Annular or ring-segment-shaped cavities ( 2, 7 ) which are formed in particular in multi-shell ( 11; 12, 13 ) casings of turbomachines are preferably provided with suitable means for compensating for forming temperature stratifications. According to the invention, an overflow passage ( 14 ) connects two points of the cavity to one another which are situated in different circumferential positions. Arranged in the overflow passage ( 14 ) is an ejector ( 17 ) which can be operated with a motive fluid and which serves to drive a flow through the overflow passage from an upstream end ( 15 ) to a downstream end ( 16 ).
