<p><P>PROBLEM TO BE SOLVED: To provide a variable displacement compressor restraining refrigerant leakage by arrangement of a capacity control valve, reduction in the noise reducing function, and the deterioration in productivity. <P>SOLUTION: This variable displacement compressor has a delivery chamber 120, a suction chamber 119, a crankcase 105 and a plurality of cylinder bores 101a partitioned and formed in a housing, a piston 117 arranged in the cylinder bores, a driving shaft 106, a motion changing mechanism having an inclination variable swash plate 107 and converting rotation of the driving shaft into reciprocating motion of the piston, the capacity control valve 200 in a communicating passage of the delivery chamber and the crankcase, and an orifice 103d in a communicating passage of the crankcase and the suction chamber, and adjusts a stroke of the piston by changing crankcase pressure by the capacity control valve. The suction chamber is arranged on an extension line of the driving shaft, and the delivery chamber is arranged outside in the radial direction of the suction chamber. The capacity control valve has a suction chamber pressure sensitive part on one end side, a bursting part to the crankcase on the other side and a delivery pressure introducing part between the pressure sensitive part and the bursting part, and is stored in the housing, and is not exposed outside the housing. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
