Abstract
A one-way valve includes a plate and a flexible vane. The plate has a vent opening of a first size and shape. The plate has a first curvature. The flexible vane has a second curvature distinct from the first curvature. The vane is fixed to the plate in a manner facilitating the deflection of the vane between an open position and a closed position. The vane is in a bent condition in the closed position. The vane conforms to the first curvature of the plate over the vent opening, and covers the vent opening in the closed position. The vane is elastic throughout a range of deflection associated with the vane moving between the closed position and the open position.
