  • Patent number: 4690296
    Abstract: A non obstructing, flap type valve for a circular conduit is defined as a right angle section from a cylinder wall of the same diameter. A mating, right angle section taken from the end of the circular conduit defines the valve seat. The valve is end mounted and pivots from a closed sealing configuration to an open, free flow position. A flattened rod cooperates with a cam surface to lock the valve in the closed position, or a bias spring may maintain the valve closed.
