Description

The invention relates to a set with a filling valve for mounting in a cistern according to the preamble of claim 1. The invention further relates to a cistern in which a filling valve of a set according to the invention is fixed.

A generic set comprises a filling valve which is designed to control the water supply into a cistern. For this purpose, the filling valve has an inlet side, which is designed to connect a water pipe. For this purpose, the filling valve has a pipe socket on its input side, which extends with its axis in an axial direction. It is self-evident to the person skilled in the art that the pipe socket is designed in the manner of a pipe, which has a clear cross section and is designed for guiding water within its cross section, the axis assigned to the pipe or the pipe socket extending perpendicular to the clear cross section. The suitability of the input side for connecting a water pipe can be realized, for example, via an external thread provided on the pipe socket or an internal thread provided in the pipe socket, onto or into which a corresponding nut can be screwed, which is connected in a conventional manner to a water pipe. Alternatively, said suitability can be provided, for example, by the fact that the Pipe socket has a flange and a union nut held by the flange is arranged on the pipe socket and can be screwed onto a connecting piece which is connected in a conventional manner to a water pipe. The filling valve of a generic set also has an outlet side, which is designed to discharge water into the cistern. The filling valve is thus designed to be connected to a water pipe on the inlet side and to deliver water to the cistern on the outlet side. Such a filling valve preferably has a valve element which is arranged between the input side and the output side and via which the provision of the fluid-carrying connection between the input side and the output side can be controlled. In a first operating position, the valve element provides a fluid-carrying connection between the input side and the output side, so that water can flow from the input side to the output side, in a second position the valve element prevents a fluid-carrying connection between the input side and the output side. Usually, the valve element is preferably controlled via a float, which is coupled to the valve element. According to the intended purpose, the filling valve is mounted in a cistern in such a way that the float assumes a certain vertical position depending on the water level in the cistern, the float being coupled to the valve element in such a way that it controls the valve element in a certain vertical position range Provide fluid-carrying connection between the input side and output side, and in another specific vertical position range controls the valve element to prevent a fluid-carrying connection between the input side and output side.

The filling valve of a generic set is thus in one Cistern, ie in the interior of a cistern, in which the cistern stores water, to be installed and connected with its input side to a water pipe, the fill valve controlling the inflow of water into the cistern depending on the water level in the cistern. Such filling valves have long been known standard products in the sanitary sector. When used as intended in a cistern, they are exposed to high loads, since they change their operating position with every relevant change in the water level in the cistern, in particular each time a flushing system supplied by the cistern is operated, namely alternately providing a fluid-carrying connection between the inlet and outlet sides and prevent what happens many times a day in a typical filling valve environment. In addition, such filling valves are exposed to limescale. For this reason, malfunctions usually occur with such filling valves after some time, which is why such filling valves often have to be replaced. Such an exchange is often problematic for an installer. This is because there is a very large number of different variants of cisterns from different manufacturers on the market, and depending on the cistern variant, there are different assembly devices in the cistern, to which filling valves corresponding to the assembly devices are attached. Not only do the assembly devices from different manufacturers differ, but even with different cistern variants from one manufacturer there are very different versions of assembly devices. The manufacturers of cisterns offer filling valves which are specifically adapted to the respective assembly device they offer and which can then be mounted on the respective assembly device which is provided in the respective cistern variant. It is therefore to replace a filling valve in a cistern Requires that the mounting device provided in the cistern is first identified and then a filling valve corresponding to the mounting device is procured so that this filling valve can then be installed in the cistern via the mounting device which is provided in the interior of the cistern and is attached to the wall of the cistern . Such an approach is not only time consuming but also costly. On the one hand, an installer usually has to appear at a customer several times before he can replace a filling valve, on the other hand, an installer has to order a large number of different filling valves in small quantities and / or keep them in stock.

