ABSTRACT:
A single headed swash plate type compressor including, a housing with a crank chamber and cylinder bore, pistons arranged in cylinder bores, and a swash plate driven by a drive shaft. Each of the pistons has at one end thereof a bearing having axially spaced first and second bearing portions and an axially extending third portion interconnecting the first and second bearing portions. Shoes are slidably arranged between the swash plate and the first and second bearing portions for converting rotational movement of the swash plate into reciprocal movement of the pistons. An oil communication hole is arranged in and extends through the second bearing portion for fluid communication between the groove of the second bearing portion on the side remote from the cylinder bore and the crank chamber.
