Embodiment Construction

[0024] figure 1 and figure 2 Only the upper region of the single-handled flow mixing unit is shown in , which is denoted by reference numeral 1 as a whole. The single-handle mixing unit includes an accessory housing 2 on which an outlet 3 is integrally formed. Exit 3 is only in figure 1 seen in and in figure 1 Only a part of outlet 3 is shown in . Inside the fitting housing 2 there is a receiving chamber 4 for a control cartridge 5 with at least one movable control element influencing the cold and hot water flow. The detailed construction of the control cartridge 5 is not relevant in this application and is therefore not described in detail. All that is known is that cold and hot water are delivered from below via two supply lines 6 (only one of which can be seen in the drawing) to the control cylinder 5, on the bottom side of the control cylinder 5 the mixed water is produced and flows To the outlet 3 , the temperature of this mixed water depends on the position of the...

Abstract

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.

Description

technical field [0001] The present invention relates to a sanitary single handle mixed flow unit / mixed flow valve (sanitary fittings), which has [0002] a) Accessory housing; [0003] b) a control cartridge arranged in the receiving chamber of the fitting housing and having at least one control member for controlling the flow of water, the control member being movable by means of an adjustment shaft pivotable about at least one axis; [0004] c) an annular cover, which covers a part of the accommodating chamber of the control cylinder upwards, and which has a protruding annular outer spherical crown viewed from above and is passed through by the adjustment shaft; [0005] d) Handle, which includes: [0006] da) a cover which overlaps the cover and has a receptacle on the underside of the cover into which the upper end region of the adjusting shaft can be inserted; [0007] db) a handle rigidly connected to the cover. Background technique [0008] Such hygienic single-ha...
