<p>In a control disc valve with at least two control discs, the linear movement of one of the control discs, which is involved with a variation in quantity of the medium to be regulated, is prevented by a special brake. For this purpose the movable control disc itself is inserted in a closed chamber so that it divides the latter into two partial chambers. The latter are connected to each other by way of a displacement path. The closed chamber is filled with a fluid medium of suitable viscosity. If the control disc moves in a linear manner for varying the quantity of the medium passing through, it operates within the closed chamber in the manner of a piston and displaces the fluid medium by way of the displacement path from one partial chamber to the other. Active lubrication of the sliding surfaces of the control discs can be associated with this at the same time. (FIG. 1).</p> |
