Description
i DK 176163 B1in DK 176163 B1
Den foreliggende opfindelse angår en friskluftventil af den art der omfatter et hus for indbygning i en spalteformet åbning i vægge eller rammer, eksempelvis en vindusramme, og omfattende et aflangt ventilationsspjæld, hvis ender er forbundet med, ved husets ender lejrede, trykudløselige snapkoblinger, der er aktiverbare 5 imellem en åben og en lukket stilling for ventilationsspjældet.The present invention relates to a fresh air valve of the kind comprising a housing for incorporation into a slit-shaped opening in walls or frames, for example a window frame, and comprising an elongated ventilation damper, the ends of which are connected to pressure-releasable snap couplings at the ends of the housing, which are activatable 5 between an open and a closed position for the ventilation damper.
Eksempler på sådanne friskluftventiler kendes fra WO 90/10777, dvs. en ventil med en aflang spjældplade, som ved begge ender er forbundet med modstående sider af en flad kanalbøsning ved hjælp af respektive trykbetjenelige 10 snapkoblinger på en sådan måde, at spjældpladen fra en åben stilling i afstand foran mundingen af kanalbøsningen kan indtrykkes til en selvholdende lukkestilling, hvorfra den er åbnelig ved fjederkraft efter en påfølgende kort, yderligere indtrykningspåvirkning. Ventilen kan fremtræde helt uden betjeningsorganer, og i og med at spjældpladen er i længdevippelig forbindelse 15 med snapkoblingerne er det uden betydning, om den skævvippes under ind- og udføringen.Examples of such fresh air valves are known from WO 90/10777, viz. a valve having an elongated damper plate, which is connected at opposite ends to opposite sides of a flat duct sleeve by means of respective pressurized 10 snap couplings in such a way that the damper plate from an open position at a distance in front of the mouth of the duct sleeve can be pressed into a self-holding closing position , from which it is open by spring force after a subsequent short, additional impact. The valve can appear completely without actuators, and since the damper plate is in longitudinally inclined connection with the snap couplings, it is irrelevant whether it is tilted during insertion and execution.
Det benyttede låseprincip er altså det samme, der i enkelt-udførelse kendes fra trykkuglepenne, dog med en noget kraftigere udførelse af snapkobllingerne.The locking principle used is thus the same that is known in the single version from the pressure ballpoint pens, but with a somewhat more powerful design of the snap couplings.
20 Der er benyttet et koblingssystem baseret på en metallisk fjederhage, som styres sideværts ved samvirke med en skrå kamflade på den ydre teleskopdel af koblingen. Denne indretning har imidlertid vist sig at udvise forskellige mindre heldige sider, såsom at fjederhagen er vanskelig eller dyr at fremstille med den fornødne grad af nøjagtighed, og at koblingerne i sig selv er omstændelige at 25 montere, og yderligere er koblingerne af en størrelse der medfører en relativ stor indbygnings dybde, og derfor fordrer fjernelse af relativt store materialemængder i den flade i hvilken friskluftventilen de monteres, hvilket med nutidens krav til effektivitet ikke er ønskeligt.A coupling system based on a metallic spring chuck is used which is laterally controlled by cooperation with an inclined cam surface on the outer telescopic portion of the coupling. However, this device has been found to exhibit various less fortunate sides, such as that the spring hanger is difficult or expensive to manufacture with the required degree of accuracy, and that the couplings themselves are cumbersome to mount, and furthermore the couplings are of a size which entails the depth of a relatively large installation, and therefore, the removal of relatively large quantities of material in the surface in which the fresh air valve is mounted, which is not desirable with today's requirements for efficiency.
