Abstract (en)
[origin: WO2012097798A1] Intermediate housing (14), in particular of turbines (11, 13) of a gas engine, having a radially inner bounding wall (23) and having a radially outer bounding wall (24, 24'), having a crossflow channel (33) which is formed by the bounding walls (23, 24, 24') and in which at least one supporting rib (15) is positioned which has a front edge (16), a rear edge (17) and side walls (18) which extend between the front edge (16) and the rear edge (17) and guide a gas flow which flows through the crossflow channel (33), wherein the radially outer bounding wall (24) has a contour which changes in the circumferential direction, at least in a section upstream of the supporting rib (15).
