Abstract:
A pressure management apparatus including a housing (30) defining a fluid communication passage between first and second fluid ports (46, 48). A poppet (40) is disposed in the housing and is movable between first and second positions. The first position prevents fluid communication between the first and second fluid ports, and the second position permits fluid communication between the first and second fluid ports. The poppet includes a portion (75) translatable along an axis relative to the housing. A member (78) is fixed with respect to the housing and is associated with the portion of the poppet. Spring structure (72) is associated with the portion of the poppet. The spring structure is constructed and arranged to engage and bias the portion of the poppet to frictionally engage a portion of the member to create a dashpot damping of resonance of the poppet in the second position.
