Abstract

An introduction passage (31) of rotary valve (35, 36) has outlets (312, 313) for feeding out refrigerant in a suction pressure zone (142) toward each of compression chambers (271, 281). A switch portion in a shutoff state shuts off a portion (142) of the suction pressure zone within a compressor (10) from the outlets (312, 313) of the introduction passage (31). The switch portion includes a valve body (42), a working pressure chamber (412), and a working pressure applying portion (48, 67-68). The working pressure chamber (412) introduces a working pressure that is applied to the valve body (42) so as to arrange the valve body (42) at a communication position. The pressure in the suction pressure zone (142) acts against the pressure in the working pressure chamber (412) through the valve body (42).
