Abstract
A mechanism for drawing in refrigerant to front compression chambers (28a) of a double-headed piston type compressor differs from a mechanism for drawing in refrigerant to rear compression chambers (29a). More specifically, the mechanism for drawing in refrigerant to the front compression chambers (28a) include suction valves (18a) configured by flap valves. The mechanism for drawing in refrigerant to the rear compression chambers (29a) is configured by a rotary valve (35). Thus, pulsation of the compressor is reduced, so that the generation of noise is suppressed. As a result, a quiet compressor is achieved.
