Abstract

LAS UNIDADES DE DIRECCION DE TIPO PREVIO CONOCIDAS SUFREN DE PERDIDAS DE POTENCIA RELATIVAMENTE ALTAS, PARA ALIMENTAR UN FLUIDO HIDRAULICO DENTRO DEL CIRCUITO DE TRABAJO, SIENDO NECESARIO TRABAJAR CONTRA UN RESORTE DE COMPRESION CON UNA RELACION DE RESORTE ALTA. EL OBJETIVO DE LA INVENCION ES ALCANZAR UN NIVEL DE PRESION DE SEÑAL DE CARGA PARA SATISFACER ESTE REQUERIMIENTO. EL OBJETIVO SE CONSIGUE MEDIANTE DISPOSICION DE UNA VIA (24) COMUN PARA LA CONDUCCION AUXILIAR QUE DISCURRE A PARTIR DE LA LINEA PRINCIPAL A LA TERMINAL (12) DE RETORNO Y DISCURRIENDO LA LINEA AUXILIAR HACIA LA TERMINAL (13) DE SEÑAL DE CARGA. INSTALADO EN SERIE CON LA VIA COMUN SE DISPONE DE UN ESTRANGULADOR (26) Y DE OTRO ESTRANGULADOR (27) DE SEÑAL DE CARGA AJUSTABLE, DISPONIENDO EL ESTRANGULADOR (27) DE SEÑAL DE CARGA Y EL ESTRANGULADOR (20) DE ENTRADA AJUSTABLE DE CARACTERISTICAS DE ESTRANGULACION, QUE ACTUAN EN LA MISMA DIRECCION. LAS UNIDADES DE DIRECCION DE ESTE TIPO SON ADECUADAS PARA UTILIZACION EN SISTEMAS HIDRAULICOS MOVILES.
