The invention relates to an emptying device for flushing tanks, the device comprising a housing comprising a float housing float hole retained by a support member above the float arranged in a concentric piercing tube of the housing, float housing and float, the tube having an opening at its lower end in addition, the device comprises a second valve arranged concentrically with respect to the first valve, which is controlled by a second float so that when the rinsing tank is partially emptied of water it closes the flow of the rest of the water.

Such a flushing tank emptying device is known, for example, from DE publication 1 905 978. It makes it possible to empty either the entire contents of the flushing tank or only a certain part of its contents.

The construction of this known emptying device, in which the two floats are arranged concentrically one on top of the other, has the disadvantage that the construction height of the rinsing tank becomes relatively high.

2 62165

The object of the invention is to provide a flushing tank emptying device for two different amounts of flushing water, which device can be used in connection with a relatively low and wide flushing tank while maintaining a uniform structure in one housing with one flushing opening.

To achieve this purpose, the flushing tank emptying device according to the invention is characterized in that the lower, expanded diameter end of the tube has an inwardly directed flange forming a valve seat on the valve plate of the second valve arranged in this tube at the lower end of the inner tube movably mounted, and a stop is provided on the jacket surface, e.g.

This structural implementation makes it possible to place the second float on the side approximately next to the first float, as a result of which the required low construction height of the flushing tank can be achieved.

In the following, an embodiment of the invention will be illustrated with reference to the accompanying drawing, which shows the rinsing tank emptying device according to the invention in longitudinal section.

The emptying device has a cylindrical housing 1 which, by means of a lower inwardly directed flange 2, becomes a threaded nozzle 3. The nozzle 3 grips in a known manner through the bottom of a rinsing tank (not shown) and is also connected to a discharge line (not shown). The housing 1 has openings 9 immediately above the flange 2 through which the water in the rinsing tank can flow through. The housing 1 has a float housing 22 contained in an annular float 21, the bottom 23 of which has holes 6. The float housing 22 also has an inner jacket 25 which is slightly shorter than the outer jacket. The inner jacket 25 acts as a guide for the axially displaceable tube 12, which is widened at its lower end and supports a rubber or plastic valve plate 13 which acts as a closure between the two rings 14 and 15. The plate 13 is on the shoulder-like valve seat 16 in the closed valve position.

The tubes 12 support a support ring 12b at their top, which acts as a support for the float 21.

The tube 12 passed through the inner wall of the float housing 22 has openings 12a. The tube 12 surrounds a second tube 17a which supports at its lower end a second valve plate 20a which cooperates with a valve seat 24a belonging to a ring 15 of the tube 12. At the top, the tube 17a supports a projecting shoulder 17b. In the upper part of the housing 1, a two-lever lever 33, 33a is pivotally mounted on the shaft 34. The lever arm 33 supports the float 35. The lever arm 33a runs parallel to the tube 17a when the rinsing tank is not filled. However, if the rinsing tank is filled with water, then the lower float 21 rests on the abutment ring 12b of the tube 12 and the upper float 35 presses the lever arm 33a against the tube 17a.

Now that the tube 17a is raised by the actuator (not shown) to such an extent that the lever arm can engage under the shoulder 17b, some of the water flows out of the rinsing tank until the float 35 has lowered so far that the lever arm 33a releases the tube 17a. As a result, the valve plate 20a presses again on the seat 24a.

However, if the pipe 17a is raised so high that the retention of the valve plate 20a can also move the pipe 12 upwards, then the valve plate 13 opens, allowing the entire contents of the flushing tank to flow out.

Claims (1)

An emptying device for a flushing tank, the device comprising a housing (1) comprising a float housing (22) with floats (21) held by a support member (12b) above the float arranged in the housing (1), the float housing (22) and the float (21) to a concentrically piercing tube (12), the tube (12) being provided at its lower end with a valve plate (13) for opening which the tube (12) can be pulled upwards, the device further comprising a second, concentrically relative to the first valve plate (13) a valve plate (20a) arranged by a second float (35) so as to partially shut off the flow of the rest of the water when the flushing tank is partially emptied of water, characterized in that the lower, expanded diameter end of the pipe (12) has an inwardly directed flange forming a valve a seat (24a) for the valve plate (20a) of the second valve, which is arranged in this tube (12) by an inner tube (17a) movably mounted ) at the lower end, and that a stop (17b), e.g. a ball, is arranged on the upper jacket surface of the inner tube (17a), whereby the angle lever (33, 33a) cooperating with the second float (35) engages under the stop (17b) when the inner tube (17a) is lifted and retains the inner tube (17a) in the raised position until a corresponding amount of water has flowed out of the flushing tank (7) through the second valve (20a, 24a) opened.
