Patent

CA 2627825

The invention relates to a draw-off valve (1) for a drinks reservoir (2). The draw-off valve comprises: a tubular body (3) comprising therein a channel (6) extending from an inlet (4) to an outlet (5) ; a plunger member (7) comprising a stem (8) and a head (9) , the head being oriented toward the inlet and the stem extending from the head, through the channel, to the outlet; and a spring member (10) . Viewed in the direction of passage, the channel narrows, at an internal narrowing (11), from a first internal cross section (Dl) to a second internal cross section (D2), the narrowing forms a seat (12) for the underside (13), facing the outlet, of the head. The spring member acts with bias, on the one hand, on the tubular body and, on the other hand, on the plunger in order to press the underside of the head against the seat. The seat and the underside of the head are formed in such a way that, when positioned against each other under the influence of the biasing of the spring member, they form a sealing closure of the channel. The invention further relates to a drinks reservoir provided with a draw-off valve of this type.

La présente invention concerne un robinet de vidange pour un réservoir à boissons. Le robinet de vidange comprend : un corps tubulaire qui comprend dans celui-ci un canal qui s~étend d~une entrée à une sortie ; un élément de piston plongeur qui comprend une tige et une tête, la tête étant orientée vers l~entrée et la tige s~étendant à partir de la tête, à travers le canal, jusqu~à la sortie ; et un élément de ressort. Vu dans la direction de passage, le canal rétrécit, au niveau d~un rétrécissement interne, d~une première section transversale interne à une seconde section transversale interne ; le rétrécissement forme un siège pour la sous-face, tournée vers la sortie, de la tête. L~élément de ressort agit avec sollicitation, d~une part, sur le corps tubulaire et, d~autre part, sur le piston plongeur afin de comprimer la sous-face de la tête contre le siège. Le siège et la sous-face de la tête sont formés de manière telle que, lorsqu~ils sont positionnés l~un contre l~autre sous l~influence de la sollicitation de l~élément de ressort, ils forment une fermeture d~étanchéité du canal. L~invention concerne en outre un réservoir à boissons pourvu d~un robinet de vidange de ce type.
