Abstract

L'invention concerne un compresseur à canaux latéraux comportant une roue à aubes (2) agencée de manière rotative dans un carter (3), laquelle est raccordée à un arbre d'entraînement pouvant tourner autour d'un axe de rotation géométrique (x). La roue à aubes (2) est positionnée dans le carter (3) de telle manière qu'entre le carter (3) et la roue à aubes (2) sont ménagées une fente radialement extérieure (11) et une fente radialement intérieure (13) qui doivent empêcher un contact entre la roue à aubes (2) et le carter (3) pendant le fonctionnement. La roue à aubes (2) présente par ailleurs un bord extérieur et intérieur fermé, et présente sur les deux côtés axiaux une pluralité d'aubes (5) agencées les unes après les autres dans une direction circonférentielle de la roue à aubes, ouvertes en direction d'une surface perpendiculaire à l'axe de rotation (x), et le bord extérieur forme une paroi circonférentielle (7) qui est associée à une paroi radiale (10) du carter (3) en formant la fente radialement extérieure (11). L'invention vise à perfectionner de façon avantageuse un compresseur à canaux latéraux ou une machine à canaux latéraux du type ci-dessus de manière à obtenir un meilleur rendement. À cet effet, dans la fente radialement extérieure (11), entre le bord extérieur fermé de la roue à aubes (2) et la paroi radiale (10) de la paroi de carter, sont collées, sur la circonférence, une ou plusieurs bandes d'étanchéité (14), qui présentent des faces plates (15) et qui sont composées d'un matériau qui, lors d'un éventuel contact avec la roue à aubes (2) en rotation, s'érode légèrement et empêche ainsi un blocage de la roue à aubes (2) au niveau de carter (3), les faces plates (15) de la bande d'étanchéité 14) s'étendant le long de la paroi radiale (10) du carter (3) et du bord extérieur de la roue à aubes (2).
