Fig. 4 is a schematic representation of the distributor all, in the rest position.

Fig. 1 shows a VC bowl T, the shape of which widens upwards and which has a water-odor trap at the bottom. It has a flushing ramp that goes through accordingly inclined alignment of openings the coating of the entire j th surface of the bowl from top to bottom.

In the working cycle, the flushing ramp is first influenced, namely before the closure member 3 opens, which is normally the case is held on its seat 4.

A device has already been described in French patent application 72 36 978. In this device, first a cleaning of the bowl on its entire usable area, made, d. H. unwinding any material or scrap of paper on the non-submerged part of the bowl may have established. After a certain time - such as a few seconds - the closure member 3 opens so suddenly as possible, and after the substances practically instantly-. borrowed were carried away, a device brings das.Verschleußorgan 3 automatically back into its starting position (closed position) return. In the device according to the above-mentioned patent application, only the water odor trap was on the bottom the bowl 1 is not provided.

The device according to the invention consists essentially of the following elements, namely a tap, a slider D serving for operation, a memory R (reservoir en charge for the delay and a piston-cylinder unit V.

These elements are connected to one another by pipelines. The slide D consists of a rod 6 on which three pistons

7, 8 and 9 are attached. and which can be actuated by a button 14. The pistons 7 and 6 have the same diameter, while the diameter of the piston 9 is larger. The pistons 7 to 9 move in a corresponding cylindrical body L Various lines open into the cylinder body of the slide D.

An opening 10 corresponds to the one coming from the main supply Water supply to the device. An opening 11 corresponds to the line that connects the slide 2 to the rear of the piston-cylinder unit V connects and has an opening 15 with the rear side 16 of the piston 17 connection. An opening 12 corresponds to the flow to the memory R. An opening 13 corresponds to the inlet to the memory R, more precisely, to the automatic one Delay device 21.

As can be seen from FIG. 4, the rod 6 can assume a position in which the water flowing in via the opening 10 has only one possible outlet, namely Via the opening 11, that is, it enters the piston-cylinder unit at 15 and on the rear side 16 of a piston 17 Exerting pressure. This piston 17 is firmly connected via a rod 18 to the closure member 3, which rests on its seat, to ensure the seal and hold back the odor trap water to prevent odors from entering the Toilet scabbard 1 to prevent.

Fig. 1 shows the state after pressing the button 14, whereby the rod 6 and the pistons 7, 8 and 9 moved down became.

In this case, the water flowing in via the opening 10 passes over the opening 13 and the line 19 in the upper part of the memory R, which has no cover, so that it is ventilated.

The line 19 opens into a chamber 21 (FIGS. 1 and 3), and although in the case shown there are two Dro.sselbohi ^ ungjan 201 und_ j

202, opposite which a shoulder 28 is provided, which forms a seat for a ball 26 and has two bores, .die to lines 29 and 30, which lead to the flushing ramp and into the memory R, respectively.

In the upper part of the chamber 21 a line 22 is provided which to the front 23 of the piston 17 of the piston-cylinder unit V leads.

In the lower part of the chamber 21 is a hollow vertical extension 50 with two superposed seats 25 and 25 for each one of the two balls 26 and 27, the density of which is smaller than 1 is provided.

The lower seat 25 is tight, while the upper seat 24 is permeable is, d. H. the passage of water is allowed in both directions. The upper seat 24 prevents upward movement the ball 27, while the seat 25 prevents the ball 27 from moving downward and passing through the bore 51.

The ball 26, on the other hand, can rise into the interior of the chamber 21 and in particular come to rest on the shoulder 28, which is caused by a conical part lying in front of the shoulder 28 27 is supported, which leads to the seat located in front of the lines 29 and 30.

To avoid any possibility of pushing water back into the central chamber 21 by additional means in the lines To avoid mounted organs, it is expedient to have a single line 30 under the shoulder 28 and the corresponding seat provide, which is returned to the spoke R after feeding the flushing ramp and in this way to the place of Line 29 occurs. In this case there is only one orifice hole 201 is required, which feeds a jet to the bore corresponding to the line 30. The throttle bores 201 and 202 have a smaller diameter than the lines 29 and

30, so that the emerging from the throttle bores 201 and 202 The jet enters the conduits 29 and 30 directly if it is not prevented from doing so by the ball 26.

