Abstract
A check valve includes a housing, a flap, a hinge, at least one post, and at least one tubular bumper. The hinge allows the flap to rotate relative to the housing between a fully open position and a closed position. The at least one post is disposed at or near the periphery of the housing supporting the hinge and extending axially relative to the housing from the housing. The at least one tubular bumper is movable with the flap and configured to contact the at least one post when the flap pivots to the fully open position.
