Den foreliggende opfindelse angår et etgrebsblandingsbatte-ri, især til sanitetsområdet og af den i krav l's indledning angivne art.The present invention relates to a single-lever mixing battery, in particular to the sanitary field and of the kind specified in the preamble of claim 1.

Et sådant blandingsbatteri kendes fra DE-A 37 475. Der er her tale om et blandingsbatteri for normaltryk, ved hvilket koldt og varmt vand strømmer ind gennem hver sin kanal i den faste skive og blandes i vendekanalen, hvorefter det blandede vand strømmer ud gennem en tredje kahal i den faste skive. I den kendte blander er de støjdæmpende finner helt, . begrænset til området omkring inds*trømningsåbningerne for koldt og varmt vand i vendekanalen. På denne måde opnår man ganske vist en god støjdæmpning ved lille gennem-*·* strømningsvolumen og højere tryk, men ved højere gennem strømningsvolumener bliver støjdæmpningen utilstrækkelig.Such a mixer is known from DE-A 37 475. This is a mixer for normal pressure, in which cold and hot water flow in through each channel in the fixed disk and mix in the reversing channel, after which the mixed water flows out through a third kahal in the fixed disk. In the known mixer, the noise-reducing fins are completely,. limited to the area around the inflow openings for cold and hot water in the reversing channel. In this way, it is true that a good noise attenuation is obtained at small flow volumes and higher pressures, but at higher through flow volumes the noise attenuation becomes insufficient.
Frem for alt er den kendte støjdæmpende anordning helt begrænset til brug ved højere tryk. Ved lavere tryk må man anvende på anden måde udførte støjdæmpende anordninger, 20 hvilket gør, at man må skelne mellem de to trykområder ved fremstilling og lagerholdelse, hvilket naturligvis øger omkostningerne.Above all, the known noise reduction device is completely limited for use at higher pressures. At lower pressures, noise-reducing devices designed in a different way must be used, which means that a distinction must be made between the two pressure ranges during manufacture and storage, which of course increases the cost.
Et eksempel på en støjdæmpende anordning alene for lavere 25 tryk er beskrevet i DE-OS 30 12 547. Ved denne er der i vendekanalen anbragt en opdæmningsplade umiddelbart foran ventilgennemgangen. Ved højere tryk er ikke blot støjdæmpningen utilfredsstillende - den drøvling, som opdæmnings- pladen medfører, er også utilladelig stor.An example of a noise-reducing device only for lower pressures is described in DE-OS 30 12 547. In this case, a damming plate is arranged in the reversing channel immediately in front of the valve passage. At higher pressures, not only is the noise attenuation unsatisfactory - the turbidity caused by the attenuation plate is also impermissibly large.

Formålet med den foreliggende opfindelse er at anvise et etgrebsbatteri af den omhandlede art, hvor den støjdæmpende anordning, som tidligere, består af stive, i ét med medbringeren udførte elementer, men har god støjdæmpning også 35 ved større gennemløbsvolumener og højere tryk og gør det muligt at anvende blandingsbatteriet ved både lavere og højere tryk.The object of the present invention is to provide a single-lever battery of the type in question, in which the noise-reducing device, as before, consists of rigid elements in one element made with the carrier, but has good noise reduction even at larger flow volumes and higher pressures and makes it possible to use the mixer at both lower and higher pressures.

