Pressurised gas turbine, especially for a motor vehicle, has inner and outer rotors with rolling bodies and gas injection nozzles

摘要

The turbine, operated by gas under pressure, consists of inner (2) and outer (3) rotors with races (7, 17) for rolling bodies (4). It has seals (45) for the space between the rotors, at least one nozzle (10, 29) for injecting pressurised gas into the space, and at least one air outlet nozzle (12), the injection nozzles being positioned to direct the gas at tangent to the rotor and towards the rolling bodies. The turbine has a transmission system with a planetary reduction gear train (25) comprising an outer crown wheel (20) turning with the outer rotor, a sun wheel (24) turning with the inner one, and satellite gears (27) between them connected to a fixed carrier (26).
