Definitions

• the invention relates to an insert for a single-lever mixing valve with a stationary outer sleeve, with an inner sleeve rotatably mounted in the outer sleeve, with a rotatable with the inner sleeve and radially movable relative to the inner sleeve, with a transversely pivotally mounted in the inner sleeve, inside in the driver engaging and externally actuated spindle, and with flat abutting and breakthrough disks, one of which is designed as an inlet disk and on the outer sleeve, another as a control disk and is attached to the driver.
• Inserts for single-lever mixing valves of the aforementioned type are known (DE 26 01 952 AI; DE 27 39 587 C2).
• the known inserts have two disks, namely the inlet or fixed disk and the control disk.
• Your outer sleeve consists of a closed Cylinder; Warm and cold water inflow and mixed water outflow take place via its end facing away from the spindle. The opening and closing of the valve and the mixing of cold and hot water take place in the area of the discs on the same level.
• the mixed water must be redirected on the side of the control disk facing away from the fixed disk and be guided through the disks again. This results in small opening cross sections and large turning and sliding surfaces.
• the invention seeks to remedy this.
• the invention has for its object to provide an insert for a single-lever mixing valve of the type mentioned so that large openings and small rotating and sliding surfaces are possible.
