Abstract

A method for removeably fitting a flow control regulator (5) into a plumbing outlet (2) has a cartridge design fitted directly into the outlet and secured by a screw thread. The cartridge locates into the bottom of the outlet bore and has an inlet aperture matching the outlet aperture of the plumbing fitting. This eliminates trapped spaces where debris and impurities could collect. An alternate design has a press fit sleeve inserted into the plumbing outlet to form a grip into which the cartridge is fitted. The cartridge is fitted and removed using conventional tools.

Description

The invention relates to a sanitary outlet fitting with a liquid guide, which opens into a fitting outlet, in the area of which is designed as a Einsetzpatrone designed sanitary functional unit.

Various jet regulators have already been provided, which are provided as a sanitary functional unit in the area of the tap outlet of a sanitary outlet fitting and serve to produce a soft, non-spraying jet of water. The previously known jet regulators can be used regularly in a sleeve-shaped outlet mouthpiece which can be screwed on the end of the valve outlet.

However, the use of a sleeve-shaped outlet mouthpiece, which is to be screwed to the fitting outlet, but requires a complex processing of the outlet fitting and limits beyond the creative freedom in the development of such an outlet fitting. In addition, the outlet nozzle made as a separate and usually chromed metal sleeve is associated with additional, not inconsiderable costs.

Especially in high-quality fittings, which are also esthetically high demands, the fitting and the associated mouthpiece must be ground together with great effort, polished and then also chromed together or painted to smooth as possible transition between fitting and mouthpiece without color deviations and without to reach disturbing gaps and to ensure equal diameters.

The usual in the use of conventional mouthpieces column between the valve and the screwed onto the outlet end of the valve mouthpiece can not only disturb the visual appearance of such a valve, but also form a hygienic vulnerability by dirt accumulation.

There is therefore in particular the task of creating a sanitary outlet fitting that can be used without significant restriction of the design scope with a jet regulator or other sanitary function unit.

The achievement of this object is in the sanitary outlet fitting of the type mentioned in particular that the liquid guide is adapted at least in the mouth region of the fittings spout in their clear cross section of the Einsetzpatrone, and that the Einsetzpatrone from the mouth side in the fittings spout can be used and kept detachable.

The designed as Einsetzpatrone functional unit can be used from the outlet side in the fitting outlet and kept detachable therein. To accommodate this Einsetzpatrone the liquid management of the outlet fitting is adapted in its clear cross section at least in the mouth region of the fitting outlet to the Einsetzpatrone. On an associated with additional, not inconsiderable costs outlet nozzle can thus be dispensed with; Such mouthpieces were previously associated with a disproportionately high proportion of the total cost of an outlet fitting. Since the screwing of such an outlet mouthpiece is dispensable and since such an outlet mouthpiece for color matching also does not have to be processed together with the outlet fitting, the production of the sanitary outlet fitting is much easier. As for a mouthpiece can be dispensed with, the usual gap between mouthpiece and outlet fitting are also avoided when using conventional mouthpieces, which would otherwise be visually distracting and would preclude high hygienic requirements. The sanitary function unit is detachably held in the tap outlet of the sanitary outlet fitting and can thus be easily removed and removed by the untrained user for service work, such as for removing dirt or for descaling. By dispensing with an outlet mouthpiece and the creative scope in the development of an outlet fitting is increased, so that, for example, even colored outlet fittings are possible without that special mouthpieces would have to be produced in appropriate color with additional costs.

It is expedient if the insert cartridge with at least the predominant portion of its longitudinal extent, preferably completely with its entire longitudinal extent, is arranged in the fitting outlet. If the insert cartridge is completely arranged with its entire longitudinal extension in the fitting outlet, it can be hidden, i. From the outside virtually invisible and tamper-proof in the fitting spout are housed. From there, the insertion cartridge, for example, with the help of a crown or fork wrench or other removal tool when needed to solve again.

The insert cartridge can be held directly, without additional adapter in the fitting spout. Another embodiment according to the invention provides that the insert cartridge is held by means of a preferably sleeve-shaped intermediate holder in the fitting outlet.

In order to facilitate the installation of the insert cartridge in the fitting outlet and to determine there the position of the insert cartridge, It is expedient if the insert cartridge or the intermediate holder can be used up to an insertion stop in the fittings spout.

It is possible that the insertable from the outlet side in the fitting outlet intermediate holder is releasably or permanently held in the fitting outlet.

