Description
Opfindelsen angår en indsats til et sanitært armatur af den i krav 1' indledning angivne art.The invention relates to an insert for a sanitary fixture of the kind set forth in claim 1 '.
l DK 173504 B1l DK 173504 B1
Ved en sådan kendt indsats (DE 36 23 585 Al) er der i gennemstrømningskanalen af den af ventilmekanismens faste styreskive dannede bunddel af indsatsen indsat et hulcylin-5 drisk tætningselement, som strækker sig i annaturliuset, ind til den med gennemstrømningskanalen flugtende tilstrømningskanal. Tætningselementet er såvel i forhold til gennemstrømningskanalvæggen som også i forhold til tilstrømningskanalvæggen kun tætnet i radial retning ved hjælp af hver en tætningsring. Indsatsen sidder på armaturhusets bundflade og er fastlagt i aksial retning ved hjælp af en i armaturhuset indskruet gevind-10 ring. Ventilmekanismen i indsatsen er indstillelig forspændt ved hjælp af en i indsatshuset indskruet spændring.By such a known insert (DE 36 23 585 A1), a hollow cylindrical sealing element extending in the annature loop into the flow channel which is flush with the flow channel is inserted in the flow channel of the bottom part of the valve mechanism formed by the valve mechanism fixed by the valve mechanism. The sealing element is only sealed in radial direction with respect to each sealing ring in relation to the flow channel wall as well as in relation to the flow channel wall. The insert sits on the bottom surface of the luminaire housing and is fixed in the axial direction by means of a threaded screw threaded into the luminaire housing. The valve mechanism in the insert is adjustably pre-tensioned by means of a tension screw inserted in the insert housing.
Med denne kendte indsats er der ganske vist sikret en pålidelig tæt fluidumforbindelse mellem indsatsen og arraaturhuset, men ved indsatsens montering skal indstillingen af tætningskræfteme i ventilmekanismen foretages ved drejning af spændringen til opnåelse 15 af en uforanderlig forspænding. Men ved seriefremstilling er det vanskeligt at opnå en uforanderlig forspændingsværdi fra indsats til indsats. Derfor kan ventilmekanismens tætningskræfter og dermed også betjeningskræfterne for ventilmekanismen variere væsentligt. Ved indsatsens drift falder den over spændringens spændkrafter frembragte forspændingskraft og dermed ventilmekanismens tætningskræfter desuden stejlt som 20 følge af dens slid. For at opnå en upåklagelig drift skal spændringen derfor efterstilles til slidudligning, hvilket kræver nogen montageudgift og passende værktøj.With this known insert, a reliable close fluid connection between the insert and the arator housing is assured, but when installing the insert the adjustment of the sealing forces in the valve mechanism must be made by turning the tension ring to obtain an invariable bias. But in series production, it is difficult to obtain an invariable bias value from effort to effort. Therefore, the sealing forces of the valve mechanism and thus also the operating forces of the valve mechanism can vary considerably. In the operation of the insert, the biasing force produced by the tension ring of the clamping ring and thus the sealing forces of the valve mechanism also fall steeply as a result of its wear. Therefore, in order to achieve impeccable operation, the clamping ring must be reset to wear equalization, which requires some mounting expense and appropriate tools.
Opfindelsen har derfor til formål at tilvejebringe en indsats af den indledningsvis angivne art, som ved upåklagelig tætning i forhold til armaturhuset, hvad angår ventilmekanismens tætningskræfter, ikke behøver at indstilles ved monteringen og arbejder pålidelig 25 og let bevægelig uden efterindstillingskrav over et langt tidsmm.The invention therefore aims to provide an insert of the kind initially provided, which, with impeccable sealing relative to the housing of the valve mechanism, does not need to be adjusted during mounting and operates reliably and easily movable without long-term requirements.

Denne opgave bliver løst ved hjælp af de i patenikrav 1 angivne træk. Fordelagtige videreudviklinger er angivet i underkravene 2 til 8 og ligeledes forklaret i det efterfølgende.This task is solved by means of the features specified in Patent Claim 1. Advantageous further developments are set out in subclaims 2 to 8 and also explained below.
