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) > having two or more stages subjected to working-fluid flow without essential intermediate pressure change, i.e. with velocity stages (F01D1/12 takes precedence)
