Abstract
The specification discloses a seal member for selectively completing a fluid passageway defined between an upstream member and a downstream member separated by an intermediate space, the seal member comprising an elongate stem portion dimensioned to be movably positionable in an opening defined through the upstream member between opposite first and second surfaces thereof, the elongate stem portion having provided at one end thereof a resiliency deformable, radially-extending flange and at the other end thereof a sealing face, and a fluid passageway defined through the stem portion between the flange and the sealing face. The flange is deformable under fluid pressure to increase the area of contact between the flange and the first surface of the upstream member and to simultaneously move the stem portion within the opening defined in the upstream member so as to bring the sealing face into sealing contact with an opposing surface of the downstream member across the intermediate space.
