Abstract (en)
The casing has two parts with different diameters, where the part with large diameter is provided with a mounting flange (16). A portion (25) of an annular wall extends between the mounting flange and the part with smaller diameter (23) with an annular curved form with its convexity directed toward interior of the casing. An annular web (29) extends in parallel and at distance from the portion of the wall between the flange and the part with smaller diameter. The web comprises multiple openings (34) that are regularly and circumferentially arranged.
