Abstract

The invention refers to an air-conditioning vent for a room or similar area. The vent is comprised of a horizontal duct, whose outward opening is shaped like a cut down cone, as well as a vent plate, whose jacket surface clings to the named opening and presents a similar form of a cut down cone. The vent plate can be cast off in the axial direction of the duct for adjustment of a cross-section of a first ring-shaped spring between the vent plate and the opening. In the duct there is an axial sound moderating cartridge made of soft, absorbent material, e.g. fibreglass, rock wool or cellular plastic. Between the cartridge and the duct there is a second axial spring. The cartridge in the individual opening is located with the end fixed at the vent plate so, that it moves itself together with this.<IMAGE>

Description

7808437-z s 2 Upptinningen har som ändamål att avlägsna de ovannämmla olñgenheterna och att åstadkonne en luftkonditioneringsventí1 av ny typ, san i Fråga om ljuddäwpandc egenskaper och användning i praktiken är betydligt tüttre än de hittills kända tyßerna. p V I UppFinningen är baserad på tanken att i ventilationskanalen placera en av mjukt, absorherande neterial bestående ljuddänpande patron, vars slutände-är så tjüßk. att de höga ljud, som söker sig ut genom den i ventilationskanalen kvar- stående avlånga springan eFFektivt dänpas. En förutsättning härvid är, att springans bredd är mindre än de ifrågavarande ljudens våglängd. 7808437-z s 2 The purpose of the thawing is to remove the above-mentioned nuisances and to provide an air conditioning valve of a new type, as in the case of sound attenuation properties and use in practice is considerably tüter than the hitherto known noises. The invention is based on the idea of placing in the ventilation duct a sound-absorbing cartridge consisting of soft, absorbent net material, the end of which is so thick. that the loud noises which seek out through the elongated gap remaining in the ventilation duct are effectively reduced. A prerequisite for this is that the width of the gap is smaller than the wavelength of the sounds in question.

Närnere bestämt är luFtkonditíoneringsventilen enligt uppfinningen i huvud- sak kännetecknad av en i kanalen axiellt anordnad ljwldünparpatron Franmtälld av nﬁukt, absorberande neterial, t.ex. glasull, hergull eller cellplast, varvid nellar patronen och kanalen bildas åtminstone en andra axiell springa, vars bredd är högst 30 mn. _ _ Det bör dock vid definiering av skyddsonfånget beaktas, att denna patent- beskrivning samt hitogade ritning på ett i patentlagen Vörutsett sätt i sin hel- het noteras.> _ Wed tillhjälp av upptinningen har man jämfört ned tidigare teknik ned enkla nedel åstamumnnit en synnerligen eF¥ektiv ljuddünpning och sahtidigt en enkel wöjlighet att byta ut dänparorganet. 7 Upptinningen betraktas nedan i detalj på basen av ut¥ñringsexcnplen enligt ritningen. * Figur 1 ¥ürestüller i snitt en i en relativt tjock vägg anonlnai ventil- konstruktion. _ _ Fiàur 2 Füreställer i snitt en i en relativt tunn vägg anordnad analog ventilkonstruktion. _ ' Figur 3 föreställer i partiellt snitt en ljuddünparpatron enligt upptin- ningen, sedd från sidan. I I utfüringsexenplet enligt Figur 1 onﬁattar ventilen en kanal, son består av en del_12 ned fornen av en stympad kon samt av en cy1inderFormad del 13, smn leder til1\entilationskanalen 10. Kanalen 12, 13 är vågrät. Ventiltallriken 1 onfattar en nantelyta, som ansmygande sig dot kanalens ñppningsdel 12 även har tornen av en stynpad kon. Den kan Förskjutas i kanalens 13 axialriktning på ett i sig känt sätt Fdr inställning av bredden av en Fdrsta ringfornnd springa 6 nallar ventiltallriken 1 och 2.More specifically, the air conditioning valve according to the invention is mainly characterized by a light-thin pair cartridge arranged in the duct. Made of wet, absorbent material, e.g. glass wool, man-made wool or cellular plastic, whereby the cartridge and the channel form at least one second axial gap, the width of which is not more than 30 mn. However, when defining the scope of protection, it should be taken into account that this patent description and the accompanying drawing are noted in their entirety in a manner foreseen in the Patents Act.> _ With the help of thawing, previous technology has been compared to simple parts. Effective sound attenuation and at the same time an easy opportunity to replace the dänper organ. 7 The thawing is considered below in detail on the basis of the design example according to the drawing. * Figure 1 ¥ ürestüller in section one in a relatively thick wall anonlnai valve construction. _ _ Fiàur 2 Shows on average an analog valve construction arranged in a relatively thin wall. Figure 3 is a partial sectional view of a sound down pair cartridge according to thawing, seen from the side. In the embodiment according to Figure 1, the valve assumes a channel, which consists of a part_12 down the front of a truncated cone and of a cylindrical part 13, which leads to the ventilation channel 10. The channel 12, 13 is horizontal. The valve plate 1 comprises a nant surface, which snuggles up so that the opening part 12 of the duct also has the towers of a truncated cone. It can be displaced in the axial direction of the channel 13 in a manner known per se. Before setting the width of a first ring-shaped gap 6, the valve discs 1 and 2 run.

I Enligt uttöringsexenplet är ljuddänparpatronen 2 i Form av en avlång cylin- der, som tillverkats av nüukt, ahsorberande material, Fäst i sin not öppningen 12_liggande ände på ett i sig känt sätt vid ventiltnllríken 1 så, att den rdr sig tillsawnens med densanna. Patronen är t.ex. tillverkad av glasull, hergull ' eller cellplast. Dess tvärsnittsyta Följer kanalens 13 tvärsnittsyta så, att 7808437-3 rrellan kcanalrzrn 13 (Joh patronen 2 bildas en andra axial ringïforwixnri springa 4, vars br-Ledd iir Lingge-Flir 15 Inn.

Patronens 2 andra ände sträcker sig nästan till venti Iationsskanalrens 10 mot kanalen '13 vända ände.According to the embodiment, the sounding cartridge cartridge 2 is in the form of an elongate cylinder made of soft, absorbent material. Attach to its groove the end 12 lying in a manner known per se to the valve ring 1 so that it is aligned with the same. The cartridge is e.g. made of glass wool, hergull 'or cellular plastic. Its cross-sectional area Follows the cross-sectional area of the channel 13 so that 7808437-3 rrellan kcanalrzrn 13 (Joh cartridge 2 forms a second axial ringïforwixnri slot 4, whose br-Ledd iir Lingge-Flir 15 Inn. The other end of the cartridge 2 extends almost to the end of the vent duct 10 facing the duct '13.
