Abstract

La présente invention se rapporte à un procédé permettant de faire fonctionner un palier à gaz, ledit procédé consistant à mettre sous pression une source de pression du palier à gaz avec un gaz sous pression. Le procédé consiste également à faire circuler le gaz à travers une pluralité d'éléments de flexion en communication fluidique avec la source de pression et à former une partie palier caractérisée par une pression égale à une première pression hydrostatique et disposée entre chacun élément de flexion et un chemin de roulement. Le procédé consiste en outre à augmenter la pression dans la partie palier à une seconde pression hydrostatique supérieure à la première pression hydrostatique, à déformer la pluralité d'éléments de flexion et à rétablir la pression dans la partie palier à la première pression hydrostatique.