From the document FR 2663970 A1 it is known, for example, to fix a filling valve to a cistern via a mounting adapter which is connected to a pipe socket of the filling valve and which has a cylinder section with an external thread on which two nuts are screwed, the cylinder section being inserted through an opening in a cistern wall and the two nuts are screwed from both sides against the cistern wall. From the document DE 201 03 210 U1 it is known, for example, to connect a filling valve to a supply line via a connecting piece, the connecting piece being passed through an opening provided in a cistern wall, a receptacle with a thickening being arranged in the opening and the connecting piece having a groove corresponding to the thickening , so that the connection piece is held in the opening by the interaction of groove and thickening. From the document WO 2008/051311 A1 For example, a filling valve is known which has a short nozzle and which can be connected to a hose via an adapter, the Adapter is held on the filling valve via a holding mechanism.

The present invention has for its object to provide a set comprising a filling valve for mounting in a cistern, which at least partially eliminates at least some of the disadvantages and problems described above.

As a solution to the described problem underlying the invention, the invention proposes a set according to the features of claim 1. The set according to the invention comprises a filling valve for mounting in a cistern, which has an inlet side for connecting a water pipe and an outlet side for dispensing water into the cistern. The filling valve has on its input side a pipe socket extending with its axis in the axial direction. The set according to the invention can in particular have further features described in connection with generic sets. The set according to the invention also has a mounting adapter with an axially, ie along the axial direction, connecting section and a nut corresponding to the pipe socket. The nut and pipe socket are in relation to each other as explained for the generic sets trained accordingly. For example, the nut can have an internal thread and the pipe socket can have an external thread. For example, the nut can have an external thread and the pipe socket can have an internal thread. In the two cases mentioned, the respective threads correspond to one another in such a way that the nut can be screwed onto the pipe socket. For example, the nut can also be designed as a union nut provided on the pipe socket, which can be screwed onto a corresponding thread of a connection piece, such as, for example, a connection piece of a water pipe or a connection piece of the connecting section. The nut, the mounting adapter and the pipe socket are designed to correspond to one another in such a way that the mounting adapter can be sealingly fixed with its connecting section against the pipe socket in an installation position of the set. For example, for this purpose the nut can be designed as a union nut arranged on the pipe socket, which is screwed onto a thread provided on the connecting section and in the assembly position presses the connecting section axially against an axial end face of the pipe socket. For example, for this purpose the nut can have an internal thread and the pipe socket has a corresponding external thread, the nut starting from its internal thread having a radially inward projection and the connecting section being arranged in the assembly position within the internal thread of the nut and axially over the projection of the nut is pressed against an axial end face of the pipe socket. For example, the connecting section can comprise a cylindrical axial section, which is arranged in the assembly position within the pipe socket and is sealed in particular via a sealing ring, for example an O-ring, to the pipe socket, the cylindrical axial section via the nut, which is in the assembly position in or on the Pipe socket is screwed, is held in the pipe socket. The mounting adapter also has a cylinder section which has an external thread on its outside and which, in the mounting position, extends axially away from the pipe socket, starting from the connecting section. The cylinder section is thus axially offset from the connecting section. In the assembly position, its external thread is freely accessible, since it extends axially away from the pipe socket, starting from the connecting section, and is located axially next to the pipe socket. The mounting adapter also has a holding section that extends radially outside the cylinder section. In general, each radial direction is perpendicular to the axial direction. In one embodiment, the holding section is delimited in a first radial direction by two opposite transverse ends running radially outside the cylinder section. Each of the transverse ends extends along a second radial direction, which is perpendicular to the first radial direction, on at least one radial end of the cylinder section beyond the cylinder section, in particular over at least one third of the diameter of the cylinder section beyond the cylinder section and / or over at least 5 mm beyond the cylinder section. The radial end preferably refers to the second radial direction. In particular, each transverse end extends at this radial end over a first extent along the second radial direction beyond the cylinder section and extends at the radial end with respect to the first radial Direction beyond a second extension region beyond the cylinder section, the length of the first extension region along the second radial direction being at least 1.5 times, in particular at least twice, in particular at least 3 times the length of the second radial extension region along the first radial direction. In a further embodiment, which can be combined in particular with the aforementioned, the holding section has latching lugs on its end face which points axially away from the pipe socket outside the radial extent of the cylinder section.

