Beschreibung
Zusammenfassung:	Disclosed herein is a gate valve design with a proportionally controlled orifice area. The moving element of the gate is shaped to cooperate with a fixed element so that as the gate opens, the open orifice area changes geometrically. La présente invention concerne une conception de robinet-vanne comportant une zone d'orifice régulée proportionnellement. L'élément mobile de la vanne est façonné pour coopérer avec un élément fixe de sorte qu'au fur et à mesure que la vanne s'ouvre, la zone d'orifice ouverte change géométriquement.
