Single lever sanitary mixer tap

The invention relates to a sanitary single-lever mixer tap, consisting of a valve body with a fixed disc, which has inlet passages, which on the a disc surface connected to the hot and cold water pipe and on the other surface of the disc against a slide by a control lever on the fixed disc and rotatable, with a surface channel for mixing and deflecting functions provided disc, which with the inlet passages and at least one also in the fixed disc located and connected to the outlet outlet passage more or less in Cover can be brought.

There is a disadvantage with mixer taps of this type, which has been tried and tested per se it can be seen that the operating cross-section of the outlet passage is equal to or larger than the operating cross-sections the inlet passages together. It has been shown in practice that such cross-sectional dimensions annoying noises can occur.

The invention is based on the object of eliminating this disadvantage and creating a sanitary single-lever mixer tap, which in spite of a simple design a reliable

guaranteed. , 2230174

This goal has essentially been achieved in an advantageous manner in that the operating cross-sections of the inlet passages together in each operating condition are at least as large as the operating cross-section of the outlet passage.

According to a design feature of the invention, the sealing surface of the displaceable and rotatable disk completely or partially the surface channel in the area of the outlet passage, and it serves in this area as the operating area of the outlet passage depending on the particular one Operating cross-section of the inlet passages changing storage area.

According to a further design feature of the invention, the storage area can consist of a completely bridging channel over the surface Be formed web.

The flow rate in the inlet passages is reduced by the back pressure achieved with the storage area, whereby the mixer tap makes a lower noise level.

The mixer tap can also be used as a distribution valve for low-pressure accumulators can be used.

In the drawing, the subject matter of the invention is in one embodiment shown, namely show:

Fig. 1 a slidable and rotatable disc in the front view,

Fig. 2 shows a longitudinal section along the line A-A of Fig. 1 and

/ 3 ... 309883/0094

Fig. 3 shows a fixed disc in the front view with the sliding and rotatable disc in dashed lines. ...

The fixed disk is designated by 4 therein. It has two inlet passages 5 and 6, on the one hand with the hot or cold water line are in connection and on the other hand against a by a control lever on the fixed Disc 4 slidable and rotatable, with a surface channel 7 provided for mixing and deflection functions disc 8 are directed. The surface channel 7 can with the Inlet passages 5 and 6 and at least one also located in the fixed disc 4 and with one Outlet connected outlet passage 9 are more or less brought into overlap.

As can be seen, the sealing surface 10 of the disk 8 partially covers the surface channel 7 in the area of the outlet passage 9. It serves in this area as a storage area, which the operating cross-section of the outlet passage 9 as a function of the respective operating cross-section of the inlet passages 5 and 6 changed. The storage area is through a Surface channel 7 entirely bridging web 11 is formed.

The battery is also available as a distribution or mixing valve for low-pressure accumulators suitable. For this purpose, the passage 9 serves as an inlet for the cold water and z. B. the passage 5 as a direct connection to the outlet, while cold water flows into the low-pressure accumulator via passage 6 can. In the closed state, the storage area closes the passage 9. The area then exposed to the water pressure is so small that it is impossible to take off.

As already mentioned, the one shown and described is
Execution is only one example for the implementation of the invention, and this is not limited to it; rather, other possibilities are also given within the scope of the basic idea according to the invention, in particular with regard to the special design of the disc 8.
