Abstract

A scroll compressor includes a housing (10), a fixed scroll (26), a movable scroll (28) both disposed in the housing (10), and an injection passage (52) through which medium-pressure refrigerant is introduced into a compression chamber (30B). The scroll compressor further includes a selector device (60) connecting the compression chamber (30B) to the injection passage (52) or disconnecting the compression chamber (30B) from the injection passage (52) with the change of the pressure or the temperature of the refrigerant in the suction chamber (38).