-The inlet opening of the line 22 has a smaller diameter than the ball 26 so that it cannot enter the line.

The slide D is also connected to the floor via a line 32 of the memory R connected via an opening 33. The;

Line 32 opens into the cylinder of the safety valve D via an off ^! opening 31 which is arranged so that it is closed by the piston 8 when the button 14 is depressed (Fig. 1).

In the rest position of the slide D, when the button 14 is

ben is (Fig. 4), however, the openings 13, 31 and 34 are together in connection, since they flow into a common chamber, ' which is delimited by the piston 8 and 9. Since the opening 34 j corresponds to the line 35, which connects the slide D with the bottom of the bowl 1 (opening 36), in this way a Outlet of the storage tank & created in the bowl 1.

Furthermore, a device is provided that the automatic return of the row-cylinder unit V in its closed position causes. This device is described below.

It consists of two bores 37 and 38 which are provided in the rod 18 connecting the piston 17 to the closure member 3 and are connected to one another by a channel 39. In a known manner, the rod 18 passes through a bore made by two bead rings 52 and 53 is sealed, between which an annular groove 40 is provided. In this groove 40 can de Bore 37 open when the piston-cylinder unit is in the position in which the closure member 3 is completely open is.

One provided in the wall of the device opens into the groove 40 Bore 41 which opens via a bore 42. ^ This bore 42 is connected to a line 43 which the Groove 40 connects to the lower part of the slide D below the piston 9, through an opening 44 with a Chamber 45 (Fig. 4).

The arrangement of the pistons 7, 8 and 9 and the openings 10, 11, 12, 13, 31, 34 and 44 to each other in the distributor is as follows chosen:

When the rod B is completely raised (rest position, FIG. 4), the piston 7 closes the opening 12 and the openings 10 and 11 open into a chamber, which of the pistons 7 and

6 is formed; the openings 13, 31 and 34 open into one Chamber formed by pistons B and 9, the opening 44 opens into the chamber 45 which is formed below the raised piston 9.

When the rod 6 is completely pushed down by the button 14 (working position - Fig. 1), the openings open 11 and 12 in an existing above the piston 7 combs Openings 10, 10 and 13 open into the chamber between the piston

7 and 8j the opening 31 is closed by the piston 8; the opening 34 opens into a chamber located between the piston 8 and 9 and the opening 44 opens directly below the piston 9 in the lower position.

To allow the downward movement of the piston 9 is in this seen a bore 54 with a relatively small diameter before.

This device works as follows: In the rest position (Fig. 4), the sealing of the closure member 3 is on the ground the bowl 1 by the pressure of the flowing through the opening 10 Guaranteed supply water that is in the between

the piston 7 and 8 located chamber of the distributor enters, leaves this chamber via the opening 11 and into the line 48 j which opens into the piston-cylinder unit V via the opening 15, and against the rear side 16 of the piston 17 presses, whose pressure force from the rod 18 on the closure member 3 is transmitted.

The force exerted is relatively high and the seal will do so effectively ensures that water is retained at the bottom of the bowl 1, the rise of odors with certainty prevented.

If the substances are to be emptied after the bowl 11 has been used, the button 14 is pressed so that the rod B and the pistons 7, 8 and 9 are brought into the position of Fig.1. In this position, it occurs through the opening 10 water flowing into the opening between the pistons 7 and 6 13 and the line 19 and passes through the throttle bores 201 and 202 into the chamber 21 in the form of jets, which enters the lines 29 and 30 and the supply of the flushing ramp 2 and the cleaning of the bowl 1 as well ensure that the memory R is filled.

If only a single thrush beating 201 and a single one Line 30 is provided, can - as already said, the water that feeds the Bespülungsrarnpe 2, the memory Fill in R.

While the reservoir R is being filled, the water rises and, when it reaches the bore 51, the ball rises. 27, their Density is less than 1, and reaches the seat 24. If the water now rises further, it lifts the ball 26, which, if it in the height, the chamber 21 reaches, from the one or the through the Throttle bores 201 and 202 generated beams is sucked and is thrown to the seat 28. The ball 26 closes now the water supply via lines 29 and 30.

