ABSTRACT:
In a variable displacement wobble plate type compressor, first, second and third connecting passages are defined. The first connecting passage fluidly connects a bellows chamber in which a bellows is installed with a suction chamber to which refrigerant from an evaporator is returned. The second connecting passage fluidly connects a discharge chamber and a crank chamber through a valve port. The discharge chamber is a chamber from which compressed refrigerant is discharged and the crank chamber is a chamber in which a wobble plate is operatively disposed. The bellows installed in the bellows chamber changes its volume in accordance with a pressure in the bellows chamber. A control valve controls the valve port in response to the volume change of the bellows. The third connecting passage is a passage which fluidly connects the suction passage and the crank chamber without using the bellows chamber as a part thereof.
