    摘要: A variable displacement compressor which has a suction chamber (3a), a discharge chamber (3b), and a crank chamber (2a). The displacement of the compressor is controlled by supplying refrigerant to the crank chamber (2a) from the discharge chamber (3b) via a pressurizing passage (31) and releasing the gas into the suction chamber (3a) via a pressure releasing passage (30). An increase in the pressure in the crank chamber (2a) decreases the displacement, and a decrease in the pressure in the crank chamber (2a) increases the displacement. A displacement controlling structure of the compressor includes an electromagnetic valve (20) which alters the size of an area of the pressurizing passage (31). A computer (Ca) controls the electromagnetic valve (20) in accordance with commands to alter the displacement. The computer (Ca) enlarges the opened area of the pressurizing passage (31) by controlling the electromagnetic valve (20) in response to commands to reduce the displacement.
