Patent

CA 2358953

The invention provides a diffuser assembly constructed of internal and external concentrically nested bowl-shaped shells (1, 2) for directing an outward flow of compressed air from a centrifugal compressor impeller to an axially rearward diffused annular flow. The novel diffuser assembly has two concentrically nested bowl-shaped shells (1, 2), each shell having an inner peripheral compressor impeller casing (3, 4) about a central opening, and an outer edge (5, 6). Opposing nested surfaces of the shells have an array of mating grooves (7, 8) separated by abutting seam edges (9) thus defining individual diffuser ducts extending from the compressor impeller casings (3, 4) to the outer shell edges (5, 6) when the shells are secured together. Preferably the seam edges are located on lands (10) extending laterally between adjacent grooves (7, 8) and the lands (10) extend continuously the length of the grooves (7, 8).

L'invention concerne un ensemble diffuseur constitué de coques externes paraboliques disposées de manière concentriques (1, 2) servant à diriger le flux extérieur d'air comprimé provenant d'une turbine de compresseur centrifuge, de sorte qu'un flux annulaire arrière diffusé axialement soit produit. Ledit nouveau ensemble diffuseur comporte deux coques paraboliques disposées de manière concentrique (1, 2), possédant chacune un boîtier (3, 4) de turbine de compresseur périphérique autour d'une ouverture centrale, et un bord extérieur (5, 6). Des surfaces disposées à l'opposé des coques présentent un groupe de rainures coïncidantes (7, 8) séparées par des bords de liaison adjacents (9) définissant des conduits diffuseurs séparés s'étendant des boîtiers de la turbine du compresseur (3, 4) aux bords (5, 6) de la coque extérieure, lorsque les coques sont fixées ensemble. Les bords de liaison sont situés sur des méplats (10) s'étendant latéralement entre les rainures adjacentes (7, 8) et les méplats s'étendent en continu le long des rainures (7, 8).
