PRESSURIZED GAS TURBINE SYSTEM

摘要

The invention concerns a pressurized gas turbine system comprising an inner rotor (2), an outer rotor (3) provided with rolling elements (40) arranged between the inner and outer rotors, sealing members (45) for hermetically sealing the space included between the inner and outer rotors, and at least one pressurized gas injecting nozzle (10, 29) arranged on one rotor and emerging into the space included between the inner (2) and outer (3) rotors. The sealing members (45) comprise each a part in the shape of a truncated ring extending between the rolling elements (40) and provided with two mutually opposed concave end surfaces (45-a, 45-b) against which adjacent rolling elements (40) are respectively urged to press. Additionally, each sealing member is provided externally with a groove (45-c) extending between the adjacent rolling elements to guide the gas delivered by the injection nozzle towards on of said rolling elements.
