Abstract

Il est décrit un actionneur de fluide de régulation à action proportionnelle qui est utilisé comme dispositif de positionnement dans des applications comme une valve de commande hydraulique et directrice. Lactivateur a un boîtier de cylindre pouvant être fixé à un boîtier de soupapes, et il a un alésage avec un piston qui est fixé, de manière coaxiale, à une extrémité dun tiroir. Le dispositif est fourni avec des ouvertures espacées dans le boîtier de cylindre communiquant avec lalésage qui sy trouve afin dintroduire du fluide afin dagir sur des côtés opposés du piston. Des moyens de garde montante de compression sont fournis pour encourager, normalement, une position centrale du piston et du tiroir. Étant donné que les zones de la pression de fluide appliquée sur les deux côtés du piston sont différentes (en raison dun tiroir sur un côté du piston), deux gardes montantes de pré-compression sont utilisées pour compenser la différence de zone afin datteindre un mouvement proportionnel du tiroir.
