Abstract

CE DISPOSITIF COMPREND UN SOUFFLET DILATABLE 46 AGISSANT EN REPONSE A LA PRESSION DE L'AIR DANS LE PNEUMATIQUE POUR DEPLACER UN ENSEMBLE D'AIMANT 60 DANS UNE POSITION EXTERNE LORSQUE LA PRESSION DU PNEUMATIQUE DIMINUE AU-DESSOUS D'UNE VALEUR DETERMINEE ET DANS UNE POSITION INTERNE LORSQUE LA PRESSION DANS LE PNEUMATIQUE AUGMENTE JUSQU'A UNE VALEUR SUPERIEURE A LA VALEUR DETERMINEE. LE SOUFFLET A UNE FORCE ELASTIQUE QUI LE POUSSE A SE DILATER, ET EST REMPLI INTERIEUREMENT D'UN GAZ SOUS UNE PRESSION DE REFERENCE ET EST EXPOSE EXTERIEUREMENT A LA PRESSION DE L'AIR DANS UN PNEUMATIQUE.
