DESCRIPTION OF PREFERRED EMBODIMENTS

In the FIG. 1 a perspective view of a drain fitting assembly 1 for a cistern is shown. The drain fitting assembly 1 is used for the controlled removal of rinse water from the cistern.

The waste fitting assembly 1 essentially comprises a valve body 2 with a sealing element 4, which cooperates with a valve seat 3, a valve housing 5, in which the valve body 2 is movably supported, and a holding unit 6 with a continuous discharge opening 7. The holding unit 6 serves the connection of the valve housing 5 with the cistern and through the drain opening 7, the rinse water flows from the cistern. The mounting unit protrudes into or through an opening in the cistern. The cistern is not shown in the figures.

The valve body 2 is movable with the sealing element 4 from the valve seat 3 along a central axis M from a rest position into a scavenging position and from the scavenging position into the rest position. For the movement corresponding control elements are present. The control elements bear the reference numeral 22. The control elements 22 may be designed in various ways. In the FIG. 1 is the valve body in the Spüllage in which water can drain through the drain opening 7.

Furthermore, the waste fitting arrangement 1 comprises a throttle element 10 which can be used if necessary for throttling the flushing water flow flowing out through the outflow opening 7. The throttle element 10 is in the FIGS. 2 to 4 shown in more detail.

The mounting unit 6 comprises a receptacle 9 for the throttle element 10, wherein the receptacle 9 is arranged in the installed position of the drain fitting assembly 1 below the valve seat 3. That is, the throttle element for throttling the effluent water flowing out through the drain opening 7 is insertable into the receptacle 9 and in turn removable from the receptacle 9.

The receptacle 9 is arranged in the embodiment shown in the interior of the drain opening 7. In particular, the receptacle 9 is arranged on the side wall 11 defining the outflow opening 7. The throttle element 10 is thus inserted into the drain opening 7 and throttles in the drain opening 7 the rinse water flow. The throttle element 10 is thus in communication with the mounting unit 6.

The receptacle 9 has here a cylindrical portion 25 and an end face 26. The cylindrical portion 25 is provided by the side wall 11 and the end face 26 is oriented substantially at right angles to the side wall 11-

Of the FIGS. 2 to 4 can be well recognized that the throttle element 10 extends from the side wall 11 of the receptacle 9, which faces the drain opening 7, in the cross section of the drain opening 7 hineinerstreckt. That is, the throttle element 10 thus extends from the outer side wall 11 in the direction of the center of the drain opening 7.

With regard to the radial extent, the throttle element 10 extends radially at most up to 20% of the diameter of the discharge opening 7 into the discharge opening 7. That is, the throttle element 10 does not extend into the center, but rather is arranged in the edge region of the drain opening 7. The throttling is thus effected by a change in cross section of the discharge opening 7 in the region of Throttling element 10, wherein the cross-sectional change is achieved by the throttle element 10 with respect to the cross section of the drain opening 7 from the outside. The inner cross section of the drain opening 7 remains untouched by the throttle element and there is also the flow of the flushing water flow is not disturbed.

In the embodiment shown, the throttle element 10 is formed in two parts. The throttle element 10 comprises a first throttle part 12 and a second throttle part 13.

The first throttle part 12 is firmly connected to the receptacle 9 in connection. Under a fixed connection is understood in this context, a rotationally fixed connection. That is, the first throttle part 12 can be inserted into the receptacle 9 and is firmly connected in the receptacle 9 with the receptacle 9. When not using the throttle element 10, the first throttle member 12 can be separated from the receptacle 9.

The second throttle part 13 is connectable to the first throttle part 12. The connection is such that the second throttle part 13 is adjustable with the first throttle part 12 along an adjustment movement. The adjusting movement is preferably a pivoting movement. The pivoting movement is indicated by the arrow V in the FIG. 3 shown.

In the FIG. 3 the first throttle part 12 is inserted in the receptacle 9 and the second throttle part 13 is in communication with the first throttle part 12. The second throttle part 13 is shown in its initial position. In the starting position, the second throttle part 13 has only a very small throttle effect. The throttle effect is provided here essentially by the first throttle part 12. That is, seen in the flow direction of the flushing water flow, which in the FIG. 3 is shown with the arrow F, essentially the first throttle part 12 provides a resistance to the flushing water flow.

