Abstract

PARA OBTENER UNA MODIFICACION DE MULTIPLICACION CONTINUA DESDE FUNCIONAMIENTO DE SERVODIRECCION A FUNCIONAMIENTO DE DIRECCION DE EMERGENCIA, ASI COMO UN SUMINISTRO MAXIMO DE ACEITE EN FUNCIONAMIENTO DE SERVODIRECCION CON ELEVADO NUMEROS DE REVOLUCIONES DE DIRECCION, SE PROPONE UNA INSTALACION DE DIRECCION QUE UTILIZA UN LINEA COLECTIVA (34) QUE EVITA LA BOMBA DOSIFICADORA (14) COMO LINEA DE ENTRADA PARA INTENSIFICAR LA CORRIENTE EN FUNCIONAMIENTO SERVO Y COMO LINEA DE SALIDA PARA LA MODIFICACION DE MULTIPLICACION EN FUNCIONAMIENTO DE DIRECCION DE EMERGENCIA. ESTA LINEA COLECTIVA (34) ESTA UNIDA, A TRAVES DE UNOS ESTRANGULADORES (23), A UNAS LINEAS DE ENTRADA SELECCIONADAS (16) Y, A TRAVES DE UNOS ESTRANGULADORES (35, 37), A LAS LINEAS CILINDRICAS CORRESPONDIENTES (17) O A TODAS LAS LINEAS CILINDRICAS (17, 17''). ESTAS INSTALACIONES DE DIRECCION SE EMPLEAN EN INSTALACIONES MOVILES, EN ESPECIAL EN VEHICULOS DE MARCHA LENTA.
