Control valve in variable displacement compressor and method of manufacture

摘要

A control valve (49) for a variable displacement compressor. The control valve (49) has a valve body (64) for regulating gas flow. A bellows (70) actuates the valve body (64) through a first rod (72) in accordance with an operating pressure introduced to a pressure sensing chamber (68). A solenoid (62) biases the valve body (64) through a second rod (81) with a force based on the level of an electric current supplied to the solenoid (62). The cross-sectional area (B2) of the second rod (81) is no smaller than the cross-sectional area (B1) of a valve hole (66) of the control valve (49). <IMAGE>
