F01D 1/02 with stationary working-fluid guiding means and bladed or like rotor, (F01D1/24 takes precedence; without stationary working-fluid guiding means F01D1/18)
Introduced: September 1968
Title
Titles differ between systems:
IPC: with stationary working-fluid guiding means and bladed or like rotor
CPC: with stationary working-fluid guiding means and bladed or like rotor, (F01D1/24 takes precedence; without stationary working-fluid guiding means F01D1/18)
Full Title
Full titles differ between systems:
Non-positive-displacement machines or engines, e.g. steam turbines > with stationary working-fluid guiding means and bladed or like rotor
Non-positive-displacement machines or engines, e.g. steam turbines (wit working-fluid flows in opposite axial directions for balancing axial thrust F01D3/02; with other than pure rotation F01D23/00; turbines characterised by their use in special steam systems, cycles, or processes, regulating devices therefor F01K) > with stationary working-fluid guiding means and bladed or like rotor, (F01D1/24 takes precedence; without stationary working-fluid guiding means F01D1/18)
