ABSTRACT OF THE INVENTION A deformable sealing member is disposed between two surfaces such that a space-is provided to at least one side of such sealing member. A smaller space may be provided to a second side of the sealing member. The sealing member is conformed to contact both surfaces. A pressure coming from the direction of the greater space between the two surfaces will cause the sealing member to deform into greater compliance with the two surfaces. However, should pressure reverse and approach the seal from the opposite direction the seal will distort into the area of greater space thereby causing the seal to break contact with one of the surfaces and for such pressure to vent past the seal.
