Abstract (en)

[origin: EP0424253A1] A compressor casing consists of two, outer (2) and inner (9), envelopes forming a containment (30) closed on the upstream side by a sealing plate (29) and supplied with hot air via a downstream orifice (33). The two envelopes (39) are connected by means of connection arms (21) which are hollow and which are connected to a ventilation circuit (27, 37, 41, 42) causing cooling air to circulate inside the arms (21). <IMAGE>
