The invention relates to a sanitary single-lever mixer unit (1) having a control cartridge (5) arranged in an accommodation area (4) of a fitting housing (2) in a known manner. Using an upwardly projecting adjustment shaft (17), at least one control element controlling a water flow can be moved in the control cartridge (5). An annular cover part (10) partially covers the accommodation area (4) toward the top and, viewed from the top, has a convex, annular outer spherical cap surface (14). The operating handle (18) of the single-lever mixer unit (1) comprises a cap (18a), which extends over the cover part (10) and on the bottom side thereof is provided with a seat (19) into which the upper end region of the adjustment shaft (17) can be inserted. Viewed from below, the bottom side of the cap (18a) is also provided with a concave, annular spherical cap surface (20). Said spherical cap surface (20) glides on the upper edge of a sliding ring (16), which is mounted to the cover part (10) and upwardly extends beyond the same. Thus, in all positions of the operating handle (18), the spherical cap surfaces (14, 20) of the cover part (10) and the cap (18a) remain at a slight distance from one another. The gap created between the cover cap (18a) and fitting housing (2) and/or cover part (10) can be kept to a very small size. |
