A bearing assembly for relatively moveable pipe sections in a fluid delivery system, said assembly comprising a main body (12) adapted to be connected to one end of one pipe section, the main body having in a generally radially extending annular face, a coaxial seat (16), to receive a first, generally annular bearing member (17), and a coaxial groove (18) to receive an annular seal member (19), an annular center swivel section (21) adapted to be connected to one end of a second pipe section and having on one generally radially extending face, a coaxial seat (22) to engage said first bearing member and having a second coaxial seat (23) on an opposed generally radially extending face to receive a second annular bearing member (24), said swivel section including an annular, axially extending boss (28) extending away from said main body with the opposed generally radially extending face extending radially outwardly from said boss, and a bearing end cap (26) adapted to engage around said second pipe section and be fastened to said main body sandwiching said swivel section and bearing members, said end cap having a seat (35) for said second bearing member, and a second seal member (31) disposed between said end cap and said swivel section.

L'invention concerne un ensemble de support des sections relativement amovibles d'un tuyau d'un système de distribution de liquide. Ledit ensemble comprend un corps principal (12) adapté pour être connecté à une extrémité d'une section du tuyau. Le corps principal comprend dans une face annulaire s'étendant généralement radialement un siège coaxial (16) destiné à recevoir un premier élément de support (17) généralement annulaire, une rainure coaxiale (18) destinée à recevoir un élément d'étanchéité annulaire (19), et une section centrale annulaire orientable (21) adaptée pour être connectée à une extrémité de la seconde section du tuyau et présentant sur une face s'étendant généralement radialement un siège coaxial (22) destiné à venir en contact avec ledit premier élément de support, et comprenant un second siège coaxial (23) sur une face opposée s'étendant généralement radialement et destiné à recevoir un second élément de support annulaire (24). Ladite section orientable comprend une partie annulaire (28) en relief s'étendant en direction axiale à l'opposé du corps principal, la face opposée s'étendant généralement radialement vers l'extérieur de la partie en relief. Un bouchon (26) d'extrémité de support est adapté pour venir se positionner autour de la seconde section du tuyau et être fixé au corps prinicipal, prenant en sandwich la section orientable et les éléments de support, ce bouchon d'extrémité comprenant un siège (35) pour ledit second élément de support. Un second élément d'étanchéité (31) est disposé entre le bouchon d'extrémité et la section orientable.
