Abstract

LA INVENCION SE REFIERE A UN CONTROLADOR DE REDUCTOR PARA UN REDUCTOR SYNCHRO-SHUTTLE (1) O REDUCTOR DE CAMBIO DE DIRECCION (2), ESPECIALMENTE PARA UNA MAQUINA DE TRABAJO, QUE PRESENTA ELEMENTOS DE CAMBIO PARA UNA MARCHA DE AVANCE (SEV1, SEV2) O DE RETROCESO (SER) Y DISPOSITIVOS DE CAMBIO PARA EL ACCIONAMIENTO DE UNA VALVULA DE CAMBIO (SV1) PARA LA SELECCION DE LA DIRECCION. ENTRE LOS ELEMENTOS DE CAMBIO PARA UNA MARCHA DE AVANCE O UNA MARCHA DE RETROCESO Y LA VALVULA DE CAMBIO PARA LA SELECCION DE LA DIRECCION, QUE PUEDE ACCIONARSE POR LOS DISPOSITIVOS DE CAMBIO, SE INSTALA UNA VALVULA DE CONTROL (SV2), QUE PUEDE SER ACCIONADA POR UN DISPOSITIVO DE CAMBIO ADICIONAL. LA VALVULA DE CONTROL PUEDE UTILIZARSE SELECTIVAMENTE COMO UNA VALVULA DE PUNTO MUERTO O MARCHA EN VACIO EN UN REDUCTOR SYNCHRO-SHUTTLE O COMO VALVULA DE CONMUTACION PARA LOS ELEMENTOS DE CAMBIO PARA UNA MARCHA DE AVANCE EN UN REDUCTOR DE CAMBIO DE DIRECCION.
