Abstract

L'invention concerne un mécanisme de déplacement en forme de spirale qui est facile à créer et qui a une structure dans laquelle seules des particules circulent entre deux chambres de réaction et des gaz sont moins susceptibles de se mélanger ensemble ou une structure à travers laquelle un gaz passe tout en entrant en contact avec des particules solides à une densité élevée. Le mécanisme est pourvu d'une première plaque de surface présentant une forme de type disque, d'une seconde plaque de surface présentant une forme de type disque, d'une première entrée et d'une première sortie disposées sur la première plaque de surface, d'une seconde entrée et d'une seconde sortie disposées sur la seconde plaque de surface, d'une première voie ayant une forme de spirale dans le sens des aiguilles d'une montre qui se raccorde de la première entrée à la seconde sortie et d'une seconde voie ayant une forme en spirale dans le sens inverse des aiguilles d'une montre qui se raccorde de la seconde entrée à la première sortie.