Dette opnås ifølge opfindelsen ved den i krav 1 anviste udformning.This is achieved according to the invention by the design indicated in claim 1.
For at man skal kunne forstå den støjdæmpende virkning ved 5 den støjdæmpende anordning ifølge opfindelsen er det vig tigt at have en klar opfattelse af forskellen mellem- blandingsbatteriets støjegenskaber ved højere og lavere tryk.In order to be able to understand the noise-reducing effect of the noise-reducing device according to the invention, it is important to have a clear idea of the difference between the noise properties of the mixer mixer at higher and lower pressures.
Ved blandingsbatterier for højere tryk får man ved progres-siv åbning af blandingsventilen fra lukkestillingen først en støjtop ved meget smal åbning. Ved fortsat åbning af ventilen mindskes støjen igen, indtil dfen voksende vandstrøm gennem ventilen atter øger støjniveauet.In the case of mixer taps for higher pressures, the progressive opening of the mixing valve from the closed position only results in a noise peak with a very narrow opening. By continuing to open the valve, the noise is reduced again until the increasing flow of water through the valve again increases the noise level.
15 Ved blandere for lavt tryk adskiller støjudviklingen sig ved, at der ved ringe åbning i almindelighed ikke optræder t nogen støjtop. Tværtimod kan man iagttage, at støjudviklingen øges gradvis med øgende åbning af ventilen, hele tiden i afhængighed af blandingsbatteriets strømningsmod-20 stand.In the case of low-pressure mixers, the noise development differs in that at low openings no noise peaks generally occur. On the contrary, it can be observed that the noise development increases gradually with increasing opening of the valve, all the time depending on the flow resistance of the mixer.
Blandingsbatteriet ifølge opfindelsen klarer begge typer af støjkurver. Ved højere tryk undertrykker de parallelle, i vendekanalen indskydende finner støjtoppen, medens den ud 25 for den tredje gennemløbskanal, i dette tilfælde udløbet for det blandede vand, beliggende opdæmningsplade modvirker den monotone forøgelse af støjudviklingen ved vekslende vandstrøm. Ved lavere tryk, når vandstrømmene går i modsat retning gennem ventilen, sikrer finnerne i vendekanalen ved 30 smal åbning en lille drøvling, som medfører en vel tilpasset støjdæmpning.The mixer according to the invention handles both types of noise curves. At higher pressures, the parallel fins pushing into the reversing channel suppress the noise peak, while the dam plate located outside the third passage channel, in this case the outlet of the mixed water, counteracts the monotonic increase of the noise development by alternating water flow. At lower pressures, when the water flows go in the opposite direction through the valve, the fins in the reversing channel at 30 narrow openings ensure a small throttle, which results in a well-adapted noise reduction.
Opdæmningspladen ligger under denne åbningsfase i det væsentlige uden for vandets strømningsvej og har kun lidt 35 indflydelse på støjdæmpningen. Hvis ventilen imidlertid åbnes mere, vil opdæmningspladen i voksende grad blive berørt af vandstrømmen og øger derved strømningsmodstanden, - 3 -During this opening phase, the dam plate is substantially outside the water flow path and has only a small influence on the noise attenuation. However, if the valve is opened more, the dam plate will be increasingly affected by the water flow, thereby increasing the flow resistance, - 3 -
DK 164301 BDK 164301 B
hvorigennem også støjdæmpningen vokser i nøje forhold til den forøgelse af støjudviklingen, som skulle opnås uden støjdæmpning. Hverken ved højere eller lavere tryk får man nogen unødig drøvling af vandstrømmen i nogen del af åb-ningsfasen.through which the noise attenuation also grows in close proportion to the increase in the noise development which was to be achieved without noise attenuation. Neither at higher nor lower pressures is there any unnecessary throttling of the water flow in any part of the opening phase.
Ved at man kun udnytter i ét med medbringeren udførte, massive elementer i den støjdæmpende kombination, kommer der ingen yderligere monteringsomkostninger til, i modsætning til, hvad der er tilfældet ved de til støjdæmpning tidligere anvendte sier. De støjdæmpende elementer udgøres af relativt grove, glatte strukturer, som har meget lidt tendens til at blive tilstoppede eller fange snavs. Også de på optimal måde udformede passager sørger for, at venti-^ lens og den støjdæmpende anordnings funktion opretholdes over adskillige år.By using only solid elements in the noise-reducing combination made with the carrier in one go, there are no additional installation costs, in contrast to what is the case with the previously used noise reduction sayers. The noise-reducing elements consist of relatively coarse, smooth structures, which have very little tendency to become clogged or catch dirt. The optimally designed passages also ensure that the function of the valve and the noise reduction device is maintained over several years.
Afstanden mellem opdæmningspladens frie ende og kontaktfladen mellem den faste skive og regulerskiven er hensigtsmæs-20 sigt større end afstanden mellem finnernes frie ender og kontaktplanet mellem den faste skive og reguleringsskiven. Generelt kan man ved hjælp af den højde, med hvilken opdæ'm-ningspladen strækker sig i vendekanalen, tilpasse pladens andel af den totale støjdæmpning i den støjdæmpende kom-25 bination til de herskende forhold. Hvad angår de støjdæmpende finner er det derimod hensigtsmæssigt at føre deres nedre ender så langt ud som muligt mod kontaktfladen mellem den faste og den bevægelige reguleringsskive.The distance between the free end of the dam plate and the contact surface between the fixed disc and the adjusting disc is suitably greater than the distance between the free ends of the fins and the contact plane between the fixed disc and the adjusting disc. In general, by means of the height at which the dam plate extends in the turning channel, the share of the plate of the total noise attenuation in the noise attenuation combination can be adapted to the prevailing conditions. In the case of the noise-reducing fins, on the other hand, it is expedient to guide their lower ends as far as possible towards the contact surface between the fixed and the movable adjusting disc.

