CA 2281558
The conduit (5) includes a rotary fitting (11), and two segments (18, 19) elbow-connected to each other and each having an articulated mechanism (23, 24) including a pair of U-section bars (26, 27) connected to each other in the form of an articulated parallelogram by means of two articulated elements (37, 44; 44, 51). A spiral compression spring (35, 36) is housed between each pair of bars (26, 27), and is compressed between a disk (55), integral with one of the bars (26, 27), and a flange (64) sliding along a threaded rod (62). The flange (64) is locked on the rod (62) by means of a nut (67), and the rod (62) is connected to a lever member (69) pivoting on one of the articulated elements (37, 44) so as to adjust the action of the spring (35, 36) as a function of the angular position of the relative segment (18, 19) with respect to the articulated element (37, 44).
Ce conduit (5) comprend un raccord pivotant (11) ainsi que deux segments (18, 19), reliés l'un à l'autre de manière à former un coude et présentant chacun un mécanisme articulé (23, 24) comportant une paire de barres en U (26, 27) reliées l'une à l'autre sous la forme d'un parallélogramme articulé, au moyen de deux éléments d'articulation (37, 44; 44, 51). Un ressort de compression hélicoïdal (35, 36) est logé entre chaque paire de barres (26, 27) et est comprimé entre un disque (55) solidaire de l'une des barres (26, 27) et une embase (67) coulissant le long d'une tige filetée (62). L'embase (64) est verrouillée sur la tige (62) au moyen d'un écrou (67) et la tige (62) est reliée à un levier (69) pivotant sur l'un des éléments articulés (37, 44) de façon que l'action du ressort (35, 36) puisse être réglée en fonction de la position angulaire du segment relatif (18, 19) par rapport à l'élément articulé (37, 44).