The set according to the invention thus has a mounting adapter which can be fixed via the nut to the pipe socket of the filling valve and which, thanks to its design according to the invention, guarantees a multitude of different mounting options in a cistern. Using the set according to the invention, the filling valve can thus be mounted on a large number of known mounting devices via the mounting adapter. The set according to the invention thus has the particular advantage that it enables the filling valve included in the set to be installed in almost all common cisterns, so that an installer who is called to a customer to replace a valve is very likely to the set according to the invention can immediately replace the filling valve on site. This saves time, replacement costs and costs for the manufacture and supply of the filling valve required for the replacement. The set according to the invention obtains particular flexibility via the mounting adapter, which on the one hand has a cylinder section with an external thread which projects axially from the pipe socket, and on the other hand a holding section which has the explained transverse ends and / or the explained latching lugs. The mounting adapter is, for example, on a U-shaped one via the cylinder section Mounting device mountable by screwing onto the cylinder section at least one fixing nut that presses against the U-shaped mounting device. The mounting adapter can be attached to other common mounting devices via the holding section. For example, assembly devices with a rail guide are known, into which the assembly adapter in one embodiment according to the invention can be inserted with one or both of its transverse ends extending radially outside the cylinder section. For this it is essential that the transverse ends run radially outside the cylinder section so that they can be fixed radially outside the cylinder section to an assembly device and the cylinder section is still accessible. In general, the cylinder section is particularly preferably connected in a fluid-carrying manner to the connecting section, which in turn is connected in a fluid-carrying manner to the pipe socket in the assembly position. This can make it possible, for example, to connect a water line to an end face of the cylinder section. The provision of corresponding transverse ends is also particularly advantageous for this, since a water pipe can then be connected to the cylinder section and, at the same time, the mounting adapter can be fixed radially outside the cylinder section and thus next to the water pipe. The transverse ends run particularly preferably, ie the holding section runs in a straight line along the sides delimited by the transverse ends, along the second radial direction, for example straight over its averaged course, for example continuously throughout. As a result, insertion and fixation in a corresponding rail guide of an assembly device can be particularly favored. The two transverse ends particularly preferably run parallel, so that the holding section has two transverse sides running parallel at least in sections. This can be particularly advantageous for the insertion and fixing of the mounting adapter in a rail guide leading on both sides. The provision of latching lugs on the holding section, which are arranged outside the radial extension of the cylinder section, described for an embodiment according to the invention has the particular advantage that the mounting adapter can be inserted through a recess into a mounting device and latched with its latching lugs in the recess can be. Since the locking lugs extend outside the radial extent of the cylinder section, the cylinder section is also accessible in such a position of the mounting adapter that is fixed to a mounting device, so that a water line can also be connected to an axial end face of the cylinder section in this position.

In general, the present invention is based on the finding that a universally usable set for mounting a filling valve in a cistern can be provided in a very simple manner by providing a mounting adapter that can be mounted on the pipe socket on the inlet side of the filling valve and that has different sections, each of which enables completely different mounting options on mounting devices which are widely used in conventional cisterns. By providing the mounting adapter on the inlet side of the filling valve, a particularly space-saving mounting of the filling valve in a cistern is made possible at the same time, since the water pipe and thus the supply line to the pipe are also directly attached to the mounting adapter, which enables the filling valve to be mounted on a mounting device Filling valve can be connected. In addition, the invention is based on the special finding of providing an assembly adapter with the properties mentioned, which can be fixed to the pipe socket is and therefore does not necessarily have to be provided in a cistern when installing the filling valve. Rather, the mounting adapter is only to be fixed to the pipe socket via the nut if it is required for mounting the filling valve in a cistern. In cisterns that have a mounting device that can be attached directly to the pipe socket, the variable design of the set according to the invention enables a water pipe to be fixed directly to the pipe socket via the nut, so that in this case the mounting adapter for mounting the filling valve is not is used. The set according to the invention thus ensures, on the one hand, with the filling valve and with the mounting adapter separate from the filling valve, which can be fixed via the nut to the pipe socket of the filling valve, on the other hand, the mountability of the filling valve on a very large number of known mounting devices of conventional cisterns.

