Title: Water turbine or water pump

Abstract: A water turbine or pump having a rotor (1) and a stator (2). The leading edges (13) and the trailing edges (14) at least of the rotor blades (6) form a bend (15) projecting in opposite relationship to the flow direction (12). That causes a flow force resulting in a self-cleaning effect being applied to impurities which are deposited at the leading edges (13). However the adjustment design providing for adjustability of the rotor blades remains substantially unchanged.
