Title (EN) LIQUID DISPENSING SYSTEM WITH IMPROVED SEALING AUGERING SCREW AND METHOD FOR DISPENSING
(FR) PROCEDE ET SYSTEME DE DISTRIBUTION DE LIQUIDE COMPORTANT UNE VIS D'ETANCHEITE A CUILLER
Abstract:
(EN) A liquid dispenser has an augering screw (16) that serves both a metering function and a valving function. The augering screw (16) is axially movable between a position in which fluid can flow (1B) and a sealing position (dashed line fig. 2) in which liquid flow through the nozzle is substantially prevented. The screw (16) is preferably designed with a curved contour (fig. 7b) between the threads (190) and with a plurality of thread-defining channels (fig. 7c) to allow liquid to fill more completely around the screw and to dispense more liquid with fewer screw turns than prior screw designs.
(FR) Distributeur de liquide comportant une vis à cuiller (16) possédant à la fois une fonction de mesure et une fonction de distribution. Cette vis (16) peut se déplacer sur un axe entre une position dans laquelle le liquide peut s'écouler (1B) et une position d'obturation (ligne pointillée, figure 2) dans laquelle l'écoulement de liquide à travers l'ajutage est pratiquement arrêté. Cette vis (16) présente, de préférence, un profil incurvé (fig. 7b) entre les filets (190) et comporte une pluralité de canaux définissant les filets (fig. 7c) afin de permettre au liquide de remplir de façon plus complète les espaces autour de la vis et de distribuer davantage de liquide avec moins de tours de vis que dans la conception de l'état actuel de la technique.