It is advantageous if the intermediate holder is held in the fitting outlet by means of an adhesive, clamping, latching and / or screw connection and / or by pressing, clawing or wedging. It is advantageous if the intermediate holder relative to the inner peripheral wall of the fitting outlet is preferably circumferentially sealed. The sealing of the intermediate holder in the outlet fitting can be achieved by means of additional seals such as e.g. O-ring or gasket, by means of molded to the intermediate holder seals or by means of the connecting means, for example by the adhesive used in the bonding of the intermediate holder, take place.

It is advantageous if the insert cartridge is held in the fitting outlet or in the intermediate holder by means of a clamping, latching or screw connection. Thus, the cartridge can be kept, for example, by a single or multiple threaded or by snaps and thus by such releasable connections in the outlet fitting or the intermediate holder, which allow a simple and rapid assembly and disassembly of the functional unit, if necessary.

It is expedient if the insertion cartridge is sealed against the intermediate holder or the inner peripheral wall of the fitting spout. Such a sealing of the functional unit with respect to the intermediate holder or the inner peripheral wall the valve spout can be done for example via an O-ring, a flat gasket or other known seals.

In this case, a preferred embodiment according to the invention provides that for sealing between Einsetzpatrone or intermediate holder on the one hand and the outlet fitting on the other hand, at least one ring seal, preferably at least one O-ring is provided.

After a further development proposal according to the invention it is provided that the insert cartridge or the intermediate holder carries an external thread which can be screwed into an internal thread in the fitting outlet, and that the external thread and the internal thread are dimensioned and arranged such that the thread when screwing the Insertion cartridge or the intermediate holder grip each other in a relative position of the outlet fitting on the one hand and insert cartridge or intermediate holder on the other hand, in which the outside of the cartridge or the intermediate holder provided on the O-ring or the like ring seal the outlet fitting is not frictionally touched. The arrangement of the ring seal which seals the cartridge radially in the valve body, a significant advantage can be used during assembly and disassembly: When mounting one has significantly more feeling for finding the thread, since the ring seal is then pressed radially, if the thread has already been found. By pressing the ring seal much friction is generated, which would otherwise make the feeling of mounting otherwise difficult. When disassembling the selected arrangement of the ring seal has the advantage that the insert cartridge with the help of the insertion and removal tool is unscrewed from the screw with the fitting outlet. As long as the ring seal is still in the compressed state, there is an axial forced movement through the thread. Only when the ring seal has left the valve seat in the axial direction, the thread comes out of engagement. This has the distinct advantage that you can completely remove the designed as a hidden insert cartridge and optionally mounted with an intermediate holder functional unit by rotating movement of the valve and not because of friction must additionally pull axially or requires the support of water pressure.

It is also possible that at least one circumferential seal is integrally formed on the insert cartridge, wherein the insert cartridge in the sealing area can be configured not only as a multi-component injection molding, but in particular as a one-component injection molding.

A particularly advantageous development according to the invention of its own worth-worth protection therefore provides that the insert cartridge and / or the intermediate holder is integrally connected to at least one circumferentially sealing between the Einsetzpatrone or the intermediate holder on the one hand and the outlet fitting on the other hand. The provided on the cartridge and / or the intermediate holder and integrally molded seal prevents creepage or leakage currents flowing through the outlet fitting fluid u.a. between the insert cartridge or the intermediate holder on the one hand and the outlet fitting on the other.

It may be advantageous if the inflow-side end edge region of the insert cartridge and / or the intermediate holder is designed as a sealing profile. Such a configuration can also be designed with a comparatively wide end edge be without the clear outer cross section is thereby restricted too much. This comparatively wide end edge on the insertable cartridge and / or the intermediate holder can then be used very well for the design of a comparatively complex sealing profile.

In the execution of the sealing profile, it is expedient if the sealing profile has at least one surface and / or a lip seal. These forms of the sealing profile can effect an effective seal together with the counter-stop of the outlet fitting, when the sealing profile acts on the counter-stop and thereby a line or / or surface pressure is exerted on the sealing profile.

In order to prevent excessive deformation of the sealing profile, it is expedient if the insert cartridge and / or the intermediate holder on the inflow side have an insertion stop which limits a deformation of the sealing profile in the position of use. Otherwise, the sealing profile could be damaged or excessively deformed, which could lead to leakage in the area between insert cartridge or intermediate holder and outlet fitting and thus to corresponding leakage currents.

