Abstract:
A seal for sealing system pressure from a housing gap between a first and a second housing member, the first member having a first sealing surface at a first member side of the gap and the second member having a second sealing surface at a second member side of the gap, the seal comprising:a first extrusion-resistant, flexible sealing component having a vault-shaped cross section, said first component having a first leg which can cooperate with the first sealing surface and a second leg which can cooperate with the second sealing surface; and a second, deformable sealing component disposed on said first sealing component, said second sealing component being structured and dimensioned to press against the first and the second sealing surfaces in response to the system pressure to seal the gap, wherein said first leg and said second leg subtend an angle at a side of said first sealing component facing said second sealing component, said angle decreasing in response to system pressure until said first leg seats flatly against said first sealing surface and said second leg seats flatly against said second sealing surface.
