Abstract

LA INVENCION TRATA DE UN CUERPO HUECO DE MATERIAL ELASTICO CON ELEMENTOS DE VENTILACION PARA SER FIJADO EN UN TUBO DE PAREDES LISAS, PARTICULARMENTE UN FUELLE PARA EL VASTAGO DE UN AMORTIGUADOR. PARA ASEGURAR UNA FIJACION DEL CUERPO HUECO EN LAS PAREDES LISAS DE UN TUBO CON GRAN FUERZA DE SUJECION, SE PROPONE QUE EL CUERPO HUECO (1) TENGA AL MENOS UNA ZONA EXTREMA (2) PARA SER PUESTA MEDIANTE DILATACION SOBRE EL TUBO (3), Y QUE LA ZONA EXTREMA TENGA EN LA CARA INTERIOR AL MENOS DOS FILAS DE ALMAS (4) OBLONGAS, EXTENDIENDOSE PRINCIPALMENTE EN DIRECCION DEL CONTORNO, Y QUE TANTO LAS ALMAS VECINAS (4) DE UNA FILA COMO TAMBIEN LAS FILAS ESTEN DISPUESTAS A UNA DISTANCIA ENTRE SI, Y QUE LAS ALMAS (4) DE FILAS VECINAS ESTEN DISPUESTAS ALTERNANDOSE, DE MODO QUE SE FORMEN CANALES DE VENTILACION LABERINTICOS.THE INVENTION IS ABOUT A HOLLOW BODY OF ELASTIC MATERIAL WITH VENTILATION ELEMENTS TO BE FIXED IN A SMOOTH WALL TUBE, PARTICULARLY A BELLOWS FOR A SHOCK ABSORBER STEM. TO ENSURE A FIXING OF THE HOLLOW BODY IN THE SMOOTH WALLS OF A TUBE WITH GREAT CLAMPING FORCE, IT IS PROPOSED THAT THE HOLLOW BODY (1) HAVE AT LEAST ONE EXTREME ZONE (2) TO BE POSTED BY DILATION ON THE TUBE (3), AND THAT THE EXTREME ZONE HAS AT LEAST TWO ROWS OF SOULS (4) OBLONGS, SPREADING MAINLY IN THE DIRECTION OF THE CONTOUR, AND THAT AS SOON AS NEIGHBORHOODS (4) OF A ROW ARE ALSO A DISTANCE BETWEEN YES, AND THAT THE SOULS (4) OF NEARBY ROWS ARE ARRANGED ALTERNATING, SO THAT LABYRINTIC VENTILATION CHANNELS ARE FORMED.