Opdæmningspladens frie ende bør være afrundet på den side, som vender mod vendekanalens centrum. På den måde lettes vandets forbistrømning ved både lavere og højere tryk ved, at støjfremkaldende hvirvler undertrykkes.The free end of the dam plate should be rounded on the side facing the center of the turning channel. In this way, the bypass flow of the water at both lower and higher pressures is facilitated by suppressing noise-causing vortices.

Opbygningen af et blandingsbatteri af den art, som er af interesse i det foreliggende tilfælde, beskrives bedst i forbindelse med fig. 2. En første keramikskive 1 er stationær eller i det mindske ikke drejelig og ikke forskydeligt anordnet i et ikke vist batterihus. Denne med punkteret ^ streg viste første skive 1 benævnes i det følgende den faste skive. Den er forsynet med to om en symmetrilinie symmetrisk beliggende gennemløbskanaler 2 samt en på denne symmetrilinie beliggende gennemløbskanal 3. Den i fig. 1 opadrettede flade er poleret til høj overfladenøjagtighed og samvirker på kendt måde med en på tilsvarende måde bearbejdet anden keramikskive 4. Denne anden keramikskive 4 kan dels drejes om en vinkelret på kontaktfladen stående akse og dels forskydes lineært i forhold til den faste skive. Da den på denne måde indstiller strømmen og temperatu- 2 0 ren hos det angivne, blandede vand, benævnes den herefter reguleringsskiven.The construction of a mixer of the kind of interest in the present case is best described in connection with FIG. A first ceramic disc 1 is stationary or at least not rotatable and not slidably arranged in a battery housing (not shown). This first disc 1 shown in dotted line is hereinafter referred to as the fixed disc. It is provided with two passage channels 2 symmetrically located about a line of symmetry and a passage channel 3 located on this line of symmetry. 1 upward surface is polished to high surface accuracy and cooperates in a known manner with a similarly machined second ceramic disc 4. This second ceramic disc 4 can partly be rotated about an axis perpendicular to the contact surface and partly displaced linearly relative to the fixed disc. Since it adjusts the flow and temperature of the specified mixed water in this way, it is hereinafter referred to as the control dial.

En medbringer 6, som fortrinsvis er fremstillet af plast, er med en O-ring 7 som pakning påsat reguleringsskiven 4.A carrier 6, which is preferably made of plastic, is fitted with an O-ring 7 as a gasket on the adjusting disc 4.
3^ Medbringeren 6 er forbundet med reguleringsskiven 4 på en sådan måde, at alle bevægelser hos medbringeren 6 overføres til reguleringsskiven 4. Medbringerens 6 bagside 8 er forsynet med en udskæring 9, i hvilken en ikke vist, med et håndtag forbundet ventilspindel gør indgreb. På sin mod 33 reguleringsskiven 4 vendte side er medbringeren 6 forsynet med en udskæring 10, som i retning opad forlænger og lukker reguleringsskivens 4 gennemløbskanal 5. Medbringerens 6 - 5 -The carrier 6 is connected to the adjusting disc 4 in such a way that all movements of the carrier 6 are transmitted to the adjusting disc 4. The rear side 8 of the carrier 6 is provided with a cut-out 9, in which a valve stem (not shown) connected to a handle engages. On its side facing the control disc 4, the carrier 6 is provided with a cut-out 10, which in the upward direction extends and closes the passage channel 5 of the control disc 4. The carrier 6 - 5 -

udtagning 10 danner derved i kombination med reguleringsskivens 4 gennemløbskanal 5 en vendekanal 15, gennem hvilken vandet kan strømme fra gennemløbskanalerne 2 i den faste skive 1 til gennemløbskanalen 3 eller omvendt.outlet 10 thereby forms in combination with the passage channel 5 of the regulating disc 4 a reversing channel 15, through which the water can flow from the passage channels 2 in the fixed disc 1 to the passage channel 3 or vice versa.

