Abstract

Procédé et appareil pour la répartition rapide d'un premier gaz dans une chambre contenant un mélange de ce premier gaz et d'un second gaz, et notamment pour la pressurisation de corps de balles de tennis avec un gaz à faible pouvoir pénétrant qui ne diffuse que très lentement dans l'air. L'invention permet d'accélérer beaucoup la répartition du gaz peu pénétrant dans tout le moule grâce à un procédé et à un appareil assurant, sous l'effet d'une pompe 22, la circulation du mélange gazeux à travers le moule 2 et un conduit 16 relié au moule en circuit fermé. Application à la fabrication de balles de tennis capables de maintenir longtemps la même pression au mélange gazeux qu'elles renferment
