Abstract:
A seal for a poppet valve of an integrated pressure management apparatus, the poppet valve being movable between an open position permitting fluid flow through an aperture in a housing and a closed position preventing fluid flow through the aperture, the seal comprising:an annular body surrounding an axis and having first and second sealing surfaces, the first sealing surface being adapted to be fixed to the housing and surround the aperture, and the second sealing surface adapted to confront the poppet valve; and an annular lip projecting from the second sealing surface and adapted to be resiliently deformed by the poppet valve at the closed position, the annular lip separating from the poppet and projecting obliquely toward the axis in the open position, and the annular lip including an annular tip at a distal end with respect to the annular body, the annular tip being adapted for scrapingly engaging the poppet valve as the poppet valve moves toward the closed position, wherein the annular tip contracts toward the axis as the poppet valve moves toward the closed position.