Med udgangspunkt i teknikkens allerede angivne stade er indsatsens bunddel ifølge 5 opfindelsen forsynet med en modboring, so.n åbner sig i retning mod armaturhusets bundflade, i hvilken modboring der er anbragt en rørformet, fjederelastisk elementdel, som rager frem fra bunddelen i retning mod bundfladen for at forbinde tilstrømningskanalen med gennemstrømningskanalen, såvel radialt som også aksialt fluidumtæt og samtidig forspænde indsatsen via ventilmekanismen mod armaturhuset, for at holde de 10 enkelte komponenter af indsatsen i kontakt under en bestemt forspænding.Based on the state of the art already stated, the bottom part of the insert according to the invention is provided with a counter bore, thus opening in the direction towards the bottom surface of the luminaire housing, in which counter-bore is a tubular spring elastic element part projecting from the bottom part towards the bottom surface. to connect the inflow duct with the flow duct, both radially and axially fluid tight, and at the same time bias the insert via the valve mechanism to the luminaire housing, to keep the 10 individual components of the insert in contact during a particular bias.
Dermed er der ifølge opfindelsen kun tilvejebragt en del, nemlig den rørformede, fjederelastiske elementdel, som samtidig opfylder funktionerne med tætningen af vandtil-føringeme til indsatsen og det såvel radialt imod modboringeme i indsatsens bunddel som også aksialt imod armaturhusets bundflade, og indsatsens forspænding. Den rigtige 15 forspændingskraft til ventilmekanismens tætningskræfter og en let bevægelig styredrift af indsatsen kan let fastlægges ved egnet valg af den elastiske elementdels fjederkarakteristik og fremkommer af sig selv ved indsatsens indbygning i armaturhuset. Også ventilmekanismens slid fra den Qederelastiske elementdel bliver udlignet uden efterind-stillingskrav, mens de enkelte komponenter af indsatsen i indbygget tilstand stadig bliver 20 holdt under tilstrækkelig forspænding.Thus, according to the invention, only a part is provided, namely the tubular spring elastic element part, which simultaneously fulfills the functions of sealing the water supply to the insert and that both radially against the counter bores in the bottom part of the insert as well as axially against the bottom surface of the luminaire housing and the bias of the insert. The correct biasing force for the sealing forces of the valve mechanism and an easily movable control operation of the insert can be easily determined by suitable selection of the spring characteristic of the elastic element and is evident by the insertion of the insert into the housing. Also, the wear of the valve mechanism from the spring-elastic element part is offset without post-adjustment requirements, while the individual components of the insert in the built-in state are still kept under sufficient bias.
Ifølge krav 2 er den rørformede elementdel dannet af elastomert materiale og forsynet med en indsnævret ende, som danner en skulder for understøtningen af enden af en skruetrykfjeder, som er indført i den rørformede elementdels indre. Som angivet i krav 3 er det også muligt at anvende en af elastomert materiale dannet rørformet elementdel, 25 som ved hjælp af sin egen forspændingskraft frembringer den elastiske forspænding. I dette tilfælde er fjedrene, som belaster tætningerne, dannet af selve tætningerne. Desuden er det muligt at forme de elastomere rørformede elementdele således, at trykket af DK 173504 B1 3 det deri flydende vand til tilbøjelighed til at deformere dem og til at foranledige dem til at forspændes med yderligere kraft til frembringelse af en virksom tætning mod armaturhuset (krav 4).According to claim 2, the tubular member portion is formed of elastomeric material and provided with a constricted end which forms a shoulder for supporting the end of a helical spring which is inserted into the interior of the tubular member member. As stated in claim 3, it is also possible to use a tubular element member formed of elastomeric material which produces its elastic bias by means of its own biasing force. In this case, the springs which strain the seals are formed by the seals themselves. In addition, it is possible to mold the elastomeric tubular member portions such that the pressure of DK 173504 B1 3 the liquid water therein tends to deform them and to cause them to bias with additional force to produce an effective seal against the fixture housing (claim 4).
Alternativt kan den rørformede elementdel ifølge krav 5 være fremstillet af et i det 5 væsentlige stift materiale og være forsynet med deformerbare O-ringe, som tætner radialt mod indsatsens modboringer og ligger frontalt an ved armaturhusets bundflade.Alternatively, the tubular member portion of claim 5 may be made of substantially rigid material and be provided with deformable O-rings which seal radially to the counter bores of the insert and abut front to the bottom surface of the luminaire housing.
