Abstract (en)
[origin: EP1455143A1] The present invention provides a control device of a variable displacement compressor and a variable displacement control device of a refrigerating cycle, capable of providing optimal responsiveness and stability under different conditions, by adopting a structure in which a control chamber pressure is controlled with a control valve electrically controlled by a control signal provided from the outside without using a pressure sensitive member. The present invention is adopted in conjunction with a variable displacement compressor 3, the discharge capacity of which is controlled through an adjustment of a crank chamber pressure achieved by electrically controlling a pressure control valve that enables a pressure supply from a discharge space 27 to a crank chamber 24 and also a pressure release from the crank chamber 24 to a suction space 26 with a control signal provided from the outside and adjusts a gain in an arithmetic expression used to calculate the control signal in correspondence to a value representing a physical quantity that affects the air conditioning state. <IMAGE>
