Abstract:
In a pressurized gas flow control device including a pressurized gas control body to which is provided pressurized gas from a source of pressurized gas under pressure, and means for selectively connecting or disconnecting a pressurized gas flow connection to the pressurized gas control body, the improvement comprising a pressure relief device for relieving pressurized gas pressure within the pressurized gas control body before disconnecting the pressurized gas flow connection, the pressure relief device comprising a valve member movable for operation along an axis of movement within a valve member chamber in which the valve member is juxtaposed between a rigid surface of the chamber and a seat for the valve member, the seat communicating exteriorly of the pressurized gas control body, the chamber communicating with the pressurized gas control body for receiving pressurized gas pressure within the pressurized gas control body, the valve member being formed at least in part of a resilient material contacting the rigid surface and urging the valve member along said axis in a direction against said seat for providing a sealing relationship, the resilient material being compressible, the valve member being selectively shiftable by compressing of the resilient material along said axis toward the rigid surface for unseating of the valve member from the seat to vent pressurized gas pressure to exteriorly of the pressurized gas control body.
