with an inner surface of the crankcase (18).