30 Et andet låseprincip kendes fra GB 2352270, der omfatter en trykbetjent ind- og udskydningskobling, primært til brug i forbindelse med en lukning og åbning af en spjældplade i en ventilationsspalteventil. Koblingen er udført med et koblingslegeme, som mod en fjederkraft er indtrykkelig i en omgivende føringsdel og som er udført med en styreknast på føringsdelen kan udvirke sådanne 35 drejningsomstillinger af koblingssystemet, at dette midlertidigt kan fastholdes i en indtrykket stilling, hvorfra det er udløseligt ved en videregående, kort indtrykning, til en udskudt stilling. Det særlige ved opfindelsen er at der herved tilvejebringes en robust snaplåsevirkning ved at styreknasten er udført som en sprøjtestøbt 2 DK 176163 B1 detalje på et elastisk udbøjeligt vægafsnit af føringsdelen og samvirker med spordele med forskellige retninger, bunddybder og hældninger. Der indgår således i denne snaplås to fjedersystemer, dels en spiralfjeder, der tilsikrer ud- og indskydningen af koblingslegemet, og dels det forhold at føringsdelens vægge 5 omfatter opslidsninger, der kombineret med en elastisk udformning af føringsdelens vægge medfører væggene kan udtrykkes som en elastisk tungedel, der muliggør at styreknasten arreteres i den indtrykkede stilling, og endvidere at denne ved fornyet trykpåvirkning kan forskydes ud i sporet til den udskudte position. Denne udskydningskobling har den fordel i forhold til den i WO 90/10777 10 angivne kobling, at den er mere enkel i sin udførelse, ligesom den er betydeligt lettere at montere, med denne løser ikke problemet med den store indbygningsdybde for friskluftsventilen.Another locking principle is known from GB 2352270, which comprises a pressure-operated insertion and extension coupling, primarily for use in connection with closing and opening a damper plate in a ventilation slit valve. The coupling is provided with a clutch body which is resilient against a spring force in a surrounding guide part and which is provided with a control knob on the guide part can effect such rotational adjustments of the coupling system that it can be temporarily held in an depressive position from which it is releasable at a advanced, short impression, to a postponed position. The special feature of the invention is that this provides a robust snap-locking effect in that the control box is designed as an injection molded detail on an elastically flexible wall section of the guide member and interacts with track parts with different directions, bottom depths and slopes. Thus, in this snap-lock two spring systems are included, one a coil spring which secures the insertion and insertion of the coupling body, and the fact that the walls of the guide member 5 include slots which, combined with an elastic design of the guide part's walls, cause the walls to be expressed as an elastic tongue part. , which allows the control box to be arrested in the depressed position, and further that it can be displaced out of the groove to the deferred position by renewed pressure. This extension coupling has the advantage over the coupling specified in WO 90/10777 10 that it is simpler in its design and also considerably easier to assemble, but this does not solve the problem with the large installation depth of the fresh air valve.
De kendte friskluftventiler omfatter typisk en rundtgående tætningsliste af 15 skumgummi eller skumplast, der er pålimet den imod kanalbøsningen tilvendende side af ventilationsspjældet, langs dennes yderrand. Ved indtrykningen af udskydningskoblingen til ventilationsspjældets lukkede position, antrykkes tætningslisten imod en anlægsflade på den tilvendende side af kanalbøsningen, og endvidere sker der ved denne lukning af ventilationsspjældet, en 20 sammentrykning af isoleringsmaterialet, således at ventilationsspjældet er plant med kanalbøsningen. Ved åbning af ventilationsspjældet sker der en efterfølgende udvidelse af nævnte tætningsliste til udgangsvoluminet/tykkelsen. Nævnte udvidelse medfører en reduktion af spalteåbningen i den åbne friskluftventil, som nødvendiggør, for at opnå den fornødne ventilationsevne ved friskluftventilen, en 25 relativt stor forskydning af ventilationsspjældet i retning bort fra kanalbøsningens munding. Dette har været en årsag til, at man hidtil har måttet acceptere den relativt store indbygningsdybde ovennævnte trykbetjenelige snapkoblinger. En yderligere ulempe ved de nævnte kendte friskluftventiler er, at placeringen af tætningslisten langs yderranden af ventilationsspjældet medfører at de 30 trykbetjente ind- og udskydningskoblinger er placerede indenfor kanalbøsningens strømningsåbning, hvilket betyder at disse med tiden bliver tilsmudsede af støv m.m. der findes i den ventilationsluft der passerer igennem strømningsåbningen. Tilsmudsningen kan med tiden medføre at de trykbetjente ind- og udskydningskoblinger funktionalitet nedsættes. Placeringen af tætningslisten 35 tætningslisten langs yderranden af ventilationsspjældet medfører endvidere, at de dele af denne der er placeret på ydersiderne af de trykbetjente ind- og udskydningskoblinger, ved halv åbning af friskluftsventilen dvs. hvor kun den ene af de trykbetjente ind- og udskydningskoblinger udskydes, bliver klemt ekstra hårdt 3 DK 176163 B1 imod kanalbøsningens reces, som følge af vipning af ventilspjæld-pladen, hvilket medfører et øget deformation af nævnte tætningsliste.The known fresh air valves typically comprise a circumferential sealing strip of 15 foam rubber or foam plastic, which is glued to the side of the ventilation damper facing the duct sleeve, along its outer edge. By pressing the extension coupling to the closed position of the