Abstract (en)
[origin: CA2657190A1] A gas turbine is disclosed, with at least one compressor, at least one co mbustion chamber, and at least one turbine, wherein the, or each, compressor and/or the, or each, turbine has a rotor comprising guide vanes (12) enclos ed by a static housing (13), and wherein an inlet covering (15) is assigned to the housing. The gas turbine comprises at least one channel (19) in order to apply a pressure prevailing on the high pressure side of the guide vanes (12) of a rotor to a low pressure side of same, in the region of a gap (17) between the radially external ends (16) of the guide vanes (12) and the hou sing (13), and thus to eliminate a flow through the gap (17).
