  • Self-sealing valve
    Patent number: 6976669
    Abstract: Shut-off valve, composed of a container (3) provided with valve seat (4), and also a valve body (2, 22, 42) that can be moved through the opening bounded by the valve seat (4), in order to provide a seal. The valve body (2, 22, 42) is provided with a conical or spherical shut-off edge and is connected to the container (3) by way of a flexible connecting part (5). This makes it possible to move the valve body (2, 22, 42) laterally, in other words perpendicular to the direction of closing, and in this way achieve an opening of the shut-off valve. The container (3) can comprise any construction known in the prior art.