ventilation damper, the sealing strip is pressed against a contact surface on the opposite side of the duct sleeve, and furthermore, by this closing of the ventilation damper, a compression of the insulating material occurs so that the ventilation damper is level with the duct sleeve. When the ventilation damper is opened, the said sealing strip is subsequently expanded to the output volume / thickness. Said expansion results in a reduction of the gap opening in the open fresh air valve which, in order to obtain the required ventilation capacity at the fresh air valve, results in a relatively large displacement of the ventilation damper in the direction away from the mouth of the duct sleeve. This has been one of the reasons why so far the relatively large installation depth of the above-mentioned pressurized snap couplings has had to be accepted. A further disadvantage of the aforementioned known fresh air valves is that the location of the sealing strip along the outer edge of the ventilation damper causes the 30 pressure-operated insertion and extension couplings to be located within the flow opening of the duct sleeve, which means that over time they become soiled by dust etc. contained in the ventilation air passing through the flow opening. Over time, soiling can reduce the functionality of the push-in and release couplings. Furthermore, the location of the sealing strip 35 sealing strip along the outer edge of the ventilation damper causes the parts thereof to be located on the outside of the pressure-operated insertion and extension couplings, at half opening of the fresh air valve ie. where only one of the pressure-operated insertion and extension couplings is extended, extra hard is pressed against the recess of the duct sleeve due to the tilting of the valve damper plate, which results in increased deformation of said sealing strip.
Det er således formålet med opfindelsen at angive en friskluftventil, der 5 frembyder en mindre indbygningsdybde, end de kendte friskluftventiler, men som samtidigt frembyder samme fristrømningsareal for passerende luft igennem frsikluftventilen i dennes åbne position.It is thus the object of the invention to provide a fresh air valve which offers a smaller depth of installation than the known fresh air valves, but which simultaneously offers the same free flow area for passing air through the fresh air valve in its open position.
Et yderligere formål med opfindelsen er at tilvejebringe en friskluftventil, der 10 frembyder en mere effektiv beskyttelse af de trykbetjente ind- og udskydningskoblinger imod tilsmudsning, ligesom det også tilstræbes at angive en friskluftventil, hvor tætningslisten ikke belastes unødigt hårdt ved ensidig åbning af friskluftventilen.It is a further object of the invention to provide a fresh air valve which provides more effective protection of the pressurized push-in and push-out couplings against contamination, and also to provide a fresh air valve where the sealing strip is not unduly burdened by unilateral opening of the fresh air valve.
15 Det er ved opfindelsen indset, at det vil være muligt at løse ovennævnte problemstillinger ved en friskluftventil af den angivne art, som er kendetegnet ved, at de trykbetjente ind- og udskydningskoblinger er placerede i henholdsvis en første- og en anden koblingsbrønd der lokaliseret i hver ende af kanalbøsningen, at gennemstrømningsåbningen er placeret imellem nævnte koblingsbrønde, og at 20 tætningslisten udgøres af en læbering der er placeret i en rundtgående reces i kanalbøsningens gennemstrømningsåbning.It is recognized by the invention that it will be possible to solve the above-mentioned problems with a fresh air valve of the specified type, characterized in that the pressure-operated insertion and extension couplings are located in a first and a second coupling well located in at each end of the channel sleeve, that the flow opening is positioned between said coupling wells and that the sealing strip is constituted by a lip ring located in a circumferential recess in the flow opening of the channel sleeve.
Herved opnås det, som følge af lokaliseringen af tætningslisten i den rundtgående reces i kanalbøsningen, at åbningshøjden for ventilspjældet kan 2 5 reduceres, idet tætningslisten derved ikke optager plads i friskluftventilens åbningsareal. Dette medfører således mulighed for at reducere den vandring de trykbetjente ind- og udskydningskoblinger skal udføre imellem ventilspjældets åbne og lukkede position, og dermed mulighed for at reducere indbygningsdybden for friskluftventilen. Ved at de trykbetjente ind- og udskydningskoblinger er 3 0 placerede i særlige koblingsbrønde, der er adskilte fra kanalbøsningens strømningsåbning, opnås yderligere den fordel, at de trykbetjente ind- og udskydningskoblinger beskyttes bedre imod tilsmudsning.Hereby, due to the location of the sealing strip in the circumferential recess in the duct sleeve, it is achieved that the opening height of the valve damper can be reduced, as the sealing strip thus does not take up space in the opening area of the fresh air valve. This means that it is possible to reduce the travel the pressure-operated insertion and extension couplings must perform between the open and closed position of the valve damper, and thus the possibility of reducing the depth of installation of the fresh air valve. The fact that the pressure-operated insertion and extension couplings are located in special coupling wells that are separate from the flow opening of the duct sleeve further provides the advantage that the pressure-operated insertion and extension couplings are better protected against contamination.