Den side af medbringerens 6 udtagning 10, som ligger nærmest den faste skives 1 gennemløbskanaler 2, er i ét med medbringeren udført med et flertal smalle finner 11. Disse finner stikker ud nedad fra medbringeren 6 og ind i regule-ringsskivens 4 gennemløbskanal 5, hvor de kan ligge an mod kanalvæggen. Finnernes 11 radielle højde er sammenlignelig med e-iler noget mindre end størrelsen af gennemløbskanalerne 2 i den faste skive 1. Finnernes 11 frie nedre ender er afrundet på den side, som vender mod vendekanalens 15 cen-^ trum. Finnerne når omtrent frem til kontaktplanet mellem den faste skive 1 og reguleringsskiven 4.The side of the recess 10 of the carrier 6, which is closest to the passage channels 2 of the fixed disc 1, is in one with the carrier made with a plurality of narrow fins 11. These fins protrude downwards from the carrier 6 and into the passage channel 5 of the adjusting disc 4, where they can rest against the duct wall. The radial height of the fins 11 is comparable to e-iles somewhat smaller than the size of the passage channels 2 in the fixed disc 1. The free lower ends of the fins 11 are rounded on the side facing the center of the turning channel 15. The fins approximately reach the contact plane between the fixed disc 1 and the adjusting disc 4.
I den højre del af tegningen skyder en i ét med medbringeren udført, massiv opdæmningsplade 12 ud fra bunden af med- on bringerens 6 udtagning 10. Også opdæmningspladen rager ind i reguleringsskivens 4 gennemløbskanal 5, men ligger på større afstand fra kontaktplanet mellem den faste skive 1 og reguleringsskiven 4 end finnerne 11. Også opdæmnings-pladens 12 nedre ende er afrundet på den side, som vender 25 mod centrum af den af reguleringsskiven 4 og medbringeren 6 afgrænsede vendekanal.In the right-hand part of the drawing, a solid dam plate 12 made in conjunction with the carrier projects from the bottom of the outlet 10 of the carrier 6. The dam plate also projects into the passage channel 5 of the adjusting disc 4, but is at a greater distance from the contact plane between the fixed disc 1 and the adjusting disc 4 than the fins 11. The lower end of the dam plate 12 is also rounded on the side facing 25 towards the center of the turning channel delimited by the adjusting disc 4 and the carrier 6.
Den indbyrdes placering af opdæmningspladen 12 og gennemløbskanalen 3 i den faste skive 1 er væsentlig. Hvis gen-nemløbsåbningens 3 tværsnit med en vinkelret på den faste skives 1 symmetriakse stående, tænkt linie deles i to halve med ens overflade, skal ved lukket ventil opdæmningspladens 12 skarpe nedre hjørne 13 ligge lige over den halvdel af den faste skives 1 gennemløbskanal 3, som ligger længst fra 35 gennemløbskanalerne 2. De i ét med medbringeren støbte finner 11 og opdæmningspladen 12 danner en støjdæmpende anordning, som virker både ved lavt og højt tryk.The mutual placement of the dam plate 12 and the passage channel 3 in the fixed disc 1 is essential. If the cross-section of the passage opening 3 with a perpendicular axis perpendicular to the axis of symmetry of the fixed disk 1 is divided into two halves with an equal surface, the closed lower corner 13 of the dam plate 12 must lie just above half of the passage channel 3 of the fixed disk 1. which is furthest from the passage channels 2. The fins 11 molded in conjunction with the carrier and the dam plate 12 form a noise-reducing device which acts at both low and high pressure.