Det elastiske element til den rørformede elementdels forspænding kan her være en skruetrykfjeder (krav 6) eller det kan være udformet som et fjedrende elastomert hylster (krav 7). I sidstnævnte tilfælde kan hylsteret være udformet på en sådan måde, at det 10 deri herskende vandtryk har tilbøjelighed til at deformere det, hvorved fortrinsvis den på den rørformede elementdel indvirkende forspændingskraft bliver forøget (krav 8).The elastic member for the bias of the tubular member may here be a helical spring (claim 6) or it may be formed as a resilient elastomeric sleeve (claim 7). In the latter case, the sheath may be designed such that the prevailing water pressure tends to deform it, thereby preferably increasing the biasing force acting on the tubular member portion (claim 8).

Som det er vist i figur 1 har armaturet et armaturhus 1 af metal, i hvis indre et hulrum eller et kammer 2 er dannet til optagelse af en indsats. Tilstrømningskanaler 4 og 5 for 5 varmt og koldt vand er dannet i huset 1 og ender i kammerets 2 bundflade 3. Der er tilvejebragt et ringformet kammer 6 for at optage det blandede vand fra indsatsen og på konventionel måde føre det til et udløb (ikke vist). Huset 1 er lukket ved hjælp af en skruekappe 8, som ligger an mod huset 1 og tætner dette ved hjælp af en elastisk 0-ringtætning 7.As shown in Figure 1, the luminaire has a metal luminaire housing 1, the inside of which a cavity or chamber 2 is formed to receive an insert. Inflow ducts 4 and 5 for 5 hot and cold water are formed in the housing 1 and end in the bottom surface 3 of the chamber 2. An annular chamber 6 is provided to receive the mixed water from the insert and in a conventional manner lead to an outlet (not shown ). The housing 1 is closed by means of a screw cap 8 which abuts the housing 1 and seals this by means of an elastic 0-ring seal 7.
10 Indsatsen har et indsatshus 9 med en bundtle: 10 med gennemstrømningskanaler 11 og 12 for indføringen af varmt og koldt vand. Gennemgangen 13 tjener som udgang for det blandede vand fra indsatshuset 9 til armaturhusets I ringformede kammer 6. En fast styreskive 16, som er fremstillet af et hårdt materiale som stift formstof eller keramik, er anbragt i indsatsens bunddel 10 og fastgjort ved hjælp af en skrue 21. En tætning 22 15 ligger sammentrykket under styreskiven 16. Den faste styreskive 16 er med sine nederste gennemgange 17 og 19 i flugt med bunddelens 10 gennemstrømningskanaler 11 og 12 til indføringen af koldt og varmt vand. Foroven fører gennemgangene 17 og 19 til hulrummene 18 eller 20 til fordelingen af vand i samvirke med en af et hårdt materiale fremstillet bevægelig styreskive 23. Styreskiven 23 er anbragt over den faste styreskive 20 16 og kan ved hjælp af en føring 24 i en drejelig drivring 25 bevæges translatorisk og roterende mellem bestemte ved hjælp af huset definerede grænsestillinger. En nedre ved indsatshuset 9 tilsluttet lejehalvdel 26 er støttet mod armaturhusets 1 kappe 8 og danner en sædehalvdel for en styrekugle 27. Fra ki.glen 27 strækker sig en indre arm, som griber ind i føringen 24, og en ydre arm 29, som er tilsluttet til betjeningsarmen 30.10 The insert has an insert housing 9 with a bundle: 10 with flow channels 11 and 12 for the introduction of hot and cold water. The passage 13 serves as the outlet for the mixed water from the insert housing 9 to the annular chamber of the luminaire housing 6. A fixed guide disc 16, which is made of a hard material such as rigid plastic or ceramic, is placed in the bottom part 10 of the insert and secured by a screw. 21. A seal 22 15 is compressed under the guide disc 16. The fixed guide disc 16, with its lower passages 17 and 19, is flush with the flow channels 11 and 12 of the bottom part 10 for the introduction of cold and hot water. Above, the passageways 17 and 19 lead to the cavities 18 or 20 for the distribution of water in cooperation with a movable guide disc 23 made of a hard material. The guide disc 23 is arranged over the fixed guide disc 20 16 and can by means of a guide 24 in a rotatable drive ring 25 is translationally and rotationally moved between certain boundary positions defined by the housing. A bearing half 26 connected to the insert housing 9 is supported against the sheath 8 of the housing housing 1 and forms a seat half for a guide ball 27. From the ball 27 extends an inner arm which engages the guide 24 and an outer arm 29 which is connected to the control arm 30.