I den hensigt at placere tætningslisten så tæt på ydersiden af ventilen som 35 muligt, kan læberingen med fordel være støbt sammen med kanalbøsningen ved to-komponent sprøjtestøbning.In order to position the sealing strip as close to the outside of the valve as possible, the lip ring may advantageously be molded together with the duct bushing by two-component injection molding.

Herved opnås den fordel at den nødvendige åbnehøjde bliver reduceret med højden af tætningslisten, idet tætningslisten er lokaliseret i recessen i kanalbøsningen. Desuden opnås ved to-komponentstøbningen den fordel, at man herved sparer den arbejdsgang der er forbundet med påklæbning/montering af 5 tætningslisten.Hereby, the advantage is obtained that the required open height is reduced by the height of the sealing strip, the sealing strip being located in the recess in the duct sleeve. In addition, the two-component casting gives the advantage of thereby saving the working process associated with adhesion / mounting of the sealing strip.
i I den hensigt at optimere produktionsprocessen ved fremstilling af friskluftventilen ifølge opfindelsen, kan ventilationsspjældet udgøres af et aflangt,i den rundtgående reces i kanalbøsningen optageligt, rørformet fladagtigt profil af 10 stift, eller delvis stift materiale, hvilket rørformede, fladagtige profil har en første hvælvet sideflade og en anden hvælvet sideflade, der i forening danner et hulrum for optagelse og indpresning af udragende tunger på endedele, der udgør en del af de trykudløselige snapkoblinger, og hvor bredden af den anden hvælvede sideflade er mindre end bredden af den første hvælvede sideflade, således at den 15 anden sideflade derved fremstår med paralleltforløbende sideflige for anlæg imod læberingen.In order to optimize the production process in the manufacture of the fresh air valve according to the invention, the ventilation damper may consist of an elongated, tubular flat-like profile of 10 pins, or partially rigid, tubular flat-shaped profile having a first vault side surface and a second vaulted side surface, which together form a cavity for receiving and pressing projecting tongues onto end portions forming part of the pressure-releasable snap couplings and wherein the width of the second vaulted side surface is less than the width of the first vaulted side surface; so that the second side face thereby appears with parallel extending side tabs for abutment against the lip ring.
Herved opnås det at det rørformede fladagtige profil kan længdeafpasses ved et vinkelret snit, hvilket forenkler fremstillingsproceduren betydeligt, i forhold til 20 et ventilspjæld, med afrundede endepartier, ligesom materialespild også modvirkes, eftersom afrundingerne vil medføre at der skal fjernes materiale der ikke kan genanvendes.Hereby it is obtained that the tubular flat-like profile can be length-adjusted by a perpendicular incision, which considerably simplifies the manufacturing procedure, relative to a valve damper, with rounded end portions, as well as material waste is also counteracted, since the rounding will result in the removal of non-recyclable material.
I en anden udførelses form af det rørformede fladagtige profil kan dette 25 omfatte en opslidsning i den anden hvælvede sideflade. Herved opnås en besparelse af materialet der medgår til fremstilling af ventilspjældet.In another embodiment of the tubular flat-like profile, this may comprise a slit in the second vaulted side surface. This results in a saving of the material used to make the valve damper.
Imidlertid er det yderligere ved opfindelsen indset, at den normale og ønskede afrunding af ventilspjældets ender kan bibeholdes ved at udforme 30 koblingsbrøndene og endedelene med en afrunding på den modstående side af den udragende tunge der optages i det rørformede fladagtige rørprofil.However, it is further recognized by the invention that the normal and desired rounding of the valve damper ends can be maintained by forming the coupling wells and end portions with a rounding on the opposite side of the protruding tongue accommodated in the tubular flat tubular profile.
