Abstract

SE TRATA DE UN ACCIONAMIENTO REGULADOR (1) PARA UNA VALVULA REGULADORA (2) CON UN CIRCUITO REGULADOR Y CONSTA DE UN CILINDRO PRINCIPAL (5) CON SU EMBOLO (6) DESPLAZABLE. EN UNA DE LAS CARAS DE ESTE EMBOLO SE ENCUENTRA EL VOLUMEN DE ACCIONAMIENTO COMPUESTO DE ACEITE BAJO PRESION Y EN LA OTRA CARA, EL VOLUMEN AMORTIGUADOR LLENADO TAMBIEN DE ACEITE (8). EL ACCIONAMIENTO REGULADOR (1) DEBE SER CONSEGUIDO A PESAR DE LA ALTA POTENCIA DE CARGA Y COMPARATIVAMENTE OFRECER UNA ALTA DINAMICA ESPECIALMENTE MEDIANTE EL CERRADO DE LA VALVULA REGULADORA (2). ESTO SE CONSIGUE YA QUE EL VOLUMEN DE ACCIONAMIENTO (7) Y EL VOLUMEN DE AMORTIGUACION (8) ESTAN CONECTADAS A TRAVES DE UNA VALVULA SITUADA EN LA TUBERIA DE CONEXION (22). ESTA VALVULA ES ACCIONADA A TRAVES DE UNA SEGUNDA VALVULA HIDRAULICAMENTE.