In one embodiment, the cylinder section has two radially opposite flats on its outside. In one embodiment, which can particularly preferably be combined with the aforementioned, the cylinder section has a groove which runs around at least 270 ° of its circumference, in particular completely around its circumference. The provision of corresponding flats or such a circumferential groove brings with it an even greater variability in the connectivity of the mounting adapter to known mounting devices. For example, a clip provided in a large number of conventional mounting devices can engage in the flats or in the circumferential groove, the clip being able to be inserted specifically on the flats or in the groove, depending on the design of the clip provided on the respective mounting device. The cylinder section particularly preferably has the flats and the groove, the flats and the groove being axially offset from one another. It has been found to be particularly advantageous to arrange the groove closer to the pipe socket than the flats, since in the case of a large number of known mounting devices, a bracket corresponding to such a groove is often connected to a support on the pipe socket.

In one embodiment, the connecting section comprises a cylindrical axial section which is arranged in the assembly position within the pipe socket. A support of the mounting adapter on the pipe socket can be particularly supported via this cylindrical axial section, whereby a particularly robust fixation of the filling valve via the mounting adapter to a mounting device in a cistern is made possible. An annular seal is particularly preferably provided between the cylindrical axial section and the pipe socket, via which the pipe socket can be sealed off from the connecting section. Particularly preferably, a groove is provided in the cylindrical axial section of the connecting section, which is arranged on the outside of the cylindrical section around the cylindrical axial section. Such a groove can particularly preferably enable axial fixing of an annular seal, as a result of which a seal between the pipe socket and the connecting section can be ensured in a particularly reliable manner.

In one embodiment, the connecting section has a collar, the radial diameter of which at most corresponds to the outside diameter of the pipe socket, ie is smaller or the same size as the outside diameter of the pipe socket, and which is pressed against an axial end face of the pipe socket in the assembly position. Such pressing of a corresponding collar of the connecting section with the pipe socket can, on the one hand a particularly stable fixation of the connecting section and thus of the mounting adapter to the pipe socket can be guaranteed, and secondly a seal between the connecting section and the pipe socket can be ensured. The corresponding pressing is preferably ensured via the nut, which, as explained, can have an internal thread for this purpose and is screwed onto a corresponding external thread of the pipe socket, for example having projections which point inwards from their internal thread and counter the connection section with its collar press the axial face of the pipe socket. Alternatively, the nut can have a feedthrough for this purpose, through which the cylinder section extends, whereas the collar is arranged within the internal thread and axially offset for feedthrough within the nut and is pressed against the end face of the pipe socket via the nut. Alternatively, for example, the connecting section can be produced integrally with the nut and protrude externally via an external thread of the nut, the nut being screwed with its external thread into an internal thread of the pipe socket and thereby pressing the collar against the end face of the pipe socket.

In one embodiment, the holding section has a holding web along the first radial direction between its two transverse ends. The retaining web is thus arranged in relation to the first radial direction between the two transverse ends. The retaining web extends at the radial end, over which the transverse ends extend in the second radial direction, in the second radial direction beyond the transverse ends. The holding web thus projects in the second radial direction with respect to the transverse ends. The provision of a corresponding footbridge in Combination with the transversal ends enables the mounting adapter to be mounted even more flexibly. This is because the retaining web can be inserted, for example, into a hole-like guide in order to ensure that the mounting adapter is fixed to a mounting device with such a hole-like guide. For example, assembly devices are known in the prior art which have a rail guide and at the same time a hole-like guide. In such assembly devices, for example, holding the rail guide and the holding web in the hole-like guide can be ensured simultaneously via the transverse ends.

According to the invention, the transverse ends are each formed by a rod-like holding area arranged radially outside the cylinder section. The inventors have recognized that such rod-like transverse ends can be inserted particularly well in guides, which are often provided in conventional assembly devices.

