US Patent 9713693 Exhaust valve and method of manufacture therefore

A valve (20) is provided that selectively controls flows of fluid through a valve opening (50). The valve (20) includes an elastically resilient valve member (54) that is seated in a member pocket (52) with a valve flap (76) that covers the valve opening (50). The valve flap (76) substantially prevents flows of fluid in one direction through the valve opening (50), but permits flows of fluid in the other direction.
