ABSTRACT:
A valve assembly which allows air to pass in one direction in a substantially resistance-like manner while preventing the flow of air in the opposite direction. The valve assembly includes a hollow conduit having 1) an interior peripheral surface which defines a flow passage, 2) an exterior peripheral surface, and 3) a radial passage extending through the conduit for communicating the flow passage with the exterior peripheral surface. The valve assembly also includes a continuous recess formed in the exterior peripheral surface of the hollow conduit in the region of the radial passage and a valve positioned within the recess in the exterior peripheral surface and proximate to the radial passage. The valve includes a pressure ring portion and a continuous lip portion pivotably connected to said pressure ring.
