Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE CONTROL DE UN GATO HIDRAULICO DE DOBLE EFECTO (10) QUE COMPRENDE EN UN CIRCUITO PRINCIPAL UN CONJUNTO DISTRIBUIDOR (28, 28'', 34, 34'') CONTROLADOS POR MEDIOS ELECTRICOS, Y QUE CONTROLA LA PUESTA EN RELACION DE LAS DOS CAMARAS DEL GATO (14, 16) DEPOSITO DE FLUIDO A BAJA PRESION (24), UN CIRCUITO AUXILIAR CONTROLADO POR MEDIOS (76) SENSIBLES A LA POSICION DEL PISTON (12) DEL GATO (10). SEGUN LA INVENCION, EL CIRCUITO AUXILIAR COMPRENDE UN DISTRIBUIDOR DE CORREDERA (50) QUE ASEGURA LA VUELTA DEL PISTON (12) DEL GATO (10) EN UNA POSICION DE REPOSO EN CASO DE FALLO DE LOS MEDIOS DE CONTROL ELECTRICOS ACCIONANDO EL CONJUNTO DISTRIBUIDOR (34, 34'') DEL CIRCUITO PRINCIPAL.
