Claims (4)
1. Indretning til at forhindre tilbagestrømning i ventilationskanaler i ventilationssystemer og yderligere spredning af brand og brandgasser gennem ventilationssystemet, omfattende et afstandsorgan (11) i form af et net (11') tilvejebragt med en flange (16) monterbar i en ventilationskanal (13) og dækkende dens gennemstrømningsområde, til hvilket afstandsorgan (11) en rørform (12) er forbundet, som har en forlængelse af længden i retningen af pågældende strøm og som består af et rør (12') fastgjort ved omkredsen på afstandsorganet (11) og hvilken rørform (12) omfatter et fleksibelt materiale og er åben i dens frie ende (15) og har en længde som er tilstrækkelig når den falder sammen i tilfælde af tilbagestrømning for at dække afsnitsområdet i ventilationskanalen (13) til at danne en forseglet støtte mod afstandsorganet (11).
2. Indretning ifølge krav 1, kendetegnet ved at afstandsorganet (11) og rørformen (12) forbundet dermed er fremstillet som et præfabrikeret stykke.
3. Indretning ifølge krav 1, kendetegnet ved at rørformen (12) er helt eller delvist skåret i dens længderetning.
4. Indretning ifølge krav 1, kendetegnet ved at røret (12') er konisk tilspidset i retningen mod dets frie ende (15).