The set according to the invention particularly preferably comprises at least one fixing nut which is arranged so that it can be screwed onto the external thread of the cylinder section in the mounting position. In one embodiment, the fixing nut can be placed on an axial end face of the cylinder section and from there screwed onto the external thread in order to reach the assembly position. In particularly preferred embodiments, the set has a plurality of fixing nuts, which are each screwed onto the external thread of the cylinder section in the mounting position. The at least one fixing nut can, for example, enable the mounting adapter to be mounted on a U-shaped or V-shaped mounting device, for example by inserting the cylinder section into the corresponding U-shape or V-shape and the respective shape via the fixing nut is pressed against the nut or the connecting section or the pipe socket. In one embodiment, the fixing can be carried out by pressing a corresponding shape of the mounting device between two fixing nuts arranged on the external thread of the cylinder section by correspondingly screwing the fixing nuts together.

According to the invention, the nut and the mounting adapter are designed as separate components. This increases the flexibility of the assembly of the set according to the invention or of the filling valve via the set according to the invention. According to the invention, the mounting adapter has a first mounting element which comprises the connecting section and the cylinder section, and a second mounting element which comprises the holding section, the first and the second mounting element being designed as separate elements. This staggered construction of the mounting adapter increases the flexibility when installing the filling valve in a cistern. The staggered structure also increases flexibility in the manufacture of the mounting adapter. For example, the first and second mounting elements can be made of different materials. For example, the first mounting element can be made from a metal and the second mounting element from a plastic. In other embodiments, the entire mounting adapter can of course also be made of a metal or a plastic. The second mounting element particularly preferably has a fixing section designed in the manner of a tube, which can be arranged around the cylinder section on the outside in order to reach the mounting position and can be fixed to the first mounting element by means of a fastening means. The cylinder section particularly preferably projects with its from in the mounting position the axial end facing away from the connecting section axially beyond the second mounting element. In this way, accessibility to the end face of the cylinder section can also be ensured if the second mounting element is arranged with its fixing section on the cylinder section and is fixed to the first mounting element. The arrangement of the fixing section around the outside of the cylinder section and the fixing of the fixing section to the first mounting element by means of a fastening means can be carried out in various ways. For example, the fixing section can have an internal thread, which corresponds to the external thread of the cylinder section, the fixing section being screwed onto the cylinder section in the assembly position. In this embodiment, the fastening means are provided via the corresponding threads of the fixing section and the cylinder section. In one embodiment, the arrangement can be carried out by pushing the fixing section axially onto the cylinder section until it rests on the nut or the pipe socket or the fastening section, after which it is then fixed via a fixing nut which is screwed onto the external thread of the cylinder section, so that the fastening means are provided via the interaction of the fixing nut and the external thread of the cylinder section. As an alternative or in addition, such a fixation can take place, for example, via a latching device. It is apparent to the person skilled in the art that the flexibility in the assembly of the filling valve in a cistern is further increased by the separate configuration of the two assembly elements and by the arrangement of the second assembly element on the first assembly element, since the second assembly element only when required, that is to say if appropriate provided mounting device is fixed to the first mounting element and in other mounting devices, the cylinder section is accessible over a wide range if the second mounting element is not is fixed to the first mounting element. Accordingly, by omitting the second mounting element, the cylinder section can be accessible with sections in which it has a groove and / or flats. In general, it should be noted at this point that the various described advantageous embodiments according to the invention can of course be combined with one another, and a combination of the described advantageous embodiment can bring particular advantages. In addition, it should be generally pointed out at this point that the assembly position explained means the specific arrangement of the various elements of the set according to the invention, but that in various embodiments the set also fixes the filling valve in a cistern or in other relative arrangements of its elements to one another. on a mounting device in a cistern.

In one embodiment, the transverse ends of the holding section are each arranged on a radially outer side of the fixing section on a side formed with respect to the first radial direction. In this case, the transverse ends can particularly preferably each be designed as a rod-like holding section, which is arranged on the side of the fixing section on a side formed with respect to the first radial direction. In the particularly advantageous embodiment described, the transverse ends are thus arranged axially along the fixing section, but are arranged radially outside the fixing section.