25 Sædet for styrekuglen bliver ftildstændiggjort ved hjælp af en øvre lejehalvdel 31, som er anbragt i armaturhusets kappe 8, som udøver en trykkraft ved hjælp af en tætning 32, som er tætnet mod den nedre lejehalvdel 26 og styrekuglen 27.The seat of the guide ball is filled by means of an upper bearing half 31 which is arranged in the casing 8 of the luminaire which exerts a compressive force by means of a seal 32 which is sealed against the lower bearing half 26 and the guide ball 27.

Tovejs-betjeningsamien 30 tillader flytningen afføringen 24, som bevæger den bevægelige styreskive 23 translatorisk og roterende, hvilket valgfrit åbner hulrummene 18 og 20 af den faste styreskive 16 i forskellige andele, hvorved gennemgangen af forskellige mængder og andele af varmt og koldt vand bliver muliggjort, hvilket så bliver blandet 5 og løber ud fra armaturet. På denne måde bliver styringen af gennemstrømningen af blandet vand og blandingsandelene mellem varmt og koldt vand opnået.The bi-directional operating cam 30 allows the movement of the stool 24 which moves the movable guide disk 23 translationally and rotationally, which optionally opens the cavities 18 and 20 of the fixed guide disk 16 in various proportions, thereby permitting the passage of different amounts and proportions of hot and cold water. which then mixes 5 and runs out of the fixture. In this way, the control of the flow of mixed water and the mixing proportions between hot and cold water are achieved.
Den beskrevne og viste konstruktion af armaturet og indsatsen er kun et anvendelseseksempel ifølge opfindelsen.The described and shown construction of the luminaire and the insert is only an example of use according to the invention.
Ifølge opfindelsen er modboringeme 14 og 15 anbragt i indsatshusets 9 bunddel 10, hvil-10 ket stemmer overens med gennemst rømni ngskanaleme 11 og l2for varmt og koldt vand, når indsatsen er indsat i kammeret i 2 via armaturliusets 1 tilstrømningskanaler 4 og 5.According to the invention, the counter bores 14 and 15 are arranged in the bottom part 10 of the insert housing 9, which corresponds to the through-flow channels 11 and 12 for hot and cold water when the insert is inserted into the chamber in 2 via the inflow channels 4 and 5 of the luminaire 1.
I modboringeme 14 og 15 er hver indført en elementdel 33 sammen med en skruetrykfjeder 36 af metal. Elementdelen 33 er fremstillet af et elastomert materiale og har en rørformet form, som ved den nederste ende er forsnævret dannende en skulder 34.In the counter bores 14 and 15, each element member 33 is inserted together with a screw compression spring 36 of metal. The element member 33 is made of an elastomeric material and has a tubular shape which is narrowed at the lower end forming a shoulder 34.
15 Fjederen 36 er sammentrykket mellem elementdelens 33 skulder 34 og modboringemes 14 og 15 øvre grundflade og forspænder derfor elementdelen 33 mod bundfladen 3. Modboringeme 14 og 15, fjederen 36 og dementdelen 33 er således dimensioneret, at den nedre skulder 34 af elementdelen 33 rager ud fra indsatsens bunddel 10 i hviletilstanden. Som det er vist i figur 2 har elementdelen 33 et ringfremspring 35, som ikke kan 20 ses i sin i figur 1 viste indbygningstilstand, da den er sammentrykket mod modboringens 14, 15 væg. Ringfremspringet 35 ligger gnidende mod modboringemes 14 og 15 vægge og frembringer dermed en tætning.The spring 36 is compressed between the shoulder 34 of the element member 33 and the upper base surface of the counter bore 14 and 15 and therefore bias the element member 33 towards the bottom surface 3. The counter bores 14 and 15, the spring 36 and the dement member 33 are dimensioned so that the lower shoulder 34 of the element member 33 protrudes. from the bottom portion 10 of the insert in the idle state. As shown in Figure 2, the element member 33 has an annular projection 35 which cannot be seen in its installation state shown in Figure 1, since it is compressed against the wall of the counterbore 14, 15. The annular projection 35 lies rubbing against the walls of the counterbores 14 and 15, thus providing a seal.