In the design of the sealing profile, it is advantageous if the sealing profile has at least one seal with a sealing profile base, which is designed as an insertion stop. The sealing profile can be arranged on the upper boundary surface of the sealing profile base. The insertion stop can be used to limit the screwing depth when attaching the insert cartridge or the intermediate holder to the valve, for example via a screw. If screwing is done manually without tools, the insertion stop can provide a feeling of firmness of the screw connection by: the impact of the counter-attack on the valve by the insertion stop is noticeable.

In order to use as large an area as possible of the clear cross section of the insertable cartridge or of the intermediate holder or to unnecessarily narrow the clear cross section, it is expedient if the sealing profile and optionally its insertion stop cooperate with a front edge region of the outlet fitting which delimits the clear cross section the insert cartridge and / or the intermediate holder simultaneously serves as a counter-stop.

It is particularly advantageous for the function of the insertion stop when the insertion stop is arranged adjacent to the sealing profile in the radial direction. Thus, the insertion stop can accurately absorb the forces that could possibly damage the sealing profile. In addition, a space-saving arrangement of the insertion stop and the sealing profile can thus be achieved on the clear cross section of the jet regulator.

A simple, yet effective sealing design of the sealing profile is that the sealing profile has at least one annular circumferential sealing lip. This sealing lip can be designed either elastic and flexible and thereby adapt to the counter stop in the outlet fitting when attaching the insertable cartridge and / or the intermediate holder, or the sealing lip is designed so that deformation is difficult, so that the sealing lip when mounting only seals by a surface pressure through the counter-stop of the outlet fitting. These two possibilities can be combined with several sealing lips in different ways.

A particularly advantageous embodiment of the sealing profile provides that the sealing profile has at least two annular circumferential sealing lips, which are successively effective with increasing, acting on the jet regulator insertion pressure. This graduated design of the sealing profile can cause the adjacent sealing lips of the sealing profile are effective in case of failure of a sealing lip. In addition, by tightening the bolted to the outlet fitting component, i. the insert cartridge or the intermediate holder, an insertion pressure are exerted, such that at least other seals of the sealing profile can be effective.

Another embodiment with ringfömig circumferential and successively become effective sealing lips provides that these sealing lips have different heights. It is possible after prolonged use of Einsetzpatrone and / or the intermediate holder to sustain the sealing effect by tightening the bolted to the outlet fitting component long-term. If the highest sealing lip has already become slightly damaged or worn or inflexible, the sealing lip closest to the height can reach the sealing effect again after tightening. In addition, any small bumps of the counter-stop of the outlet fitting can be compensated. It may be advantageous if the sealing lips have stepped heights and if the highest sealing lip forms the innermost or outermost seal of the sealing profile.

It is possible that the component having the seal of the insert cartridge and / or the intermediate holder is made as a multi-component injection molded part, and that this component in the region of at least one seal made of a flexible and / or elastic material. For easy recycling of the insert cartridge and / or the intermediate holder forming Materials, however, it is expedient if the seal and the component of the Einsetzpatrone and / or the intermediate holder integrally connected to the same, preferably food-safe material are made. In this case, the production costs can be simplified and the tool costs for a possibly required injection molding tool can be kept comparatively low.

A preferred embodiment according to the invention provides that the sanitary functional unit is designed as a jet regulator.

Further features of the invention will become apparent from the following description of inventive embodiments in conjunction with the claims and the drawings. The individual features may be implemented individually or in combination in an embodiment according to the invention.

In the figures 1 and 2, a sanitary outlet fitting in two different versions 1, 2 is shown. The outlet fittings 1, 2 have a liquid guide 3, which opens into a valve outlet 4. In the area of this fitting outlet 4, a sanitary functional unit 5 is provided, which serves as a jet regulator here. Serving as a jet regulator functional unit 5 is designed as Einsetzpatrone, in the interior of which at least one jet decomposing device and a Strahlreguliereinrichtung are provided.

From the figures 1 and 2 it is clear that the insert cartridge 5 is inserted from the outlet side of the outlet fitting 1, 2 of such in the fittings outlet 4 and releasably held therein that the insert cartridge 5 here completely and with their entire longitudinal extent practically invisible in Faucet outlet 4 is arranged.

While the insert cartridge 5 of the outlet fitting 1 shown in Figure 1 can be used directly in the fittings outlet 4, the insert cartridge 5 of the outlet fitting 2 shown in Figure 2 is held indirectly via a sleeve or cup-shaped intermediate holder 6 in the fitting outlet 4.

