Abstract

In the case of a sanitary single-lever mixer tap, the cover cap that closes the tap housing at the top rotates the operating lever around the axis (A-A), at which the temperature of the mixed water flowing out is changed. If the amount of mixed water changes, the operating lever moves linearly in relation to the cover cap. This ensures that, in order to improve hygiene, the surface of the cover cap, which is alternately released and covered by the operating lever, is kept as small as possible.
