FIELD: sealing-up gas turbine and building-up increased pressure for gas turbine support shock absorber.
SUBSTANCE: gas turbine is provided with compressor which is connected with inner cavity and support shock absorber is provided in its turn with seals relative to compressor axle; it is provided with at least one air-exchange tube. Air is fed to inner cavity by means of venting tube of support shock absorber for forming the flow beginning with compressor intermediate stage towards inner cavity. Such construction of system makes it possible to perform adjustment oriented for consumer.
EFFECT: continuous operation of system without stopping the plant.