The water now fills the chamber 21 and presses the ball 27 against the seat 25. When the chamber 21 is completely filled, the water exits via the line 22 and reaches the rear side 23 of the piston 17 of the piston-cylinder unit V and veiischiebi this, with its movement on the rod 18 and the encryption \ circuit member 3 is transmitted. This movement is very fast and can therefore happen because the water located in the piston-cylinder unit V on the rear side 16 of the piston 17 can escape via the opening 15 and the line 48 and via the opening 11 into the above Piston 7 located chamber of the slide D can enter in order to be in the upper part of the memory R via the opening 12 and a line 49.

The filling of the memory R and the simultaneous taking place Rinsing of the bowl 1 is stopped as soon as the water supply in the memory R is established. This water supply, one has a predetermined volume, forms the odor trap water retained at the bottom of the bowl after the end of the working cycle.

Within the scope of the invention, this automatic delay device of the memory can also be designed differently. For example, instead of the ball 27, a closure with a Spring can be used. It is simply a matter of using a simple valve that is in a device made up of elements 201, 202, 21, 22, 24 and 26 after filling the memory R branches off a stream of water for another purpose.

After filling the memory R, the whole is over the opening 10 inflowing water flow through the opening 13, the line 19, the chamber 21, the line 22 of the front side 23, the piston 17 of the piston-cylinder unit V and presses it Piston 17 backwards so that the closure member 3 is opened.

When the closure member 3 is completely open, the water located on the front side 23 of the piston 17 passes over the Bohrun.g 38, the channel 39 and the bore 37 in the annular Groove 40, into the bore 41, the bore 42 and finally into the line 43 and is via the opening 44 into the chamber 45 inserted under the piston 9 (control piston) of the slide D. A throttle 46 is provided for regulating the speed of movement of the piston 9. The slide D is thereby brought into the position according to FIG. 4, so that the water flowing in at 10 in that formed by the pistons 7 and 8 Chamber enters and via the opening 11, the line 48 and the opening 15 in the piston-cylinder unit V enters and acts on the rear side 16 of the piston 17, which is thereby pressed forward and the closure member 3 close to his Seat 4 is pressing.

In the meantime, this is done on the front side 23 of the piston 17 located water is pressed via the line 22 into the chamber 21, from which it is only via the throttle bores 201 and 202, the line 19 and the opening 13 in the cylinder cjes slide] D can emerge from which it via the opening 31 and the line device 32 to the bottom of the memory or via the opening 34 and the line 35 to the bottom of the bowl 1. If the closure member 3 is tightly closed, the water stops flowing into the skein D and acts in the piston-cylinder unit V static. As a result, the external pressure of the The water supply network is no longer in the district 10, 11, 48, 15, 15. The water in the storage tank R is now emptied directly over the opening 33, the conduit 32, the opening 31, the opening 34, the conduit 35 and the opening 36 in the bowl 1.

In order for this operation to take place, the opening must 31 lower than the opening 33 and the opening 36 lower than the opening 34, as es.in the drawing is shown.

The water in the chamber 21 also flows out, because the pressure in this chamber is practically zero, since they have the throttle bores 201, 202, the line 19, the _t opening 13, the opening 34, the opening 35 and the opening 36 is connected to a drain to the bowl 1. As a result, the ball 27 lifts off and floats on the water and allows the water to be emptied from the shoulder 28. The ball 26, which was blocked at this shoulder, now moves downwards and falls onto its seat 24 and the reservoir R empties completely in order to form the odor trap water at the bottom of the bowl 1. The device is now ready for triggering a new work cycle by acting on button 14.

At the start of operation, i. H. during the entire time the filling, the pressure in the piston-cylinder unit V is both on one side of the piston 17 and on the other side zero.

In order to avoid the weight of the water on the ground

which is the Schüssel.1 and exerts a slight pressure on the closure member, this opens only a little too early, the rubber covering of the seat 4,. which causes the seal, have a concave shape so that it forms a suction cup.

Various modifications are also within the scope of the invention and changes in details of the facilities described possible. For example, the system for blocking the water flush as well as the liquid metering device can also be used for other purposes. Likewise, the control of a closure member 3 by a hydraulic Piston-cylinder unit can be used for other purposes.

The device according to the invention has the following advantages: j Very little water consumption _{(because sjißjjei _jjBdem_Ar ^ __}
