Abstract

L'invention concerne un ensemble soufflante comprenant un boîtier de soufflante, un boîtier de diffuseur fixé au boîtier de soufflante et un diffuseur logé dans le boîtier de diffuseur. Une rainure d'étanchéité triangulaire fermée comportant trois surfaces d'étanchéité est formée entre le boîtier de soufflante, le boîtier de diffuseur et le diffuseur. Le boîtier de soufflante, le boîtier de diffuseur et le diffuseur forment respectivement une des trois surfaces d'étanchéité. Dans la rainure d'étanchéité triangulaire fermée est placé un élément d'étanchéité qui étanchéifie le boîtier de soufflante, le boîtier de diffuseur et le diffuseur les uns vis-à-vis des autres.