In the FIG. 4 the second throttle part 13 is shown in the pivoted position to the first throttle part 12. In this case, the cross section in the throttle element 10 was further reduced. There are now both throttle parts 12, 13 counter to the flushing water flow and have a throttle effect.

In summary, with the throttle element 10 more throttle degrees can be achieved.

Of the Figures 2 and 3 can be well recognized that the two throttle parts 12, 13 are of identical construction. This has the advantage that the throttle element 10 can be easily mounted and there can be no confusion of one or the other part during assembly.

As a result, the specific design of the throttle parts 12, 13 will be described in more detail. In the illustrated embodiment, the throttle part 12, 13 comprises a ring section 14. The ring section 14 in this case has an outer diameter which corresponds essentially to the inner diameter of the receptacle 9.

From the ring portion 14 are each three throttle segments 15 in the direction of the center of the ring portion 14 from. The throttle segments 15 provide the actual resistance to the flushing water flow and throttle it. As explained above, the throttle segments 15 are not completely up to the center of the ring portion 15 from the ring portion 14, but extend to a maximum of 20% of the diameter of the drain opening 7 in the interior of the ring portion 14 a.

In the FIG. 3 It is shown that in the initial position, the throttle segments 15 of the second throttle part 12 are covered in the initial position substantially by the throttle segments 15 of the first throttle part 13. That is, in this illustrated embodiment, the throttle segments 15 of the first throttle part 13 provide the corresponding resistance. The throttle segments 15 of the second throttle part 12 can thereby be moved with the second throttle part 12 such that the degree of overlap decreases with increasing displacement. In this case, the throttle effect of the throttle element 10 increases overall. The maximum shift is in the FIG. 4 illustrated, in which case the throttle segments 15 of the first throttle member 12 and the throttle segments 15 of the second throttle member 13 preferably provide a drain opening 7 completely surrounding ring.

In the embodiment shown, three throttle segments 15 are arranged distributed at regular intervals per throttle part 12, 13 to each other. Between each of the three Throttle segments 15 is a gap 27. Preferably, the angular coverage of gap 27 and throttle segment 15 is equal.

The second throttle part 13 is attached to the first throttle part 12 via at least one latching tab 16. The latching tab 16 preferably acts on a throttle segment 15. In the embodiment shown per throttle segment 15 per a locking tab 16 is present. In this case, the locking tab 16 of the second throttle part 13 surrounds the throttle segment 15 of the first throttle part 12 accordingly.

In the embodiment shown, the second throttle part 13 is adjustable in deterministic increments to the first throttle part 12. For this purpose, the throttle segments 15 of the first throttle part 13 corresponding recesses 23, in which the latching tab 16 engages. There are two recesses per throttle segment available.

Next, the two throttle parts 12, 13 against each other acting stop elements 24. The stop elements 24 limit the relative movement between the two throttle parts 12, 13. In particular, the two stop elements 24 provide a stop in the starting position, so that the second throttle member 13 is displaceable relative to the first throttle member in one direction only, namely in the direction of the pivoting movement ,

Furthermore, the receptacle 9, as in the FIG. 2 can be seen, a latching structure 17. The latching structure 17 is arranged here in the region of the end face 26. With this latching structure 17, the throttle element 10 rotatably connected to the receptacle 9 can be connected. The latching structure 17 comprises in the embodiment shown a plurality of prongs 18. The prongs 18 are arranged uniformly distributed around the circumference of the discharge opening 7. In contrast, the throttle element 10 has a latching structure 19 which is suitable for the latching structure 17 of the receptacle. The latching structure 19 also has a plurality of prongs 28, which engage in the prongs 18 of the latching structure 17. In the embodiment shown, the prongs 28 are arranged in the region of the annular section 14 of the throttle part 12, 13. However, only the prongs 28 of the first throttle part 12 engage in the prongs 18 of the latching structure 17.

The mounting unit 6 also has lateral inlet openings 20. The inlet openings 20 are arranged in the installed position above the valve seat 3 and are arranged substantially below the bearing section 8, with which the valve housing 5 is connectable. Rinse water flows to the outlet opening 7 via the inlet openings 20.
