Single-lever mixing gear for a plumbing fixture

A single-lever mixing gear for a water fitting for dispensing water in a sanitary device, wherein the water fitting comprises a fitting member which is associated with the sanitary device and which has a device for actuating the single-lever mixing gear and the single-lever mixing gear containing a hot-water supply flow and a cold-water supply flow, devices for opening and closing the supply flows and for mixing and limiting the water streams and a closable mixed water outlet which is connected to the outlet in the fitting member of the sanitary device, wherein the single-lever mixing gear and the fitting member are spatially separated from each other, wherein the single-lever mixing gear can be actuated with the device for actuating the single-lever mixing gear via a direct mechanical connection or by an electrical drive, wherein the single-lever mixing gear contains a blocking member in the hot-water supply flow and a blocking member in the cold-water supply flow as devices for opening and closing the supply flows and for mixing and limiting the water streams, wherein the water being introduced through the blocking member in the hot-water supply flow and the water being introduced through the blocking member in the cold-water supply flow can be supplied as mixed water having a temperature which is predetermined by the position of the device for actuating the single-lever mixing gear to the blocking member as a device for opening and closing and for controlling the quantity of water to be discharged from the mixed water outlet of the single-lever mixing gear, wherein the device for actuating the single-lever mixing gear is mechanically connected to the three blocking members as devices for opening and closing or acts as a control of the electromotive drives of those devices, and wherein the blocking member in the hot-water supply flow and the blocking member in the cold-water supply flow can only be actuated together for proportionally opposing control of the quantity of the-water supply flow, and wherein the blocking member for blocking and controlling the quantity in the mixed water outlet can be actuated independently of the blocking member in the hot-water supply flow and the blocking member in the cold-water supply flow.