This intermediate holder 6 may be releasably or permanently attached in the fitting outlet 4. It is possible to attach the intermediate holder 6 in the fitting outlet 4, for example by means of a clamping, latching and / or screw connection. If the intermediate holder 6 glued in the fitting outlet 4, the adhesive used can also be used as a sealing means for sealing the intermediate holder 6 relative to the inner peripheral wall of the fitting outlet 4. In such an embodiment, in which the intermediate holder 6 is permanently attached in the outlet fitting 2, the intermediate holder 6 can be introduced from the valve manufacturer in a simple manner in the outlet fitting 2, to subsequently remain throughout the life of the outlet fitting 2 therein. The insert cartridge 5 is releasably secured in the outlet fitting 2 in the intermediate holder 6 to be removed from the outlet fitting 2 when needed, such as for service work to remove dirt or for descaling by the user.

The outlet fittings 1, 2 shown here can be produced without much effort and with comparatively low costs. As is clear from Figure 2, can be dispensed with a special processing of the particular for receiving the intermediate holder 6 fitting outlet. An additional cost reduction is achieved by eliminating the previously required outlet mouthpieces.

In the figures 1 and 2 it is shown that the processing of the outlet fitting in the area of the intended for receiving the sanitary functional unit valve outlet, for example by designing a simple blind hole or a blind hole with a simple holding geometry, such as a groove, is possible. With appropriate design of the provided between the functional unit 5 and outlet fitting 1, 2 holding mechanism may possibly even be dispensed with machining of the outlet fitting.

The attachment of the intermediate holder 6 in the valve outlet 4, for example by means of pressing, gluing, snap, Verkrallen or wedging done. The sealing of the intermediate holder 6 in the fitting outlet 4 is possible, for example with additional seals, such as O-ring or flat gasket, to the intermediate holder 6 molded seals or by the above-mentioned connecting means, such as the adhesive used in the bonding.

In the figures 1 and 2 it can be seen that the insert cartridge 5 is releasably secured here by means of a screw in the outlet fittings 1, 2. For mounting the cartridge different variations are possible, such as single or multi-threaded screw, snaps or other releasable connections that allow easy assembly and disassembly.

In the outlet fitting shown in Figure 1, the insert cartridge 5 directly in the mouth region of the valve outlet 4, without the interposition of an intermediate holder 6, was added. For this purpose, the outlet fitting 1 shown in FIG. 1 has, in the region of its fitting outlet 4, an internal thread into which the insert cartridge 5 is screwed in from the mouth side can be. In this case, trained as a jet regulator insert cartridge 5, for example, by a crown key, which acts on the Außenkontor the insert cartridge between the longitudinal webs, be screwed. An assembly and disassembly of certain for the outlet fittings 1, 2 insert cartridges 5 is also possible via standardized or special tools that are recognized on the lower end face of the insert cartridge 5 to screw the insert cartridge, for example, in the outlet fitting 1, 2.

FIG. 3 shows a sanitary outlet fitting 2 in the region of the fitting outlet 4 of its liquid guide 3. In the area of the fitting outlet 4, a sanitary functional unit equipped as insert cartridge 5 is provided, which is held in the fitting outlet 4 via a sleeve-shaped intermediate holder 6. The insert cartridge 5 can be inserted from the inflow side of the intermediate holder 6 up to a holding shoulder 7 in the intermediate holder 6. The intermediate holder 6 has at its downstream peripheral edge region on an external thread 8, which external thread 8 is screwed into a complementary internal thread in the fitting outlet 4 such that the intermediate holder 6 and the insert cartridge 5 located therein with its entire longitudinal extent completely arranged in the fittings outlet 4 are.

On the side facing away in the flow direction side of the external thread 8, an annular groove 10 held in a ring groove 11 is provided on the intermediate holder circumference, which seals in the radial direction between the intermediate holder 6 and the inner circumference of the outlet fitting 1. The insert cartridge 5 is formed here from a downstream jet regulator 12, which is preferably detachably connected on the inflow side with a flow rate regulator 13 and with an upstream front screen 14.

