Abstract
LA PRENSA LLEVA UN REGLON INFERIOR MOVIL ACCIONADO MEDIANTE TRES GATOS HIDRAULICOS (5A, 5B, 5C) DE LOS CUALES DOS ESTAN DISPUESTAS EN LAS EXTREMIDADES LATERALES DEL REGLON MOVIL Y AL MENOS UNO EN EL CENTRO SEGUN EL EJE DE ESTE. EL CIRCUITO HIDRAULICO ESTA ASOCIADO A UN DISPOSITIVO DE DETECCION DE LA EVENTUAL PRESENCIA DE UN PAR DE VOLCADO SOBRE EL REGLON MOVIL (2); Y A UN SISTEMA DE COMPARACION Y CALCULADOR UNIDO AL DISPOSITIVO DE DETECCION. LOS GATOS (5A, 5B, 5C) ESTAN CONECTADOS A UN DISTRIBUIDOR DIRECCIONAL COMUN (12) MEDIANTE UNOS MEDIOS DE CONTROL DE PRESION (15A, 15B, 15C) ACCIONADOS POR EL SISTEMA DE COMPARACION Y CALCULADOR, SIENDO ESTE APTO PARA ACCIONAR UNA REDUCCION EN CONTINUO DE LA PRESION EJERCIDA SOBRE EL GATO (5A O 5B) COLOCADO EN EL LADO OPUESTO A LA DIRECCION DEL PAR DE VOLCADO, Y EVENTUALMENTE TAMBIEN SOBRE EL GATO (5C) COLOCADO EN EL CENTRO, DE MANERA A CREAR UN PAR ANTAGONISTA AL PAR DE VOLCADO.
