1. Designation:

Hydraulic and mechanical actuation of the outlet eccentric in connection with an outlet of an outlet valve.

2. Areas of application:

The invention relates to the possibility of temporarily closing a wash basin, sink, washbasin with an eccentric. This eccentric (valve cone) is guided by a pull rod that is guided in the sanitary fitting (e.g. two-handle fitting and single-lever mixer on a washbasin) and this serves to close the drain.

3. Technical problem:

The problem so far is caused by the often too small distance between the pull button and the existing wall. This distance is usually only 2 cm at most. This distance is far too small to operate this button and often causes difficulties.

4. Solution to the problem:

To eliminate this problem, this locking mechanism is incorporated into the outlet (5) of the fitting. This is operated as a rotary, sliding or cable pull mechanism.

6. Functional description:

By operating a sanitary fitting (e.g. WT, WFB etc.) using the handle (1) of the single-lever mixer, the inflow of cold water (2) and hot water (3) is opened, causing the mixed water to come out of the outlet (5). A rotary or pressure mechanism (6) made of plastic or ceramic is incorporated or screwed into the outlet side with the mixed water. The rotary knob (6) is provided with a longitudinal cut that is responsible for the cross-sectional narrowing. The narrowing of the outlet cross-section causes the channel for the line (4) to open, which can create a negative pressure. This negative pressure, caused by the cross-sectional narrowing (Venturi nozzle), causes a negative pressure to develop in the line (4). After the narrowest point of this nozzle, a line is incorporated through the housing to the outlet of the connecting lines. A plastic line is attached to this outlet to the inside of the overflow eccentric. This line is connected to the eccentric plug (8) on the underside with a diaphragm bellows (7). As the water flows out and the regulation or narrowing of the nozzle, an evacuation (negative pressure) is created in the line to the eccentric (valve cone). This negative pressure brings the eccentric back to its original position. The drain is thus closed. If no more water is fed into the sanitary object, the eccentric is held in its original position by the water level. If a second nozzle is opened using the rotary mechanism, the escaping water can be diverted. This water pressure from the water line fills the line (4) and the eccentric releases the outflow and the water can drain away unhindered. The line (4) is attached to the fitting with an O-ring, plug-in or clamp screw connection, as is the diaphragm bellows (7). The eccentric line is connected to the diaphragm bellows and is pushed through the screw connection on the drain nozzle, so that the eccentric can be connected to the line. The line is then connected to the fitting. To ensure that the drain is sealed to the line (4), an O-ring is pushed over this line and screwed tightly to the union nut on the drain nozzle.

7. Examples of implementation:

This process can be switched via a rotating or sliding mechanism.

Fig: 1 = Rotating mechanism:

The locking mechanism is activated by openings in the mechanism and the eccentric line that are offset to the side and by 90°.

Fig: 2 = Sliding mechanism:

The slider is moved horizontally, thereby regulating the two chamber openings that are located next to each other (Fig. 1).

Fig: 3 = Cable mechanism:

A cable pull (rotary knob) connected to this switch can also serve the function of opening and closing the eccentric. The cable pull is hooked into the control knob in the removed state via an integrated cable in the fitting. This is fitted with an O-ring so that no water can escape from the cable. The control knob is inserted into the outlet of the fitting and secured with the cable pull. The eccentric is then also connected.

8. Advantages: . ,·

- The narrowing also inevitably results in water savings!

- Handling the locking mechanism is thus made easier, as the space required by the current pull button of the rod mechanism and the rear wall is eliminated.

. - different processing techniques are possible

- easier adjustment options and smoother operation

Claims (1)

9. Right to protection: Hydraulic and mechanical actuation of a drain eccentric in connection in an outlet of a drain valve. This is characterized by the fact that a rotating, sliding or cable pull mechanism is incorporated into the outlet (5) of a sanitary fitting. This is subsequently screwed in tightly using threads and an O-ring on each side.
