  • Check valve controlled by differential pressure
    Patent number: 6390121
    Abstract: A check valve (4) controlled by differential pressure, preferably in form of a disk valve, having a closing element (5) that impacts a valve seat (8) with a force by means of an elastic (resilient) element, preferably a closing spring (6). The closing element (5) is provided with an additional mass (11), which is larger in its amount than the mass of the closing element (5) itself to dampen the closing shock in a manner whereby the closing element (5) does not rebound even once or several times and also to dampen the opening shock of a valve of this type as a matter of course.
