Abstract
EL OBJETO DE LA PRESENTE INVENCION ES LA DE UNA SERVODIRECCION PARA CONDUCIR EL ACEITE A PRESION A LAS CAMARAS DEL LADO IZQUIERDO Y DEL LADO DERECHO (6,7) DE UN SERVO-CILINDRO (3), A TRAVES DE UNA VALVULA DE CORREDERA GIRATORIA (9) CON UNA BOMBA (10), EN EL QUE SE HA INTERCALADO ENTRE UN EJE DE ENTRADA (14) Y UN CASQUILLO DE CONTROL (15) DE LA VALVULA DE CORREDERA GIRATORIA (9), UN EMBOLO DE REACCION (18) IMPULSADO POR UN RESORTE DE COMPRESION (19). CON EL FIN DE CREAR PARA ESTA SERVODIRECCION UN DISPOSITIVO DE REACCION HIDRAULICO DE FACIL CONSTRUCCION SE PROPONE, QUE EN UNA CONDUCCION (31) SE INTERCALEN ENTRE LA BOMBA (10) Y LA PARTE POSTERIOR DEL EMBOLO DE REACCION (18) IMPULSADO POR EL RESORTE DE PRESION (19), UNA VALVULA DE REGULACION DE PRESION PROPORCIONAL VDRV (30), PARA REDUCIR LA PRESION DEL SISTEMA (P) A UNA PRESION DE REACCION (P2) MAS BAJA, Y UNA TAPA (29) VARIABLE PARA LA REGULACION EN FUNCION DE LA VELOCIDAD DE UN PAR RETROACTIVO HIDRAULICO, Y QUE EN UNA CONDUCCION (PR) SE CONECTE ENTRE LA PARTE ANTERIOR DEL EMBOLO DE REACCION (18) Y UN DEPOSITO (27), UNA TAPA (34) VARIABLE PARA LA REGULACION EN FUNCION DE LA VELOCIDAD DE UNA PRESION DE RETORNO (PR).
