Title
(EN) FLUID FLOW CONTROL DEVICE HAVING A DRAINING BODY BEARING
(FR) DISPOSITIF DE COMMANDE D'ÉCOULEMENT DE FLUIDE AYANT UN PALIER DE CORPS DE DRAINAGE
Abstract
(EN)
A fluid flow control device includes a valve body forming a channel defining a fluid flow path extending from an inlet to an outlet, a shaft having a first portion and a second portion, a flow control member coupled to the first portion of the shaft, and a bearing (150) comprising an elongated body (152) having a first end (154), a second end (156), an inner surface (158) defining an interior volume (159), and an outer surface (160). The bearing is dimensioned to accommodate the shaft in the interior volume and includes at least one opening (166) extending between the inner surface and the outer surface and at least one elongated channel (170) formed on the outer surface. The elongated channel extends a length between the first end and the second end of the elongated body.

L'invention concerne un dispositif de commande d'écoulement de fluide comprenant un corps de soupape formant un canal délimitant un trajet d'écoulement de fluide s'étendant d'une entrée à une sortie, un arbre ayant une première partie et une seconde partie, un élément de commande d'écoulement relié à la première partie de l'arbre, et un palier (150) comprenant un corps allongé (152) ayant une première extrémité (154), une seconde extrémité (156), une surface interne (158) délimitant un volume intérieur (159) et une surface externe (160). Le palier est dimensionné pour recevoir l'arbre dans le volume intérieur et comprend au moins une ouverture (166) s'étendant entre la surface interne et la surface externe et au moins un canal allongé (170) formé sur la surface externe. Le canal allongé s'étend sur une longueur entre la première extrémité et la seconde extrémité du corps allongé.
