Abstract (en)

A rotary valve (71) of a compressor is formed with a release path (71e) configured to release a high pressure residual refrigerant which have not been discharged in a compression and discharge stroke from one cylinder bores (B 1 ) which is in an initial stage of its suction stroke to other cylinder bores (B 3 , B 4 ) having a lower pressure than the one cylinder bores (B 1 ). The release path (71e) is formed with an inlet (71f), a first outlet (71g), a second outlet (71h), and a communication part (71k) connecting the inlet and the outlets. During a time period when the inlet (71f) of the release path (71e) is connected to the cylinder bore (B 1 ) which is in a initial state of its suction stroke, the first outlet (71g) is connected to the cylinder bore (B 3 ) next to, in an opposite direction to the rotational direction, the cylinder bore (B 4 ) which is 180 degree opposite to the cylinder bore (B 1 ), and then, the second outlet (71h) is connected to the cylinder bore (B 4 ) which is 180 degree opposite to the cylinder bore (B 1 ).