I den hensigt at sikre en god tætning imellem koblingsbrøndene og spalteåbningen i kanalbøsningen, kan de imod spalteåbningen vendende sider af 35 koblingsbrøndene have et konkavt forløb, der tilnærmelsesvist er ligedannet med den anden hvælvede sideflade af det aflange, rørformede, fladagtige profil, og over hvilket konkavt forløb tætningslisten forløber.In order to ensure a good seal between the coupling wells and the gap opening in the duct sleeve, the sides of the coupling wells facing the gap opening may have a concave course approximately similar to the second vaulted side surface of the elongate, tubular, flat profile. concave course sealing strip extends.

Friskluftventilens kanalbøsning er typist fremstillet af sprøjtestøbt plast, og er en relativt tyndvægget konstruktion, der undertiden ved indpresning i en vindusramme eller -karm kan knække. I den hensigt at tilføre kanalbøsningen en tilstrækkelig stabilitet kan der i kanalbøsningens spalteåbning findes et antal 5 tværgående broer.The duct sleeve of the fresh air valve is typically made of injection-molded plastic, and is a relatively thin-walled construction that can sometimes break when pressed into a window frame or frame. In order to give the duct sleeve sufficient stability, a number of 5 transverse bridges can be found in the duct sleeve opening.
I de tilfælde hvor broernes udbredelse i kanalbøsningens forløb ønskes udbredt til maksimal bredde, kan de imod spjældet vendende endepartier af broerne være tildannede med en runding der svarer til den anden hvælvede sideflade af det rørformede fladagtige profil, der udgør friskluftventilens spjæld.In cases where the width of the bridges in the course of the duct sleeve is desired to be extended to maximum width, the end portions of the bridges facing the damper may be formed with a rounding corresponding to the second vaulted side surface of the tubular flat-like profile constituting the fresh air valve damper.
10 I den hensigt at tilvejebringe en glat og rengøringsvenlig overflade af friskluftventilen, kan endedelene omfatte en med den første hvælvede overflade af ventilationsspjældet, kongruent hvælvet overflade, herved fremstår ventildækslet og endedelene som et tilnærmelsesvist ubrudt forløb, der er let af aftørre med en 15 klud, i forbindelse med rengøring.In order to provide a smooth and easy-to-clean surface of the fresh air valve, the end portions may comprise a congruently vaulted surface with the first vaulted surface of the ventilation damper, thereby providing the valve cover and end portions as a substantially uninterrupted course of an easy wiping process. , in connection with cleaning.
I den hensigt at tilvejebringe en reduceret indbygningshøjde for friskluftventilen, samt en forenkling af de trykudløselige snapkoblinger, kan de respektive endedele omfatte et udragende parti orienteret modsat den hvælvede 20 overflade, hvilke partier er samvirkende med og indskydelige koblingsbrøndene, idet det udragende parti endedelen omfatter udstående styreknaster, der samvirker med styrespor i det mindste i to modstående og imod endedelenes tilvendende sider af henholdsvis den første- og den anden koblingsbrønd, og et endedelene yderligere omfatter et hulrum for optagelse af henholdsvis en 25 trykfjeder indeni hvilken er lejret det første ben af et i hovedsagen U-formet snapelement, således at trykfjederen hviler imod U-profilets bund, og hvilket U-formet snapelement i forlængelse af U-profilets bund yderligere omfatter en udstående holdeknast for optagelse i et dermed samvirkende udtag/hul i koblingsbrøndenes side, og hvor det U-formede snapelements andet ben omfatter 30 et udstående holdeknastorgan orienteret imod og optaget i et sporsystem omfattende et med det udragende partis længdeakse parallelt orienteret spor, hvis ene ende omfatter en labyrint omfattende et V-formet sporskifte hvis første spor er dybere end det andet, og i hvis midte findes opstående holdeparti med en imod det med det udragende partis længdeakse parallelt orienteret spor tilspidset forløb, 35 og hvis modsatte ende omfatter et med holdeknastorganet samvirkende, aftrappet leje, og hvor spordybden i det første spor, imellem det tilspidsede forløb og det aftrappede leje, er aftagende, og hvori holdeknastorganet ved indtrykning endedelene til en bundstilling, indstyres i det aftrappede leje, hvorved 6 DK 176163 B1 ventilationsspjældet midlertidigt arreteres i aktiv lukket position, antrykket imod læberingen, og hvor en gen-trykpåvirkning af en relevant endedel vil medføre at holdeknastorganet frigøres fra det aftrappede leje og styres sideværts og ind i et det V-formede sporskiftes andet spor, hvis bund er lavere beliggende, hvorved 5 holdeknastorganet frigøres fra det aftrappede leje, og føres via det andet spor, hvis dybde er aftagende imod det med det udragende partis længdeakse parallelt orienteret spor under udskydning af partiet til en åben passiv position for ventilationsspjældet.In order to provide a reduced recirculation height for the fresh air valve, and a