<p>In a sanitary mixing valve, consisting of a cylindrical valve housing (3), a valve seating disc (2), with an inlet and outlet opening (21, 22) for the medium flowing in and out, a control disc, supported in an adjustable manner on the valve seating disc (2) with an overflow channel (11), it being possible for the inlet openings to be made to overlap with the outlet opening by means of the overflow channel (11) and the control disc being provided to introduce the control parameter by means of a control lever (34) which is supported in the valve housing (3) such that it can rotate and tip, for improvement and especially in order to reduce the external diameter of the mixing valve it is proposed that the overflow channel (11, 13) be designed approximately in the form of an ellipse at least on the side facing the valve seating disc (2), the major axis (111) of the ellipse shape forming the radial displacement axis of the control disc (1) and the major apex, which interacts with the inlet openings (22), corresponding at least approximately to an arc whose centre coincides with the centre of an inner arc (211) of the inlet openings (21) when the axis of symmetry (212) to the inlet openings (21) of the valve seating disc (2) coincides with the major axis (111, 131) of the overflow channel (11, 13) and the mixing valve is in the closed position. …<IMAGE>… </p> |
