Abstract (en)
[origin: US4836745A] In the case of a turbo-engine with transonically traversed stages, particularly a gas turbine with a stationary forward-guiding grid, a pressure compensating arrangement for the compensation of a pressure gradients caused by the compression waves is arranged over the circumference behind the forward-guiding grid at the hub and/or at the housing. The pressure compensating arrangement comprises especially a steadying chamber in proximity of the hub of the forward-guiding grid that interacts with a radially aligned sealing flange of the rotor disk.
