Abstract

L'invention concerne un dispositif de gonflage comprenant un corps de valve et une vessie compressible. Le corps de valve comporte une entrée et une sortie unidirectionnelle. La vessie est fixée au corps de valve et communique avec la sortie et l'entrée par l'intermédiaire de passages situés dans le corps de valve. De l'air est aspiré dans la vessie via l'entrée par extension de la vessie, et évacué depuis la sortie unidirectionnelle par compression de la vessie. Ce dispositif de gonflage peut être mis en oeuvre sans recours à un autre dispositif de gonflage ou compresseur motorisé, et peut aspirer l'air depuis l'extérieur par compression dela vessie, puis charger l'air dans une cavité intérieure d'un produit de gonflage. Le dispositif de gonflage peut être facilement combiné au produit de gonflage et se caractérise avantageusement par la simplicité de sa structure et par sa facilité d'utilisation.