Når indsatsen 19 - 26 er indført i armaturhusets 1 hulrum 2, ligger elementdelens 33 nedre skulderende 34 under tætning an mod hulrummets 2 bundflade 3, flugter over 25 tilførselskanaleme 4 og 5 og forspændt ved hjælp af fjedrene 36. På denne måde er husets 1 tilførselskanal 4 strømningsmæssigt tilsluttet til gennemstrømningskanalen 11 af indsatsens hunddel 10, og tilstrømningskanalen 5 for huset 1 er strømningsmæssigt 6 DK 173504 B1 tilsluttet til gennemstrømningskanalen 12 for indsatsens bunddel 10, hvorved de tætnende elementdele 33 forhindrer lækage til siden fra kanalerne 4, 5 og 10, 11. Samtidigt forspænder Rederens 36 kraft i tilslutning til det i bunden af modboringeme 14 og 15 virkende hydrauliske tryk hele indsatsen mod kappen 8 under opretholdelse af trykkraft 5 mod dens komponenter, inklusive den faste styreskive 16 og den bevægelige styreskive 23.When the insert 19 - 26 is inserted into the cavity 2 of the fixture housing 1, the lower shoulder 34 of the element member 33 seals under seal against the bottom surface 3 of the cavity 2, flushes over the supply ducts 4 and 5 and is biased by the springs 36. In this way, the supply duct of the housing 1 is 4 is connected in flow to the flow passage 11 of the insert dog part 10, and the flow channel 5 of the housing 1 is connected in flow 6 DK 173504 B1 to the flow passage 12 of the bottom part 10 of the insert, whereby the sealing element parts 33 prevent side leakage from the channels 4, 5 and 10, 11 At the same time, the power of the shipowner 36, in conjunction with the hydraulic pressure acting at the bottom of the counter bores 14 and 15, biases the entire insert against the sheath 8 while maintaining compressive force 5 against its components, including the fixed guide disc 16 and the movable guide disc 23.
Det er ikke nødvendigt, at fjederen 36 udøver en stor kraft, men at den ganske enkelt skal sikre en tildelt trykkraft til den tætnende elementdel 33 i fravær af vandtryk mod hulrummets 2 bundflade 3. Når vandtryk bliver tilført, virker dette delvis på de tætnende 10 elementdele 33 og det præcis på en flade, som er lig med forskellen mellem elementdelens 33 maksimale tværsnitsflade og den ved hjælp af skulderen 34 begrænsede åbningsflade. Den deraf fremkommende kraft bliver tilføjet til fjederens forspændende kraft på en sådan måde, at trykkraften mod hulrummets 2 bundflade 3 vokser svarende til vandtryksforøgelsen, hvorved der til enhver tid foreligger en passende resulterende samlet 15 kraft.It is not necessary for the spring 36 to exert a large force, but to simply provide an assigned compressive force to the sealing element portion 33 in the absence of water pressure against the bottom surface of the cavity 2, when water pressure is applied, this partially acts on the sealing 10. element portions 33 and it precisely on a surface equal to the difference between the maximum cross-sectional surface of element member 33 and the aperture surface restricted by the shoulder 34. The resulting force is added to the biasing force of the spring in such a way that the compressive force against the bottom surface 3 of the cavity 2 grows corresponding to the increase in water pressure, whereby there is at all times a suitable resulting total force.
Til tætningen kræver bundfladen 3 for armaturhusets 1 kammer 2 ikke mere end en enkelt slibeproces. Modboringeme 14 og 15 er lette at danne og er straks tilgængelige, når indsatsen ikke er indført i armaturets hulrum. Sammenbygningen og adskillelsen af de tætnende elementdele 33 og fjedrene 36 i modboringeme 14 og 15 af indsatsens 20 bunddel 10 er meget enkel, når indsatsen er fjernet fra armaturhuset 1. Desuden kan elementdelenes 33 tætningsskuldre 34 afprøves, når indsatsen er fjernet fra hulrummet 2 og kan ganske enkelt erstattes ved behov i modboringeme 14 og 15.For the seal, the bottom surface 3 of the chamber 2 of the luminaire housing 1 requires no more than a single grinding process. The counter bores 14 and 15 are easy to form and are immediately available when the insert is not inserted into the cavity of the fixture. The assembly and separation of the sealing element parts 33 and the springs 36 in the counter bores 14 and 15 of the bottom portion 10 of the insert 20 is very simple when the insert is removed from the housing 1. Furthermore, the sealing shoulders 34 of the element parts 33 can be tested when the insert is removed from the cavity 2 and can be tested. simply replaced when needed in the counter bores 14 and 15.