On the upstream side of the intermediate holder 6, a further attachment screen 15 is provided which can extend in the interior of the liquid guide 3 of the outlet fitting 2 over a comparatively large cross-section. The front screen 15 is releasably connected to the intermediate holder 6 and has at its peripheral edge on a circumferential latching projection 16 which engages in an annular groove on the inflow-side inner periphery of the intermediate holder 6. Between the front screen 15 and an inflow-side end face of the jet regulator 12 of the Einsetzpatrone 5 a sealing ring in the axial direction seal 17 is provided, wherein the jet regulator 12 is held with an annular flange 18 between the holding shoulder 7 and the attachment screen 15. In the intermediate holder 6 functional units of conventional design can be used, which can be configured, for example, as a jet regulator, flow rate regulator, backflow preventer and / or attachment screen.

FIG. 4 shows a sanitary outlet fitting 1, in the outlet end of which a sanitary functional unit designed as an inserting cartridge 5 can also be inserted without an intermediate holder. The insert cartridge 5 has a multi-part and here two-part designed cartridge housing 19 which carries an external thread 21 on a downstream housing part 20. The insert cartridge 5 is screwed to this external thread 21 with an internal thread, which is arranged on the inner periphery of the provided at the outlet end of the outlet fitting 1 liquid guide 3. Also on the housing part 20, a ring seal 11 is provided on the side facing away in the flow direction side of the external thread 21, which is located in an annular groove on the outer circumference of the cartridge housing 19.

Also, the insert cartridge 5 in Figure 4 is with their entire Longitudinal extent substantially completely arranged in the valve outlet 4. Also, the insert cartridge 5 has a downstream jet regulator 12, which has a jet splitter 22 and a subsequent Strahlreguliereinrichtung 23. The jet regulator 12 is connected on the inflow side to a flow rate regulator 13, which is preceded by a front screen 14.

Due to the multi-part design of the cartridge housing 19, the insert cartridge 5 in Fig. 4 is designed like a box. While the housing part 20 allows the installation of the insert cartridge without intermediate holder 6 and without mouthpiece in an outlet fitting 1, alternatively, another, not shown, downstream housing part may be provided without external thread, which serves for installation of the insert cartridge 5, for example, in a conventional mouthpiece.

While the left halves of the longitudinal sections shown in Fig. 3 and 4 show the installation of Einsetzpatronen in a configured as a casting outlet fitting, it is shown in the right half of Figure 3 and 4, that these Einsetzpatronen be installed in a mouth side designed as a metal pipe outlet fitting can.

In FIGS. 3 and 4 it is indicated that the intermediate holder 6 in FIG. 3 and the insert cartridge 5 in FIG. 4 have a contoured outflow end face formed by projections and depressions 24, this contouring being designed as a tool engagement surface, for example for a complementarily shaped insertion tool , It may possibly serve as an insertion tool and a conventional coin piece.

In contrast, a similar to Figure 4 outlet fitting 1 is shown in Figure 5, the cartridges assigned 5 are, of which a Einsetzpatrone 5 is in the outlet fitting 1, while a structurally identical other Einsetzpatrone 5 'is provided for replacement. From Figure 5 it can be seen that the outflow end face of each insert cartridge 5, 5 'has a contour formed from the end edge projections and recesses 24 contouring, such that the recesses 24 of the held in the outlet fitting 1 Einsetzpatrone 5 as a tool engaging surface for the projections 25 of the Exchange specific and used here as an insertion tool other insert cartridge 5 'serve and vice versa. The projections 25 and the depressions 24 at the outflow end face of the insert cartridges 5, 5 'each form a crown-like lower edge, the jaws of which fit into the respective counterpart to be assembled or disassembled.

While a complete insertion cartridge 5 'is used in FIG. 5 for replacing the insertion cartridge 5 located in the outlet fitting 1, it is also possible to unscrew the insertion cartridge 5 or the intermediate holder 6 located in the outlet fitting merely by means of a further intermediate holder 6 or just another one Cartridge housing to use an otherwise not supplied insert cartridge. For this purpose, the manufacturer of fittings only one additional intermediate holder or just another cartridge housing with the fitting mitermose, which are intended as an insertion tool. This has the advantage that the valve manufacturer does not have to provide a second, in the outlet fitting mounted unit and the other intermediate holder or the other cartridge housing, which are manufactured and used in relatively large numbers, a very inexpensive auxiliary tool.

