<p><P>PROBLEM TO BE SOLVED: To provide a compression capacity control device of a refrigerating cycle with such a high response that, when the electromagnetic force of an electromagnetic control valve is changed, a compression capacity rapidly reaches a predetermined value without time delay. <P>SOLUTION: A capacity control valve 20 communicating and interrupting a pressure regulating chamber 12 with and from a discharge chamber 4 or a suction chamber 3 is installed to keep a predetermined pressure difference between at least one of a pressure in the pressure regulating chamber 12 and a pressure in the suction chamber 3 and a pressure in the discharge chamber 4. Since the pressure difference is changed by changing the electromagnetic force of the capacity control valve 20, the discharge amount of a refrigerant can be controlled. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
