ABSTRACT:
A compressor has an internal refrigerant gas passage selectively connected to and disconnected with an external refrigerant circuit separately provided from the compressor. The compressor has a reciprocable piston in a cylinder bore formed in a housing for compressing gas supplied from the external refrigerant circuit to the internal refrigerant gas passage. A drive shaft is rotatably supported by the housing. A swash plate is supported on the drive shaft for integral rotation with and inclining motion with respect to the drive shaft. The swash plate is movable between a maximum incline and a minimum incline. A disconnecting apparatus disconnects the internal refrigerant gas passage from the external refrigerant circuit when the swash plate is at its minimum incline. A restricting member restricts the amount of gas to be passed through the internal refrigerant gas passage in association with the disconnecting apparatus when the swash plate moves.
