Abstract

LA CHAMBRE D'UN PALIER EST POURVUE D'ORIFICES DE DRAINAGE SUR LES DEUX COTES DU PALIER, CE QUI EVITE DES ACCUMULATIONS D'HUILE RISQUANT D'ASPERGER LES JOINTS DE LA CHAMBRE. CETTE CHAMBRE COMPREND TROIS COMPARTIMENTS A, B, C ET ELLE EST PRESSURISEE PAR L'AIR QUI PASSE PAR LES JOINTS EN 9, 10. UN CONDUIT DE DRAINAGE PRINCIPAL 37 DRAINE LE COMPARTIMENT PRINCIPAL A DU PALIER, PAR L'INTERMEDIAIRE D'UNE POMPE D'EVACUATION QUI VA AU RESERVOIR D'HUILE. EN FONCTIONNEMENT NORMAL, DES PASSAGES 47 ET 49 DRAINENT L'HUILE DES COMPARTIMENTS LATERAUX B, C VERS LE COMPARTIMENT CENTRAL A. QUAND L'ORIFICE DE DRAINAGE PRINCIPAL 39 NE FONCTIONNE PLUS EN RAISON DE MONTEES SOUDAINES DE L'HUILE VERS LES EXTREMITES DE LA CHAMBRE, L'HUILE PASSE PAR DES CONDUITS DE DRAINAGE AUXILIAIRES 55 ET REVIENT AU RESERVOIR GRACE A LA PRESSION REGNANT DANS LA CHAMBRE. DES CHICANES 71, 73 EMPECHENT L'HUILE D'ETRE PROJETEE SUR LES ORIFICES DE DRAINAGE AUXILIAIRES 51 A UNE VITESSE EXCESSIVE.
