Abstract

Un actuador para válvulas de control de fluido con un módulo motriz invertible que tiene un elemento interno estacionario y un elemento externodesplazable alineado coaxialmente acoplado al elemento de control de flujo de la válvula ydespla zable deslizablemente sobre el elemento interno. Unacámara formada entre los respectivos extremos de los elementos incluye una vejiga preformada. Una presión neumática aplicada a la vejiga acciona elelemento desplazable para actuar laválvula en una primer dirección. Un resorte hace volver el elemento desplazable en la seguanda dirección. Lavejiga preformada está formada con dos partes que incluyen una porción perimétrica interconectante. Durante la actuación dela vejiga l a porciónperimétrica de la vejiga es desplazada del diámetro interno de la vejiga al diámetro externo de la vejiga con el material de la vejiga en tensión parade este modo prolongar la vida de la vejiga.
