Abstract
An on-off valve that operates between an open position and a closed position, particularly with high-pressure working fluids. has a valve body that defines a valve cavity. A valve poppet is slidably mounted within the valve cavity. A bushing is mounted with respect to the valve body and divides the valve cavity into a first chamber and a second chamber. One end of the valve poppet is positioned within the first chamber and an opposite end of the valve poppet is positioned within the second chamber. A spring urges the valve poppet into the first chamber. An actuating pin is slidably mounted with respect to the valve body. In the closed position, the actuating pin seals the passage of the valve poppet. An actuator is used to operate the actuating pin between the open position and the closed position of the on-off valve.
