WIPO Patent Application WO/2012/024560
Kind Code:
A3
Abstract:
A tip-resistant valve plug includes a valve head, first and second retention legs, and an anti-tip fin. The valve head includes a continuous partition defining a fluid barrier between a sealing side and an external side of the valve head. Each of the first and second retention legs extend from a leg base positioned at the sealing side of the valve head to a distal end of the retention leg. Each of the first and second retention legs include a plug catch configured to interfere with an inside diameter of a fluid flow orifice or a pressure relief spring. The respective distal ends of the retention legs are spaced apart from one another, and the anti-tip fin extends from the sealing side of the valve head in a direction of the respective distal ends of the retention legs.
