Abstract
MANGUERA EXTENSIBLE, EN PARTICULAR PARA SISTEMAS DE DIRECCION SERVO ASISTIDOS EN VEHICULOS A MOTOR, QUE COMPRENDE UNA MANGUERA DE PRESION EXTERNA CON ALTA DILATACION TRANSVERSAL QUE VA CONECTADA A UNA PIEZA FINAL EN EL LADO DE ENTRADA Y A UNA PIEZA FINAL EN EL LADO DE SALIDA, Y UN CUERPO HUECO FLEXIBLE INTERNO DISPUESTO COAXIALMENTE CON LA MANGUERA DE PRESION EXTERNA, QUE SE CONECTA EN EL LADO DE ENTRADA A UNA PUA PARA TUERCAS DE RADIOS EN EL LADO DE ENTRADA DEL EXTREMO, Y SE EXTIENDE LIBREMENTE EN EL CANAL DE SALIDA DE LA PIEZA FINAL DEL LADO DE SALIDA. EL DIAMETRO EXTERNO DEL CUERPO HUECO FLEXIBLE INTERNO ES MENOR QUE EL DEL CANAL DE SALIDA QUE LE RODEA. EL HUECO ANULAR RESULTANTE FUERZA AL MEDIO HIDRAULICO DE VUELTA AL ESPACIO ENTRE LA MANGUERA DE PRESION EXTERNA Y EL CUERPO HUECO FLEXIBLE INTERNO. ADEMAS, EL MEDIO HIDRAULICO FLUYE EN ESTE ESPACIO A TRAVES DEL CUERPO HUECO FLEXIBLE INTERNO EN PASAJES RADIALES INTERESPACIADOS AXIALMENTE. LA MANGUERA EXTENSIBLE ES MAS SENCILLA QUE LAS MANGUERAS EXTENSIBLES CONOCIDAS PORQUE SE DISPENSA CON UNA OBSTRUCCION CENTRAL. SE CONSIGUE LA ATENUACION DE PULSACIONES DE PRESION DESEADA POR MEDIO DEL CUERPO HUECO FLEXIBLE INTERNO QUE SE EXTIENDE A LA PIEZA DEL EXTREMO DEL LADO DE LA SALIDA.
