Abstract
LA INVENCION SE REFIERE A UN CIRCUITO DE ACCIONAMIENTO DE UN GATO HIDRAULICO DE DOBLE EFECTO (10) CONSTITUIDO POR UN PISTON (12) CONECTADO A UNA VARILLA DE SALIDA (18) Y QUE SEPARA UN CILINDRO EN DOS CAMARAS (14, 16), QUE COMPRENDE UNA FUENTE DE FLUIDO A PRESION (20, 26) PONIENDO UN SISTEMA DE DISTRIBUCION (28, 28'', 52, 52'') ALTERNATIVAMENTE UNA DE LAS CAMARAS O CAMARA DE ACCIONAMIENTO EN COMUNICACION CON LA FUENTE DE FLUIDO A PRESION (20, 26) Y LA OTRA CAMARA O CAMARA ACCIONADA EN COMUNICACION CON UN DEPOSITO DE FLUIDO A BAJA PRESION (25) PARA ACCIONAR EL MOVIMIENTO DEL PISTON (12) DEL GATO (10). SEGUN LA INVENCION, EL GATO COMPRENDE UN CIRCUITO AUXILIAR (50, 120, 122) PARA IMPEDIR LA COMUNICACION ENTRE LA CAMARA ACCIONADA Y EL DEPOSITO (25), INTERRUMPIR LA COMUNICACION ENTRE LA CAMARA DE ACCIONAMIENTO Y LA FUENTE DE FLUIDO A PRESION (20, 26) Y PERMITIR LA COMUNICACION ENTRE LAS CAMARAS ACCIONADAS Y DE ACCIONAMIENTO CUANDO LA PRESION DEL FLUIDO EN LA CAMARA ACCIONADA SOBREPASA UN VALOR PREDETERMINADO.
