Title (EN) HIGH PRESSURE ROTOR SEAL CONFIGURATION FOR SUPERCHARGER
(FR) CONFIGURATION DE JOINT D'ÉTANCHÉITÉ DE ROTOR HAUTE PRESSION POUR TURBOCOMPRESSEUR
Abstract:
(EN) A supercharger that receives and/or generates high pressure boost air and contains gear lubrication includes a housing, a rotor coupled to a rotor shaft rotatably supported in the housing, and a high pressure rotor seal disposed about the rotor shaft. The high pressure rotor seal includes a primary lip configured to contact the rotor shaft and be exposed to the gear lubrication, and at least one boost pressure blocking lip configured to contact the rotor shaft and maintain a seal against the rotor shaft when the high pressure boost air acts thereon.
(FR) L'invention concerne un turbocompresseur, qui reçoit et/ou génère de l'air de suralimentation à haute pression, et qui contient une lubrification d'engrenage, ledit turbocompresseur comprenant un boîtier, un rotor couplé à un arbre de rotor supporté de manière rotative dans le boîtier, et un joint d'étanchéité de rotor haute pression disposé autour de l'arbre de rotor. Le joint d'étanchéité de rotor haute pression comprend une lèvre primaire conçue de façon à venir en contact avec l'arbre de rotor et à être exposée à la lubrification d'engrenage, et au moins une lèvre de blocage de pression de suralimentation conçue de façon à venir en contact avec l'arbre de rotor et à maintenir un joint d'étanchéité contre l'arbre de rotor quand l'air de suralimentation à haute pression agit sur ce dernier.