simplification of the pressure-releasable snap couplings, the respective end portions may comprise a protruding portion oriented opposite the vaulted surface, which portions cooperate with and retractable coupling wells, the protruding portion end portion. control knobs cooperating with guide grooves at least in two opposite and opposite end portions of the first and second coupling wells respectively, and an end portions further comprising a cavity for receiving a compression spring within which is mounted the first leg of a substantially U-shaped snap member such that the compression spring rests against the bottom of the U-profile, and which U-shaped snap member further extends to the bottom of the U-profile further comprises a protruding retaining knob for accommodating a cooperating outlet / hole in the side of the coupling wells, and wherein the second leg of the U-shaped snap element 30 is a protruding retaining means oriented against and accommodated in a groove system comprising a longitudinal axis parallel to the protruding portion, one end of which comprises a maze comprising a V-shaped groove whose first groove is deeper than the other, and in the middle of which is raised holding portion having a tapered groove, parallel to the longitudinal axis of the protruding portion, 35 and the opposite end of which comprises a stepped bearing cooperating with the holding cam means and wherein the groove depth in the first groove between the tapered course and the stepped bearing is decreasing; and wherein, by pressing the end members to a bottom position, the holding cam is guided into the stepped bed whereby the ventilation damper is temporarily arranged in the active closed position, pressed against the lip ring, and where a repression of a relevant end part will result in the holding cam member being released from it. stepped bearings and steered laterally and into a det V -shaped second groove, the bottom of which is lower located, thereby releasing the holding cam means from the stepped bearing, and passing through the second groove, whose depth decreases against the longitudinal axis of the protruding portion parallel to the groove while pushing the portion into an open passive position of the ventilation damper.
10 Herved er der opnået en integrering af endestykkerne og de trykudløselige snapkoblinger, idet endestykkerne nu indgår som en integreret del af disse.Hereby an integration of the end pieces and the pressure-releasable snap couplings has been achieved, the end pieces now being an integral part of them.
Endvidere opnås der ved de udstående styreknaster på endedelen, der samvirker med styrespor i det mindste i to modstående og imod endedelenes tilvendende sider af henholdsvis den første- og den anden koblingsbrønd, en betydelig bedre 15 styring af disse under forskydningen af disse imellem yderpositionerne, og brugeren får derhev en fornemmelse af større stabilitet under betjeningen af friskluftventilen. Endvidere opnåes det ved den nye opbygning af friskluftsventilens trykudløselige snapkoblinger, ved det U-formede snapelement, der ved sin indretning løser flere opgaver, nemlig at holde spjældet fast i henholdsvis åben og 20 lukket position, samt fastholder endestykkerne, i koblingsbrøndene, hvilket samlet giver mulighed for en mindre indbygningshøjde for friskluftsventilen. Samtidigt er det ved den særlige udformning af de trykudløselige snapkoblinger opnået, at den fjeder, der ved trykpåvirkning af de trykudløselige snapkoblinger forskyder endestykkerne udefter i forhold til kanalbøsningen, og dermed også spjældet, 25 yderligere udnyttes til at fastholde holdeknastorganet i indgreb med det aftrappede leje for midlertidig arretering af spjældet i lukket position, i anlæg med tætningslisten.Furthermore, by the protruding control knobs on the end portion cooperating with guide grooves at least in two opposite and opposite end portions of the first and second coupling wells respectively, a significantly better control thereof is obtained during the displacement of these between the outer positions, and the user thereby gets a feeling of greater stability during the operation of the fresh air valve. Furthermore, by the new construction of the fresh air valve pressure-releasable snap couplings, it is achieved by the U-shaped snap element, which by its device solves several tasks, namely to hold the damper in the open and closed positions respectively, and hold the end pieces, in the coupling wells, which together provide the possibility of a smaller installation height for the fresh air valve. At the same time, in the particular design of the pressure-releasable snap couplings, it is achieved that the spring which, when pressurized by the pressure-releasable snap couplings, displaces the end pieces outwardly relative to the duct bushing, and thus also the damper, is further utilized to hold the retaining member in engagement with the stepped bearing. for temporary arrest of the damper in the closed position, in systems with the sealing strip.
