ABSTRACT:
A system (10) for sealing and pressurization for the support cushion (24) of a gas turbine (20), wherein the gas turbine (20) is provided with a compressor (21), with which there is associated an inner barrel (23), and the support cushion (24) is in turn provided with seals (38, 39) relative to the axis of the compressor (21), and has at least one pipe (33) for the venting discharge. The air is fed into the inner barrel (23), using the venting piping (33) of the support cushion (24), such as to create a flow of air, which starts from an intermediate stage of the compressor (21), and goes towards the inner barrel (23).