In Figure 6, an outlet fitting 2 is shown in the means of an intermediate holder 6 a comparable with Figure 3 insertable cartridge 5 can be used. While an intermediate ring seal 11 designed as an O-ring is provided on the intermediate holder 6 shown in FIG. 3, a seal 30 is integrally formed on the insertion cartridge 5 instead of on the inflow side thereof. The integrally formed on the inflow-side end edge region of the cartridge housing seal 30 is designed as a sealing profile, which has a sealing lip 31 and a parallel outer circumferential insertion stop 32. The insertion stop 32 limits in the position of use of the insert cartridge 5 a deformation of the seal 30 and its sealing profile. In the position of use, the sealing profile with the sealing lip 31 and its insertion stop 32 cooperate with a circumferential on the inner circumference of the valve outlet ring shoulder 33, which limits the clear outlet cross-section of the outlet fitting 2. The cartridge case of the insert cartridge 5 with the integrally formed thereon seal 30 can be prepared as a one-component or multi-component injection molded part. For the simple recycling of the materials used for the insert cartridge and its intermediate holder, however, it is expedient if the cartridge housing and the molded-on seal 30 are made of the same, preferably food-safe material. As a result, the production costs can be simplified and the tool costs for a possibly required injection molding tool can be kept comparatively low.

As is clear from a comparison of Figures 3 and 6, the insert cartridge 5 shown in Figure 6 structurally much simpler to design, since the configured in Figure 3 as an inflow side snap ring additional attachment screen 15 and the ring seals 11 and 17 can be omitted, which assembly technology and manufacturing technology is much easier.

The seal 30 of Figure 6 is shown in Figure 7 in a detail longitudinal section shown. The sealing lip 31 as well as the peripheral circumferential outer insertion stop 32 are clearly visible.

9 shows a modified embodiment of the seal 30 is shown, the sealing profile is designed here as a surface seal.

In contrast, FIG. 8 shows an embodiment with a single sealing lip 31 which is arranged on a sealing profile base 31a. In this case, the sealing profile base 31a is configured as an insertion stop 32 which, in the embodiments of the seal 30 shown in FIGS. 6 and 7, limits the insertion depth of the insertion cartridge in the outlet fitting.

Figures 10 and 11 show two embodiments of the sealing profile designed as a seal 30, each with two sealing lips 31, which are arranged circumferentially annular in the inflow-side end edge region of the insert cartridge. 10, the flanks of the sealing lips 31 are chamfered differently in order to influence the deformation in the position of use. The opposite sloping flanks shown in FIG. 10 cause the sealing lips 31 to deflect apart in the position of use of the inserting cartridge and thus also to seal off a wide end edge area. FIG. 11 shows two sealing lips 31 which each have bevels on their outer side and are thereby bent in the position of use of the insertion cartridge towards the center of the insertion cartridge.

In Figure 12, an advantageous embodiment of the seal 30 is shown, being provided on the sealing profile base here annular circumferential and successively become effective sealing lips 31 are, which are arranged stepwise to each other and have different graded heights. These sealing lips 31 are successively effective with increasing, acting on the Einsetzpatrone insertion pressure. It is possible after prolonged use of Einsetzpatrone to maintain the sealing effect by tightening the Einsetzpatrone and / or the intermediate holder long-term. If the highest sealing lip 31 arranged here on the outer peripheral edge has already become somewhat damaged or worn or become inflexible, the sealing lip 31 closest to the height can reach the sealing effect again after tightening. In addition, any small bumps of the counter-stop in the outlet fitting can be compensated.

It is understood that the sealing profiles described with reference to FIGS 7 to 12 can be integrally formed not only on a Einsetzpatrone, but also on an intermediate holder, in particular on the inflow-side end edge.

The sanitary functional units shown here are used in such a way in the outlet end of a sanitary outlet fitting 1, 2, that can be dispensed with a screw-on from the outside to the outlet end mouthpiece. Since it is possible to dispense with a mouthpiece in the outlet fittings shown here, also eliminates the otherwise remaining between the mouthpiece and outlet fitting gap that affects the appearance of such outlet fitting and precludes contamination by dirt hygienic requirements. Since the Einsetzpatrone is arranged in the outlet fittings 1, 2 shown here with their entire longitudinal extent completely in the liquid guide the outlet fitting, the outlet fitting can be uniformly colored or chromed without much effort, without at the same time a mouthpiece or other components in the same Color or shape to edit. Since the entire clear cross section of the liquid guide provided in the outlet fitting is available for the insert cartridge, large-area attachment screens can also be used, which significantly extend the service life between two maintenance intervals. If the insert cartridge - as shown in Figure 5 - designed on its downstream side so that with her a structurally identical, but intended for replacement insert cartridge and can be screwed again, the Einsetzpatrone also serves as a tool for assembly and disassembly.
