Abstract
In a control disc valve, which is intended particularly for sanitary use, a first control disc containing water inlet openings is arranged in a stationary manner. A second control disc, which contains a recess, for example a guide channel through which water flows, is able to move with respect to the first control disc. A movement brake is provided, which retards the closing movement of the second control disc at least in the region immediately before the complete closure of the valve. For this purpose a cylinder bore is located in the movable control disc, which bore communicates with the recess in the second control disc through which water flows. A damping piston moves in the cylinder bore. The piston is actuated by way of a plunger, which at the time of the movement of the control disc abuts against another part of the valve, in particular against the wall of the cartridge housing.
