Claim:
A pressure management apparatus comprising: a housing defining a fluid communication passage between first and second fluid ports, a poppet disposed in the housing and being movable between first and second positions, the first position preventing fluid communication between the first and second fluid ports, and the second position permitting fluid communication between the first and second fluid ports, the poppet including a portion translatable along an axis relative to the housing, a member fixed with respect to the housing and associated with the portion of the poppet, and spring structure associated with the portion of the poppet, the spring structure being constructed and arranged to engage and bias the portion of the poppet in a direction generally transverse with respect to the axis to frictionally engage a portion of the member to create a dashpot damping of resonance of the poppet in the second position, wherein the spring structure is a metal structure having a portion secured to one of the housing or the member, with a free end of the metal structure engaging the portion of the poppet.
