Float vessel necessary if you want the valve to turn closes a predetermined time. This disadvantage has been remedied in the case of the drain fitting after the innovation by the fact that the float vessel is also provided with an inner jacket, the .the pipe with a lot of play, and that contained in the float vessel Water can only run off through one or more openings provided in its bottom. .

An exemplary embodiment is shown in section in the drawing shown. .

The waste set shown has a cylindrical Housing 1 on the bottom via an inwardly directed flange 2 merges into a connecting piece 3 which is provided with an external thread 4 is. The bottom 5 of a toilet cistern of the usual type, otherwise not shown, has an opening 6 through which the nozzle 3 is inserted through. With one on the thread 4 seated nut 7, the housing 1 is attached to the floor 4, a seal 8 lying under the flange 2 for sealing serves. A drain line, not shown, leading to the toilet bowl is also connected to the nozzle 3.

The housing 1 is immediately above the flange 2 with four large Fe.nstern 9 provided, through which thus the in the cistern existing water can pass through »The housing is at the top with a cover hood 10 which has a central bore 11 through which a tube 12 passes in the usual manner, the one at the bottom with a valve plate made of strong rubber, for example 13 is provided ', the latter being fastened between two on the pipe 12-

th, e.g. glued on rings 14 and 15. Of the Valve disk 13 cooperates with a valve seat which is formed by a small bead 16 on the inner edge of the upper surface of the flange 2 is provided.

The tube 12 is connected at the top with a connection pipe 17, are provided at the upper end, two mutually opposite, radial bores 18, engages in ¹ which an unillustrated fork piece, which is connected in a conventional manner with the operating handle, which for opening of the drain valve 13 , 16 is used by pulling the tube 12 upwards. Two windows 19 provided slightly below the bores 18 in the connecting pipe 17 form an overflow for the water contained in the cistern, in the event that the float-operated valve attached to the same as usual does not stop the water from flowing into the cistern before its mirror the , Overflow edge 20 reached.

In the housing 1 there is a float 21 containing, cylindrical float vessel 22, the bottom 23 of which is on a shoulder 24 of the housing is supported and its outer jacket 24 * directly along the inner wall of the housing 1 to Cover hood 10 extends from which the float vessel.22 thus is held on the shoulder 24. In contrast to float tanks In known drain fittings, the float vessel 22 also has an inner jacket 25 which is only slightly shorter than that Outer jacket 22 between the tube 12 and the inner jacket 24 is a very significant game 26 available, with the leadership of the

Pipe. 12 only some of the inner jacket 24 protruding inward, small projections 27 are provided. On the floor 23 are some, 2.B. three, radial ribs 28 are provided on which the float 21 rests when there is no water in the float vessel 22. in the At the bottom 23 there are two bores 29, for example about 4 mm in diameter. In the drawing, only one rib 2Θ and one hole 29 are visible. A ring 30 is attached to the tube 12, of which some arms 31 protrude downwards, at the lower ends of which a support ring 32 is attached. ',

The waste set described is in the drawing in shown the position that it assumes when the cistern is empty. When water runs into the same, it fills the housing 1 and the float vessel 22 by passing it through the window 9, the game 26 between tube 12 and inner jacket 25 and the game of the pipe 12 in the bore 11 flows. Swimmer 21 is coming thereby into the position 21 · indicated by dash-dotted lines, in which he supports itself on ring 32 but cannot lift the pipe because the latter by the pressure of the water on the valve disc 13 in in its illustrated position, i.e. the valve 13, 16 remains closed.

When the drain valve 13, 16 is opened by pulling the pipe 12 upwards, the float 21 rises to the dot-dash line indicated position 21 ", in which it is located at the bottom of the Cover hood 10 is supported, while the tube 12 over the in the position 32 "is supported on the float. The water in the cistern now runs through the open valve

13, "16 and the connection piece 3. If the holes 29 are not available the float vessel 22 would now remain filled up to the upper end of its inner jacket 25, so that the float 21 in its position 21 ″ would keep the valve 13, 16 open

but empties the float vessel 22 through the two holes 29, located · '·

lower / float 21 and tube 12 slowly so that after the Emptying the cistern takes about 7-8 seconds, for example the valve 13, 16 returns to its closed position and the cistern ^ fills up again, because that is in the same attached, float-operated valve when lowering the water level opens automatically.

The diameter of the drainage holes 29 of the float vessel On the basis of tests, 22 can very easily be dimensioned in such a way that that the drain valve 13, 16 remains open as long as this it is asked for. Two drain holes are provided so that the same Drain fitting also used for flushing urinals Cisterns can be used where it is desired that the ' To keep drain valve .13, 16 offBn for a longer period of time in order to

- through

Refill the empty siphon / refilling water in the rinsing process. It is then sufficient to close one of the bores 29 with a pin conclude; around the opening time dBs valve to about 15 seconds raise. With the previous drain fittings, with a float vessel Without an inner jacket, the rate of emptying of the float vessel depended on it from the width of a narrow gap between the edge of a central opening of the bottom of the vessel and the tube 12 was present. As a result, it was only minor

Tolerances in the pipe outside diameter and in the diameter of the named Opening were permissible, which made production considerably more expensive. The present construction allows large tolerances the main parts of the set consisting of plastic, but with the desired opening time of the Drain valve can be adhered to very precisely. If you are in Bottom 23 an opening of adjustable free flow cross-section provides, you can even achieve a continuously adjustable opening time over a wide range.

Another important advantage of the waste set described lies in the fact that the valve seat 16 is provided on the housing 1 ″, and not, as before, on the edge of the base 5 of the Opening provided for play box 6. If the valve, seat 16, it is sufficient to replace the housing 1 of the waste set, while previously the entire cistern was replaced had to become.

It is clear that the connecting pipe 17 is by no means necessary. .This pipe 17 is only provided to the set by replacing or omitting the same - the latter with drilling holes 18 or the like. At the upper end of the tube 12 - easy to adapt to different cisterns.
