Abstract
Un dispositivo de control que es actuado por presión, que comprende: a) una caja de sustentación que define una porción de superficie de reacción. B) un órgano de control soportado por la mencionada caja de sustentación y móvil con relación a la mencionada porción de superficie de reacción entre la primera y segunda posiciones, estando desviado el mencionado órgano de control hacia la mencionada posición primera. C) una cámara de aire interpuesta funcionalmente entre el mencionado órgano de control y la mencionada porción de superficie de reacción para efectuar movimiento del mencionado órgano de control hacia la segunda posición ya mencionada a partir de la primera posición, estando formada esta cámara de aire por lo menos en parte por un material peculiar flexible y construida y dispuesta para ser hinchable hasta alcanzar un volumen predeterminado sin deformar elásticamente el material pelicular. D) medios de conducción para comunicar el interior de dicha cámara de aire con una fuente defluido de manera que la cámara de aire se infla con tendencia a alcanzar el mencionado volumen predeterminado cuando el nivel de la presión del fluido en dicha cámara de aire rebasa la presión ambiente de dicha cámara. E) la mencionada cámara de aire que engrana y transmite fuerza al mencionado órgano de control para mover el mencionado órgano de control a la segunda posición ya señalada cuando el volumen de dicha cámara de aire es considerablemente menor que el mencionado volumen predeterminado.
