摘要： An operating rod is subjected to a surface hardening heat treatment without a post finishing process which enhances a responsiveness of the operating rod by preventing powders from being attracted to a sliding surface of the operating rod. The capacitive control valve includes a solenoid rod portion communicating with a moveable core of the solenoid portion, an operating rod connected with the solenoid rod portion, the operating rod including a valve body used for opening or closing a control fluid passage hole, and a fixed core arranged opposite relative to the moveable core. The fixed core includes a guide hole defined therein which guides the operating rod through the guide hole in a freely moveable manner, the operating rod extending longitudinally through an internal bore. The operating rod being subjected to surface hardening treatment at a relatively low temperature that does not exceed 500° C.

摘要： A capacity control valve that implements an accurate pressure control of a valve body by preventing unwanted pressures from influencing on the valve body and that alters the function of a control chamber such that the pressure within the control chamber to which a control pressure is supplied can quickly be modulated. In the capacity control valve, a valve opening joint portion which is integral with a valve body can rapidly be disengaged from an engagement portion which is integral with a pressure sensing device, hence a quick lifting of the valve body so as to modulate the capacity or pressure in the control chamber. Also equating, exactly or approximately, the seal pressure receiving area of the valve body to the effective pressure receiving area of the pressure sensing device, and further to the pressure receiving area of an action face, or equating, exactly or approximately, the seal pressure receiving area to the pressure receiving area of an action face, yields only a desired pressure to act on the valve body.
摘要翻译：一种容量控制阀，其通过防止不必要的压力影响阀体来实现阀体的精确的压力控制，并且改变控制室的功能，使得控制室内施加控制压力的压力可以快速被调制。在容量控制阀中，与阀体一体的阀开口接合部分可以快速地从与压力感测装置成一体的接合部分脱离，从而快速提升阀体以调节容量或控制室内的压力。还将阀体的密封压力接收面积与压力感测装置的有效压力接收面积进一步等价于正好或近似的动作面的压力接收面积，或恰恰相当于或等于密封压力接收区域到作用面的压力接收区域，仅产生作用在阀体上的期望压力。