Figur 4 viser en tætnende elementdel 37, som er udformet til undgåelse af den i figur 1 viste med elementdelen 33 forbundne fjeder 36. Elementdelen 37 er fremstillet af 25 elastisk materiale og strækker sig til enden af den tilsvarende i indsatsens bunddel 10 anbragte modboring. Den har en tilstrækkelig elasticitet til at frembringe forspændingskraften, som er nødvendig til frontaltrykket mod bundfladen 3 af det i indsatsen inde- 7 DK 173504 B1 holdte hulrum 2. Den elastiske elementdel 37 strækker sig til enden af modboringen i indsatsens bunddel 10 og bevirker, når den er sammentrykket, en tætning ikke blot frontalt mod modboringens ende, men også mod selve de cylindriske vægge.Figure 4 shows a sealing element member 37 which is designed to avoid the spring 36 shown in Figure 1 with spring element 36. The element member 37 is made of 25 elastic material and extends to the end of the corresponding bore positioned in the bottom part 10 of the insert. It has sufficient elasticity to produce the biasing force required for the frontal pressure against the bottom surface 3 of the cavity contained in the insert 2. The elastic member portion 37 extends to the end of the counterbore in the bottom portion 10 of the insert and acts when it is compressed, a seal not only frontal to the end of the counterbore, but also to the cylindrical walls themselves.
Figur 4 viser, hvorledes det er muligt at lade den tætnende elementdel 37 trænge ind i 5 en i bundfladen 3 tilvejebragt modboring for at forhindre indsatsens drejning. Modboringen i bunddelen 3 tilføjer ingen væsentlige udgifter, fordi modboringen i bundfladen 3 til optagelse af elementdelen 37 på ingen måde kræver præcision ved dimensioneringen af dens diameter eller dens periferivægge, men kun skal være slebet ved dens endebundflade. Når stivheden af elementdelens 37 elastiske materiale ikke er tilstrækkelig til at 10 sikre indsatsen mod drejning, er det muligt at danne et fremspring af indsatsen udgående fra kraven, som omgiver elementdelen 37, hvilken krave delvis er at optage (ikke vist) i bundfladens 3 mod boring.Figure 4 shows how it is possible to allow the sealing element member 37 to penetrate into a counter bore provided in the bottom surface 3 to prevent the insertion of the insert. The counterbore in the bottom portion 3 adds no significant expense because the counterbore in the bottom surface 3 for receiving the element portion 37 in no way requires precision in the dimensioning of its diameter or its peripheral walls, but must be sanded only at its end bottom surface. When the stiffness of the elastic material of element member 37 is not sufficient to secure the insert against rotation, it is possible to form a projection of the insert from the collar surrounding the element member 37, which collar is partially accommodated (not shown) in the bottom surface 3 towards drilling.
I figur 5 virker elektriske elementdele 38 i princippet ligesom dem i figur 4, med det yderligere træk, at deres vægge er krummet indad mod deres inderside. Hydrauliske 15 tryk, som dannes i elementdelens 38 indre rum, bøjer de indre dele ved deres vægge radialt og frembringer en kraft, som har tendens til at forøge deres afstand fra indsatsens bunddel 10 til bundfladen 3 af armaturhusets 1 hulrum 2. På denne måde bliver den elastiske kraft med fordel forøget for at forøge frontaltrykket mellem delene 37, bunddelen 10 og husets 1 bundflade 3.In Figure 5, electrical element parts 38 are in principle similar to those in Figure 4, with the additional feature that their walls are curved inward toward their inside. Hydraulic pressures formed in the interior space of the element member 38 radially bend the inner parts at their walls and produce a force which tends to increase their distance from the bottom portion 10 of the insert to the bottom surface 3 of the cavity 2 of the fixture housing 1. advantageously, the elastic force is increased to increase the frontal pressure between the parts 37, the bottom part 10 and the bottom surface 3 of the housing 1.
