Abstract
A pressure management apparatus () includes a housing () defining a fluid communication passage between first and second fluid ports (). A poppet () is disposed in the housing and is movable between first and second positions. The first position prevents fluid communication between the first and second ports and the second position permits fluid communication between the first and second ports. The poppet includes a structure () translatable along an axis relative to the housing. At least a portion of the structure includes a permanent magnet (). A member () is fixed with respect to the housing and is associated with the structure. At least a portion of the member is of ferrous material such that the magnet is attracted to the member so that at least a portion of the poppet frictionally engages the member to create a dashpot damping of resonance of the poppet in the second position.
