Abstract
An integrated pressure management apparatus, system and method for minimizing resonance of a poppet. A housing defines a fluid communication passage between ports. The housing includes a first portion, which extends along an axis, and has a first surface parallel to the axis. A poppet is movable between a first configuration that prevents fluid communication between the ports, and a second configuration that permits fluid communication between the ports. The poppet includes a second portion. The second portion is translatable along the axis relative to the housing, and includes a tubular stem that has a second surface parallel to the axis. The second portion nests with the first portion so as to define a gap between the first and second surfaces. The first and second portions define a chamber, and the gap restricts fluid flow between the fluid communication passage and the chamber.
