Abstract

Dispositivo de gato de fluido que comprende, en una cámara, una pared móvil que delimita, en esta cámara, dos compartimientos, uno de los cuales recibe el fluido motor, mientras que el otro disminuye de volumen durante la expansión de este fluido motor, caracterizado porque este último compartimiento está mantenido, previamente a cualquier desplazamiento de la pared, bajo vacío, mientras que el conjunto del equipo móvil asociado a esta pared está mantenido por un enclavamiento de liberación instantánea.
