Abstract

LA INVENCION SE REFIERE A UN ACCIONAMIENTO HIDROSTATICO CON UN CIRCUITO HIDRAULICO CERRADO. SE HA COMPROBADO QUE LOS ACCIONAMIENTOS DE ESTE TIPO NO PUEDEN OPERARSE DE UNA FORMA EXACTA DEBIDO A LAS TOLERANCIAS CONSTRUCTIVAS Y DE DESGASTE. POR ELLO SE PROPONE UN DISPOSITIVO DE AJUSTE, ASI COMO UNA PROTECCION DE SOBRECARGA DEL ACCIONAMIENTO HIDROSTATICO.