Ved .den driftsform, hvor højt tryk forekommer, strømmer varmt og koldt vand ind gennem den faste skives 1 gennemløbskanaler 2, blandes i vendekanalen 15 og strømmer som blandet vand ud gennem den faste skives 1 gennemløbskanal 5 3.In the mode of operation where high pressure occurs, hot and cold water flows in through the passage channels 2 of the solid disk 1, mixes in the reversing channel 15 and flows out as mixed water through the passage channel 5 3 of the solid disk 1.
Når ventilen kun er noget åben, rammer de i vendekanalen 15 indstrømmende vandstrømme først finnernes 11 nedre ender og dæmpes og gøres mere laminare af disse finner, hvilket næ-sten helt eliminerer de i denne første åbningsfase optrædende støjtoppe. Finnernes 11 stillingsafhængige støjdæmpning, understøttes i denne åbningsfase af en svag, uspecifik virkning fra opdæmningspladen 12.When the valve is only slightly open, the water currents flowing into the reversing channel 15 first hit the lower ends of the fins 11 and are dampened and made more laminar by these fins, which almost completely eliminates the noise peaks occurring in this first opening phase. The position-dependent noise attenuation of the fins 11 is supported in this opening phase by a weak, non-specific effect from the attenuation plate 12.
15 Hvis blanderen åbnes mere, mindskes betydningen af finner nes 11 stillingsafhængige støjdæmpning, medens en voksende del af det vand, som strømmer ind i vendekanalen 15, går uden om finnerne 11. Denne stillingsafhængige støjdæmpning behøves dog ikke længere ved denne indbyrdes placering af 20 skiverne 1 og 4, da der nu ikke længere optræder nogen støjtoppe. I stedet modvirkes den gradvis øgende, uspecifikke støjudvikling ved voksende åbning af ventilen stedse mere af opdæmningspladen 12, som bevæger sig i retning mod den faste skives 1 gennemløbskanaler 2 og derved stadigt 25 kraftigere dæmper blandingsvandstrømmen.If the mixer is opened more, the significance of the position-dependent noise attenuation of the fins 11 decreases, while a growing part of the water flowing into the reversing channel 15 bypasses the fins 11. However, this position-dependent noise attenuation is no longer needed by this mutual placement of the 20 discs. 1 and 4, as no noise peaks now occur. Instead, the gradually increasing, non-specific noise development is counteracted by increasing opening of the valve more and more by the dam plate 12, which moves in the direction of the passage channels 2 of the solid disc 1 and thereby increasingly dampens the mixing water flow.
Den støjdæmpende virkning af finnerne 11 og opdæmningspladen 12 er altså optimalt tilpasset til den stillings- og strømningsafhængige støjkarakteristik ved denne driftsform.The noise-reducing effect of the fins 11 and the dam plate 12 is thus optimally adapted to the position- and flow-dependent noise characteristics of this mode of operation.

Ved drift med lavt tryk er vandets strømningsretning vendt. Koldt vand strømmer gennem den faste skives 1 gennemløbsåbning 2 ind i vendekanalen 15 og afgives fra denne i indstillelige, af de to skivers 1,3 indbyrdes stilling afhæn-55 gige portioner til den faste skives 1 to gennemløbskanaler 2. Den ene af disse kanaler 2 leder direkte til blandingsbatteriets udløb, medens den anden leder til en lavtryks-In low pressure operation, the water flow direction is reversed. Cold water flows through the passage opening 2 of the solid disk 1 into the reversing channel 15 and is discharged therefrom in adjustable portions depending on the mutual position of the two disks 1,3 to the two passage channels 2 of the solid disk 1. One of these channels 2 leads directly to the outlet of the mixer, while the other leads to a low-pressure

Ved blot noget åben lavtryksventil er opdæmningspladens indvirken på vandstrømningen meget lille. Finnerne 11 dæm-5 per kun ubetydeligt vandstrømmene til gennemløbskanalerne 2. Støjdæmpningen hos pladen 12 og finnerne 11 mod's varer da den i denne stilling ringe støjudvikling ved lavtryksventiler. Ved øgende åbning hos lavtryksventilen flyttes opdæmningspladen 12 stadigt mere ind i vandstrømmen. Den 10 derigennem øgende dæmpning modsvarer det ved lavtryksventiler iagttagne, med voksende åbning stigende behov for støjdæmpning.With just one open low pressure valve, the impact of the dam plate on the water flow is very small. The fins 11 dampen only the water flows to the passage channels 2 only insignificantly. The noise attenuation of the plate 12 and the fins 11 mod's lasts as in this position little noise development at low pressure valves. With increasing opening of the low pressure valve, the dam plate 12 moves more and more into the water flow. The 10 thereby increasing attenuation corresponds to the increasing need for attenuation observed at low pressure valves, with increasing opening.