20 Figur 6 viser, hvorledes de fjederelastiske elementdele 33 i figur 1 kan erstattes ved hjælp af rørformede elementdele 43 af i det væsentlige stift materiale, som er forsynet med O-ring tætninger, som er fremstillet af eftergiveligt elastomert materiale. En O-ring 44 er frontalt anbragt for at overføre forspændingen på bundfladen 3 af kammeret 2, som indeholder indsatsen, og en O-ring 45 er anbragt periferielt for at frembringe en 25 tætning i forhold til modboringemes 14 eller 15 cylindriske vægge. Forspændingskraften til belastning af elementdelen 43 bliver frembragt af skruetrykfjedre af metal, ligesom figur 1.Figure 6 shows how the spring elastic member parts 33 of Figure 1 can be replaced by tubular member parts 43 of substantially rigid material provided with O-ring seals made of resilient elastomeric material. An O-ring 44 is provided frontly to transmit the bias to the bottom surface 3 of the chamber 2 containing the insert, and an O-ring 45 is arranged circumferentially to provide a seal relative to the cylindrical walls of the counterbore 14 or 15. The biasing force for loading element member 43 is generated by metal screw springs, as is Figure 1.

Tilfælde, som de her beskrevne, i hvilke de rørformede tætningsdele er fremstillet af i det væsentlige stive materialer, er særligt anvendelige til at forhindre indsatsens drejning som følge af indtrængningen i modboringen i kammerets 2 bundflade 3, som er vist i figur 4.Cases such as those described herein in which the tubular sealing members are made of substantially rigid materials are particularly useful for preventing the insert's rotation due to the penetration of the counter bore of the bottom surface 3 of the chamber 2 shown in Figure 4.
5 Skruetrykfjedrene 36 af metal ifølge figur 6 kan erstattes af en hylster 46 af et eftergive-ligt, elastomert materiale, som er analog med elementdelen 36 i figur 4 med hensyn til dets elasticitet. Hylstret 46 kan være forsynet med indad krummet væg, som er vist i figur 7, og det hydrauliske tryk, som virker på hylstrets 46 inderside, bøjer den indad krummede væg radialt udad, hvorved der bliver frembragt en kraft, som har tendens til 10 at forspænde indsatsens bunddel 10 bort fra bundfladen 3. På denne måde bliver hylstrets 46 elastiske kraft med fordel forøget for at forspænde indsatsen og tilvejebringe en passende tætning.The metal screw springs 36 of FIG. 6 can be replaced by a sleeve 46 of a resilient elastomeric material analogous to the element portion 36 of FIG. 4 for its elasticity. The casing 46 may be provided with the inwardly curved wall shown in Figure 7, and the hydraulic pressure acting on the inside of the casing 46 bends the inwardly curved wall radially outwardly, thereby producing a force which tends to biasing the bottom portion 10 of the insert away from the bottom surface 3. In this way, the resilient force of the casing 46 is advantageously increased to bias the insert and provide a suitable seal.
Når kun to gennemstrømningskanaler for indføringen af varmt og koldt vand i de viste udførelsesformer er anbragt inden for indsatsens bunddel 10 og armaturhusets bundflade 15 3, mens det blandede vand strømmer ud, uden at vende tilbage til bunddelen og bundfla den 3 er opfindelsen dog på samme måde anvendelig i det tilfælde, i hvilket der inden for bunddelen også findes en eller flere tilbageføringskanaler til udgangen af det blandede vand. Desuden kan de i indsatsens bunddel dannede modboringer strække sig til den faste styreskive, og de rørformede, ljederelastiske elementdele kan så direkte virke på 20 den faste styreskives nederste flade, hvorved nødvendigheden af en tætning mellem den faste styreskive og indsatsens bunddel er undgået.However, when only two flow channels for introducing hot and cold water in the illustrated embodiments are disposed within the bottom portion 10 of the insert and the bottom surface of the luminaire 15 3, while the mixed water flows out, without returning to the bottom portion and bottom surface 3, the invention is the same. method useful in the case in which, within the bottom portion, one or more return channels are also provided for the output of the mixed water. In addition, the counterbores formed in the bottom portion of the insert may extend to the fixed guide disc and the tubular, leather-elastic member portions may then act directly on the bottom surface of the fixed guide disc, thereby avoiding the need for a seal between the fixed guide disc and the bottom portion of the insert.
