ABSTRACT:
A turbodrill multistage turbine each stage of which comprises a stator and a coaxially disposed rotor. Each stator and rotor are provided with a respective spacing sleeve and a respective ring with respective flow channels and hubs. The hubs carry respective bladings disposed in the flow channels so that there are formed respective radial clearances between the ring of the stator and spacing sleeve of the rotor, and also between the ring of the rotor and spacing sleeve of the stator. At least in a number of rings the hubs are made such that there are pairs of adjacent rings in which at least a preceding (upstream) ring partially overlaps by its hub the flow channel of a subsequent (downstream) ring on the side of the radial clearance thereof.
