Abstract:
A sanitary fitting performed as a single-lever mixer having a housing part (5) and an exit part (6) containing the exit channel (7), wherein in the housing part (5) a mixer tap (11) for mixing cold and warm fluid and for controlling the flow rate is positioned and is actuatable between a closed final position and an opened final position by a control rod (10) connected to an actuating lever (8), wherein an electrically controllable valve (14) is fitted downstream of the mixer tap (11) by the means of which a fluid emanating from the mixer tap (11) before entering into the exit channel is guided, wherein the electrically controllable valve (14) by the means of a control electronic circuit (39) is connected to a proximity sensor (37) and, wherein the electrically controllable valve (14) additionally can be controlled mechanically by means of the actuating lever (8) via the control rod (10), wherein a lever arrangement (12) is provided between the control rod (10) and the electrically controllable valve (14) which mechanically is adjusting the electrically controllable valve (14) in such a waya) that in the closed end position of the mixer tap (11) or within a first pivot range (I) of the actuating lever (8) following said end position respectively, in spite of electric control signals applied to the electrically controllable valve (14) the valve (14) is remaining closed,b) that in the completely opened final position of the mixer tap (11) or within a third pivot range (III) preceding said end position the valve (14) is remaining opened, too, in spite of electric control signals applied to the valve (14) and,c) that within a second pivot range (II) of the actuating lever (8) being positioned between the first and the third range the electrically controllable valve (14) is remaining closed and is opened only by the means of activation by the proximity sensor (37).
