ABSTRACT:
A poppet valve assembly is provided. The preferred poppet valve assembly comprises a valve seat, valve head member and actuation arrangement. In the preferred embodiment, the valve head member comprises a flexible seal member and backing member, oriented such that the flexible seal member is positioned between the valve seat and the backing member. In use, the backing member is driven toward the valve seat, trapping the flexible seal member therebetween. The seal member engages the valve seat and is simultaneously deflected backward toward the backing member, which limits deformation of the seal member.
