Abstract

LA PRESENTE INVENTION CONCERNE LES PALIERS LUBRIFIES PAR UN GAZ, ET PLUS PARTICULIEREMENT ELLE CONCERNE L'ELIMINATION EN DEHORS DU PALIER PROPREMENT DIT DES AGENTS DE CONTAMINATION RENFERMES PAR LE GAZ. D'APRES L'INVENTION, LE GAZ EST SOUMIS A UNE EXPANSION ESSENTIELLEMENT ADIABATIQUE ACCOMPAGNEE D'UNE CHUTE DE TEMPERATURE DANS UNE REGION DE L'APPAREIL OU LA CONDENSATION DES AGENTS DE CONTAMINATION NE PEUT PAS AVOIR D'EFFETS NUISIBLES. DANS CE BUT, ON AMENAGE UN COMPARTIMENT D'EXPANSION RENFERMANT UN ETRANGLEMENT QUI ENTRAINE UNE NETTE CHUTE DE PRESSION ACCOMPAGNEE D'UNE CHUTE DE TEMPERATURE EN RAPPORT, A TEL POINT QUE LA CONDENSATION DES AGENTS DE CONTAMINATION VAPORISES EST PROVOQUEE. LA PRESENTE INVENTION PEUT SERVIR DANS LES PALIERS A LUBRIFICATION A GAZ.
