Abstract (en)
[origin: WO2004005787A2] 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.
