Control valve in variable displacement compressor and method of manufacturing the same |
摘要 |
A control valve for a variable displacement compressor is provided. A retainer cylinder in the control valve includes a first cylindrical member made of non-magnetic material and a second cylindrical member having a bottom portion made of magnetic material. A shim is intervened a bottom surface of a plunger and inner bottom surface of the second cylindrical member. The retainer cylinder has good magnetic permeability between a coil and the plunger, even though the wall of the cylinder thickens to improve the withstanding pressure to internal refrigerant pressure.
