Abstract
The valve having a casing with an inflow and outflow connection which can be separated from or connected to one another by means of a movable valve member which can be brought to bear against a valve seat, the movable valve member being provided with a damping mechanism which prevents blow-like, rapid actuation at least in the closing direction. The damping or restraining mechanism consists of a displacer which is mechanically connected with the valve member, said displacer, during the movement of the valve member, slowly changing its volume through a narrow passage or leak. A non-return valve allows a more rapid movement in the opposite direction.
