Title (EN) STEM FOR TWO-WAY VALVE
(FR) STEM POUR VALVE À DEUX VOIES
Abstract:
(EN) The invention concerns a stem (1) for a two-way valve, the stem comprising a main body (10) having an external face that is substantially cylindrical about a main axis and having • a first tubular wall (11) that is closed at the bottom end of same by a first bottom wall (13) and open at the top end (111) of same, defining a central channel (113); • a second tubular wall (12) concentric with the first tubular wall (11) and partially surrounding it, the second tubular wall (12) being closed at the bottom end (122) of same by a second bottom wall (14) and open at the top end (121) of same, defining an annular channel (123) positioned around the central channel (113), one or more through-holes (124) bringing the inside of the annular channel (123) into contact with the cylindrical external face of the main body (10), • means for reinforcing the first tubular wall (11) in order to increase the stability of same when filling a container provided with a two-way valve equipped with the stem. According to the invention, the reinforcing means are constituted by a tubular insert (20) dimensioned so as to be able to be inserted into the annular channel (123) and fill, at least over a portion of the height of same, the space situated between the second bottom wall (14) and the lower portion of the through-hole or holes (124) of the second cylindrical wall (12).
(FR) L'invention concerne un stem (1) pour valve à deux voies, le stem comprenant un corps principal (10) ayant une face extérieure sensiblement cylindrique autour d'un axe principal et présentant • une première paroi tubulaire (11) fermée à son extrémité inférieure par une première paroi de fond (13) et ouverte à son extrémité supérieure (111) en définissant un canal central (113); • une deuxième paroi tubulaire (12) concentrique à la première paroi tubulaire (11) et l'entourant en partie, la deuxième paroi tubulaire (12) étant fermée à son extrémité inférieure (122) par une deuxième paroi de fond (14) et ouverte à son extrémité supérieure (121) en définissant un canal annulaire (123) placé autour du canal central (113), un ou plusieurs trous traversants (124) mettant en contact l'intérieur du canal annulaire (123) et la face extérieure cylindrique du corps principal (10), • des moyens de renfort de la première paroi tubulaire (11) pour renforcer la stabilité de celle-ci lors du remplissage d'un récipient muni d'une valve à deux voies équipée du stem. Conformément à l'invention, les moyens de renfort sont constitués par un insert (20) tubulaire dimensionné pour pouvoir être introduit dans le canal annulaire (123) et remplir, au moins sur une partie de sa hauteur, l'espace situé entre la deuxième paroi de fond (14) et la partie inférieure du ou des trous traversants (124) de la deuxième paroi cylindrique (12).
