Abstract

Perfeccionamientos en los aparatos fluidodinámicos de posiciones múltiples, caracterizados porque el aparato comprende: a. un cilindro, b. una pluralidad de pistones que forman cámaras dentro de dicho cilindro y que responden a presiones de fluido para moverse en pasos separados cuando las presiones dentro de dichas cámaras superan niveles predeterminados, c. un elemento de accionamiento que responde a los movimientos de cualquiera de dichos pistones, d. medios de fuerza para mantener normalmente dichos pistones en posiciones no activadas cuando las presiones de fluido aplicadas a dichas cámaras están por debajo de dichos niveles predeterminados. e. una fuente de fluido a presión y f. una pluralidad de dispositivos biestables conectados a cámaras correspondientes para conectar selectivamente dicha fuente de fluido bajo presión a las mismas a fin de mover dichos pistones en pasos individuales cuando las presiones de fluido superan niveles predeterminados, con lo que se mueve dicho elemento de accionamiento en distancias separados predeterminadas de acuerdo con los pistones accionados.
