Abstract

L'invention concerne un segment de canal d'écoulement (S), notamment pour un aspirateur (1), comprenant une articulation tournante (18) et un segment diagonal intermédiaire (15) formé à partir d'un canal d'entrée, qui, de nouveau par une autre déviation, débouche dans un canal de sortie, la section du canal d'entrée (13) et du canal de sortie (17) étant elliptique, l'articulation tournante (18) étant formée dans le segment intermédiaire (15), et la section du canal étant circulaire. Afin d'obtenir un segment de canal d'écoulement (S) destiné notamment à un aspirateur, selon l'invention, qui permette que les meilleures conditions d'écoulement possibles soient maintenues sur la plus grande plage possible de pivotement autour de l'articulation tournante (18) et/ou que le flux d'air (L) soit dévié de façon que des zones de déviation brusques soient évitées, et d'obtenir également un segment de canal d'écoulement (S) relativement petit, il est proposé que le segment intermédiaire (15) suive une ligne sensiblement en diagonale dans l'espace (axe x).
