Abstract
Perfeccionamientos en accionadoes de válvulas en instalaciones de agua de alimentación y vapor de agua que se pueden montar sobre una válvula alineado con un vástago de válvula, cuyo vástago se mueve para abrir y cerrar la válvula, caracterizados porque se dota a cada accionador un cilindro hidráulico; un pistón montado deslizantemente dentro del cilindro; un vástago de pistón unido a un primer lado del pistón y que sale del cilindro hacia la válvula a través de una abertura en un primer extremo del cilindro para efectuar un movimiento hermético deslizante a través del mismo, cuyo vástago tiene un extremo prolongado que se puede unir al vástago de la válvula; y un acumulador tiene una pared de presión de forma generalmente esférica intersectada por el cilindro para situar un segundo extremo del cilindro dentro del acumulador con el fin de permitir la comunicación del interior del acumulador con un segundo lado de pistón.
