A quarter-turn valve includes a valve body having an inlet (32), an outlet (34), and a diaphragm (26) adjacent arranged in said valve body for movement between a closed and opened position for restricting and controlling fluid flow. The valve further includes an input shaft (24) for receiving a torsional input load in a closing direction and a torsional input load in an opposite opening direction. A cam (28) is mounted on the input shaft. The cam transforms input loads to linear output loads that flex the diaphragm between its closed and opened positions.
La présente invention concerne un robinet-vanne quart de tour, comprenant un corps de robinet-vanne ayant une entrée (32), une sortie (34) et une membrane (26) adjacente disposée dans ledit corps de robinet-vanne pour se déplacer entre une position ouverte et fermée permettant de limiter et de contrôler l~écoulement de fluide. Le robinet-vanne comprend en outre un arbre d~entrée (24) destiné à recevoir une charge d~entrée de torsion dans une direction de fermeture et une charge d~entrée de torsion dans une direction d~ouverture opposée. Une came (28) est montée sur l~arbre d'entrée. La came transforme les charges d'entrée en charges de sortie linéaires fléchissant la membrane entre ses positions ouverte et fermée.
