Abstract

L'invention concerne un ventilateur (1) lequel est notamment destiné à être mis en œuvre dans l'exploitation minière et la construction de tunnels et lequel dispose d'un boîtier de ventilateur (2) tubulaire dont la paroi intérieure (5) est pourvue d'une manière précise d'ouvertures de transmission du son (24, 25). Les ouvertures de transmission du son (24, 25) présentent généralement une disposition annulaire tout en préservant une enveloppe annulaire (23) au niveau du segment (16) qui supporte la roue de ventilateur (9) et le dispositif d'entraînement (10), pour ainsi assurer un agencement sûr et précis de ces deux pièces structurales. Les autres zones ne sont pas pourvues d'une paroi intérieure (5), la paroi extérieure (4) et/ou la paroi d'accouplement (3) y étant réalisées de manière à compenser, en tant que telles, l'effet desdites ouvertures de transmission du son.
