ABSTRACT:
A rotary compressor includes a fixed side and a movable side that is eccentrically movable relative to the fixed side. The movable side moves in response to operation of a drive mechanism, which rotates a drive shaft. The fixed side has a main bearing formed as a unitary part. A cylinder may serve as the movable side, which is coupled through an eccentric part to the drive shaft. The drive shaft is supported by the main bearing. With such an arrangement, a ring-shaped piston may serve as the fixed side, which is formed integrally with the main bearing in a front head.
