发明名称 CONTROL VALVE FOR VARIABLE DISPLACEMENT COMPRESSOR
摘要 The present invention relates to a control valve for a variable displacement compressor to maintain the control characteristics under a high pressure environment. According to one embodiment of the present invention, a control valve includes a shaft (68) that transmits the solenoidal force to a valve element. A solenoid (3) includes: a bottomed sleeve (52) into which the pressure of refrigerant is introduced; a core (50) coaxially fixated to the sleeve (52); a plunger (54) accepted in the bottom of the sleeve (52) to be displaceable integrally with the shaft (68) in a direction of axis line; a spring (40) that applies the biasing force in a valve opening direction to the shaft (68); a spring (78) that applies the biasing force in a valve closing direction to the plunger (54); and a shaft support member (76) which is press-fitted such that the shaft support member (76) is fixated to an inner wall of the sleeve (52) near its bottom portion. The spring (78) is set between the shaft support member (76) and the plunger (54). A pressure is applied to the shaft support member (76) by deforming the bottom portion of the sleeve (52) in the direction of axis line, so that the press-fitting position of the shaft support member (76) relative to the sleeve (52) can be adjusted.
