ABSTRACT:
A compressor has a swash plate tiltable between maximum and minimum inclining angles with respect to a plane perpendicular to an axis of a drive shaft according to a difference between pressures in a crank chamber and a suction chamber. An internal gas passage includes the crank chamber, the suction chamber and a discharge chamber. The internal gas passage is connected to an external circuit separately provided from the compressor. The rotation of the drive shaft is converted to a reciprocating movement of a piston to vary a capacity of a cylinder bore. The piston compresses a gas supplied from the external circuit to the internal gas passage and discharges the gas to the external circuit. A inhibiting apparatus inhibits the circulation of the gas through the internal gas passage and the external circuit when the swash plate is located between the minimum inclining angle and a first inclining angle. The first inclining angle is greater than the minimum inclining angle of the swash plate.
