Title
(EN) MICROVALVE FOR CONTROLLING FLUID FLOW
(FR) MICROVALVE DE REGULATION DE DEBIT
Abstract
(EN) A microvalve (10) for controlling fluid flow, including a body portion (14) having at least one opening (18) formed therein, a shutter (12) located adjacent to and substantially parallel with the body portion, and a drive mechanism (20, 22) for causing the shutter to pivot with respect to the body portion so that the shutter is brought into and out of alignment with the opening of the body portion, wherein the microvalve is in a closed position and an open position, respectively.
(FR) Cette invention concerne une microvalve (10) de régulation de débit comprenant une partie corps (14) qui présente au moins une ouverture (18), un volet située contre la partie corps et sensiblement parallèle à cette dernière, et un mécanisme d'entraînement (20, 22) faisant pivoter le volet (12) par rapport à la partie corps et l'amenant en face ou non de l'ouverture de la partie corps selon que la valve est en position ouverte ou fermée.
