Abstract
UN DISPOSITIVO DE CONTROL ELECTROHIDRAULICO PARA UN REDUCTOR DE CAMBIO DE DIRECCION, ESPECIALMENTE PARA MAQUINAS DE TRABAJO, PRESENTA ELEMENTOS DE CAMBIO (SE1, SE2, SE3) QUE PUEDEN SER ACCIONADOS POR UNA PRESION DEL SISTEMA DE UNA FUENTE DE PRESION EXTERNA (1). PARA ELLO SE COLOCAN VALVULA DE CONMUTACION (SV1, SV2, SV3) ENTRE LA FUENTE DE PRESION (1) Y LOS ELEMENTOS DE CAMBIO (SE1, SE2, SE3), QUE PUEDEN ACCIONARSE MEDIANTE UNA PRESION DE CONTROL PREVIA. CADA UNO DE LOS ELEMENTOS DE CAMBIO (SE1, SE2, SE3) PUEDE ACCIONARSE EN UN ESTADO DEFINIDO POR AL MENOS DOS VALVULAS DE CONMUTACION (SV1, SV2, SV3) Y POR AL MENOS UNA VALVULA DE CONMUTACION NO ACCIONADA.
