Beschreibung
Zusammenfassung:	The invention relates to a device (9) for cooling a turbine casing (7) for a turbomachine, such as for example an aircraft turbojet engine, extending around an axis (X) and comprising air-distribution means configured to take in air and convey it to the casing, characterized in that the air-distribution means comprising at least a first ramp (20a, 20b) and a second ramp (20a, 20b) extending circumferentially about the axis (X) respectively on a first circumferential portion and on a second circumferential portion which are different from each other, each ramp (20a, 20b) comprising air ejection orifices intended to be directed towards the casing in order to cool it, characterized in that it comprises adjustment means (23) capable of adjusting the flow rate of air ejected at the level of the first ramp (20a, 20b) with respect to the flow rate of air ejected at the level of the second ramp (20a, 20b).
