Abstract (en)
[origin: WO2017133873A1] The invention relates to a gas turbine (1) having an axially adjustable rotor (2), comprising the following components: at least one external compressor air bleed (3) for bleeding compressor air; a control valve (4) for adjusting the amount of compressor air bled via the at least one external compressor air bleed (3); an axial thrust piston (10) that can be supplied with the compressor bleed air via a supply line (5) in such a way that a different axial compensation thrust is applied to same when the amount of compressor bleed air is adjusted; and a radial bearing (11) which cooperates with the axial thrust piston (10) for bearing purposes, and which can also be directly or indirectly supplied with the compressor bleed air via the supply line (5).