In one embodiment, the nut has a nut thread corresponding to a thread provided on the pipe socket and a feedthrough and is designed as a component separate from the mounting adapter, the feedthrough having a smaller diameter than that Has nut thread, and wherein the cylinder section in the assembly position is carried out axially by the passage of the nut. The cylinder section can thus be carried out by carrying out the nut. The connecting section is particularly preferably arranged radially inside the nut thread and has a diameter which is larger than the diameter of the bushing. The embodiment described has the advantage that the connecting section can be fixed to the pipe socket via the nut and the cylinder section is accessible for the connection of a water pipe, ie is accessible from its axial end face which faces away from the pipe socket. In one embodiment, the pipe socket has a free axial end to which the nut can be attached and screwed, a retaining flange being formed axially spaced from the free end on the pipe socket. This holding flange enables a further possibility of mounting the filling valve on a mounting device in a cistern. The holding flange preferably has an extension in the first and the second radial direction that is substantially larger, in particular at least twice as large, as the corresponding radial extension of the cylinder section.

The invention further relates to a cistern which has a mounting device which is arranged in an interior of the cistern and is fixed to a wall of the cistern, the filling valve of a set according to the invention being fixed to the mounting device via the mounting adapter of the set. The invention further relates to the use of a set according to the invention for mounting the filling valve on a mounting device of the cistern.

The invention is explained in more detail below with reference to two figures based on exemplary embodiments according to the invention explained.

In Fig. 1 comprehensively the Figures 1a and 1b is an embodiment of a set according to the invention with its components shown schematically in an exploded view. In Fig. 1a are some of the in Fig. 1b components shown compared to Fig. 1b shown in other directions.

In the Fig. 1 The illustrated embodiment according to the invention comprises a filling valve 1. The filling valve 1 has an inlet side which is formed by a pipe socket 10. An external thread is provided on the pipe socket 10. A holding flange 11, which projects radially beyond the pipe socket 10, is arranged axially offset to the pipe socket 10. This in Fig. 1 The set according to the invention also has, as separate components, a nut 2, a first mounting element 3, a second mounting element 4 and a fixing nut 5. In the present case, the first mounting element 3 is made of a metal, in the present case of gunmetal. The first mounting element 3 has a connecting section 31 and a cylinder section 32 arranged axially offset from the connecting section 31. The connecting section 31 has a cylinder-like axial section, in which a circumferential groove 311 is provided, in which an - in the mounting position Fig. 1 not shown - annular seal is used. In the assembly position, the cylinder-like axial section of the connecting section 31 is arranged radially inside the pipe socket 10 of the filling valve 1, whereas the connecting section 31 also has a collar 312, which in the mounting position is pressed by the nut 2 against an axial end face of the pipe socket 10. The pressure of the collar 312 on the end face of the pipe socket 10 by the nut 2 is only used to fix the first mounting element 3 to the filling valve 1. The sealing of the first mounting element 3 relative to the pipe socket 10 and thus relative to the filling valve 1 takes place via the in Fig. 1 Seal, not shown, which rests sealingly against both the inside of the pipe socket 10 and the groove 311 of the connecting section 31. The first mounting element 3 has, in its cylinder section 32, two radially opposite flats 321 and a groove 322 which runs completely around the circumference of the cylinder section 32. The flats 321 on the one hand and the groove 322 on the other hand enable the mounting adapter formed by the first mounting element 3 and the second mounting element 4 to be mounted on different mounting devices in cisterns.

