  • Check valve
    Patent number: 8776831
    Abstract: A check valve (10), including a valve membrane (12), which includes an umbrella-like closing body (14), which in a closed position abuts a housing body (5) in such a way that the closing body prevents the passage of a medium through passage holes (26) provided in the valve body (16), the closing body lifting off the housing body in an open position in order to allow a medium to pass through the passage holes. In the open position and/or closed position the closing element is clamped between the valve body and the housing body at least at one point (31, 32).
