Abstract

See full text

A poppet valve with an integrated dampener is disclosed. In some embodiments, the valve includes a poppet guide with a stem and a hollow poppet is disclosed. The hollow poppet receives the poppet guide stem therein, thereby defining an internal cavity. The poppet is movable relative to the poppet guide to adjust the volume of the internal cavity. The poppet is also moveable relative to a valve seat between a seated position and an unseated position. The poppet may include a body with a seal groove and an elastic seal disposed within the seal groove. The seal is configured to engage the valve seat prior to the poppet body when the poppet moves toward the seated position. The valve may include a poppet guide pivot system that enables pivoting of the poppet guide and the poppet relative to an axial centerline of the valve.