This in Fig. 1 illustrated set according to the invention also has a second mounting element 4, which is made of plastic in the present case. The mounting element 4 has a fixing section 41 designed in the manner of a tube, which has an internal thread which corresponds to the external thread of the first mounting element 3 provided on the cylinder section 32. In the mounting position, the second mounting element 4 is fixed to the first mounting element 3 by the second mounting element 4 being screwed with its fixing section 41 onto the external thread of the cylinder section 32 of the first mounting element 3. The second mounting element 4 also has two transverse ends that lie opposite each other in a first radial direction. These two transverse ends are each formed by a rod-like holding area 42 arranged radially outside the cylinder section. The transverse ends each extend outside of the cylinder section 32 with respect to a first radial direction and extend predominantly over both radial ends of the cylinder section with respect to the second radial direction beyond the respective ends of the cylinder section 32. The second mounting element 4 also has a holding web, which is arranged with respect to the first radial direction between the two holding regions 42 and which extends beyond the holding regions 42 at a radial end of the cylinder section with respect to the second radial direction. The holding web 44 thus extends beyond the holding areas 42 in the second radial direction at one end of the holding areas 42.

The set according to the invention also has a nut 2 which has a nut thread corresponding to the thread provided on the pipe socket 10 and a bushing 20 whose diameter is smaller than the diameter of the nut thread. In the assembly position, the connecting section 31 is located completely within the axial extent of the nut 2, wherein it is pressed against the pipe socket 10 via the flange of the nut 2, which surrounds and forms the bushing 20 of the nut 2. The set according to the invention Fig. 1 furthermore has a fixing nut 5 which has an internal thread which corresponds to the external thread provided on the cylinder section 32. Correspondingly, the fixing nut 5 is arranged so that it can be screwed onto the cylinder section 32 in the mounting position.

In Fig. 2 are different embodiments of an inventive use of the in Fig. 1 shown Sets according to the invention shown in schematic diagrams. Fig. 2 includes the Figures 2a, 2b , 2c and 2d . In each of the figures, a mounting device 61, 62, 63, 64 is shown and the ability of the filling valve 1 to be mounted on the respective mounting device 61, 62, 63, 64 by means of the mounting adapter of the set according to the invention. In the embodiment according to Fig. 2a the mounting device 61 has a clip with a protruding spring 610. The set according to the invention enables the filling valve 1 to be mounted by engaging the cylinder section 32 of the first mounting element 3 in the clamp by the spring 610 engaging in the groove 322 of the cylinder section 32. In this case, in the position of the filling valve 1 mounted on the mounting device 61, a water pipe 6 can be mounted on the end face of the cylinder section 32 via a connector provided on the water pipe 6. Locking the spring 610 in the groove 322 ensures that the filling valve 1 is axially fixed relative to the fixing device 61. In Fig. 2b A mounting device 62 is shown which has a U-shaped section on which the filling valve 1 is to be mounted. As in Fig. 2b The assembly of the filling valve 1 can be carried out by the set according to the invention by passing the cylinder section 32 through the U-shape and pressing the U-shape between two fixing nuts 5, whereby both an axial and a radial fixing of the filling valve 1 relative to the Mounting device 62 is guaranteed. The end face of the cylinder section 32 remains accessible for the connection of a supply line 6 Figures 2a and 2b In the exemplary embodiments shown, the filling valve 1 is installed without using the second mounting element 4 but only with the use of the first mounting element 3. In the exemplary embodiments according to FIG 2c and 2d the filling valve 1 is mounted on mounting devices 63, 64 by means of the first and second Mounting element 3, 4. In the embodiment according to Fig. 2c The mounting device has a rail guide into which the second mounting element 4 with its web-like holding areas forming the transverse ends is inserted, the retaining web 44 of the second mounting element 4 in a hole-like guide of the mounting device in the ultimately achieved fixed position of the filling valve 1 relative to the mounting device 63 63 intervenes. The front side of the cylinder section 32 of the first mounting element 3 remains accessible, so that a water pipe 6 can be screwed onto the cylinder section 32 on the front side and thus connected to the cylinder section and, via this, to the filling valve 1. In the embodiment according to Fig. 2d the mounting device 64 has a circular recess. The filling valve 1 is fixed to the mounting device 64 by means of the second mounting element 4, in that the latching lugs 43 of the second mounting element 4 are locked with the passage of the mounting device 64. How to Fig. 2c explained, the cylinder section 32 of the first mounting element remains accessible for the connection of a water line 6.
