Abstract

Ce robinet, notamment à pointeau, du type qui comprend un corps 10, un pointeau 16, un conduit d'entrée 18 et un conduit de sortie 20 séparés par un siège 14, est muni d'une garniture d'étanchéité 28, 32 dont la longueur effective L est supérieure à la course axiale maximale E de réglage du pointeau 12. Cette caractéristique évite que des éléments étrangers, par exemple des microbes, qui se sont infiltrés jusque dans la zone 46 du corps et adhèrent à cette zone ne se trouvent en position intérieure par rapport à la garniture d'étanchéité lorsque le pointeau est en position d'ouverture maximale. De tels robinets trouvent une application particulièrement avantageuse pour les aiguilles de perfusion.This valve, in particular a needle valve, of the type which comprises a body 10, a needle 16, an inlet duct 18 and an outlet duct 20 separated by a seat 14, is provided with a seal 28, 32 of which the effective length L is greater than the maximum axial travel E for adjusting the needle 12. This characteristic prevents foreign elements, for example microbes, which have infiltrated into zone 46 of the body and adhere to this zone are not found. in position inside with respect to the seal when the needle is in the maximum open position. Such taps find a particularly advantageous application for infusion needles.
