    • A service coupling (20) for use with either a push-type or a screw-type port valve of a charge port (22) is provided that includes a body portion (58) and an axially moveable valve housing (82). Axial movement of an actuator (70) permits both the selective axial movement of the valve housing (82) from a rearward position toward a forward position and the selective disengagement of the port valve (44) to open a flow path. In one embodiment the actuator (70) has a nose portion (356) that engages a threaded port valve, or axially moves a push-pin valve, to open a flow path. The operation is the same with either type of type of valve such that the user in not required to know which type of valve is present.
    • 提供了一种用于与充电口(22)的推式或螺旋型端口阀一起使用的连接件(20),其包括主体部分(58)和可轴向移动的阀壳体(82)。 致动器(70)的轴向运动允许阀壳体(82)从后部位置朝向前方位置的选择性轴向移动,并且选择性地分离端口阀(44)以打开流动路径。 在一个实施例中,致动器(70)具有接合螺纹口阀的鼻部(356),或者轴向移动推销阀以打开流路。 该操作与任何一种类型的阀门相同,使得用户不需要知道存在哪种类型的阀门。
