Abstract

L'invention concerne une conduite annulaire (8) délimitée par deux tubes (12,13) dont les axes (2) sont parallèles et qui sont mobiles axialement l'un par rapport à l'autre, un premier tube (12) portant des organes de déviation (17) adaptés à conférer une composante tangentielle à une première partie d'un fluide se déplaçant dans la conduite (8), le deuxième tube (13) étant conformé de sorte que l'angle de déviation tangentielle de la première partie du fluide à l'extrémité aval de la conduite (8) dépend de la position axiale relative des deux tubes (12,13).The invention relates to an annular duct (8) delimited by two tubes (12, 13) whose axes (2) are parallel and which are axially movable with respect to each other, a first tube (12) carrying deflection members (17) adapted to impart a tangential component to a first portion of a fluid moving in the conduit (8), the second tube (13) being shaped such that the tangential deflection angle of the first portion fluid at the downstream end of the pipe (8) depends on the relative axial position of the two tubes (12,13).

Selon l'invention, le second tube (13) comprend des organes de redressement (19) qui sont adaptés à permettre à la partie complémentaire du fluide se déplaçant dans la conduite (8) d'avoir, à l'extrémité aval de la conduite (8), un angle de déviation tangentielle qui lui est propre.

Figure imgaf001
According to the invention, the second tube (13) comprises rectifying members (19) which are adapted to allow the complementary part of the fluid moving in the pipe (8) to have, at the downstream end of the pipe (8), a tangential deflection angle of its own.
