Abstract (en)
[origin: WO03056137A1] An energy converter, particularly for use as a hydrodynamic pump, compressor, motor or turbine, comprising a stator (1) with a bore (4), where at least one helical groove (8) is formed in the wall of the bore (4), and a rotor (2) with an external surface (10), where at least one helical groove (18) is formed in the outer surface (10). The stator (1) and the rotor (2) are designed to rotate relative to each other, and at least the rotor (1) is designed to be coupled to a shaft (3) for transmission of torque. The bore (4) in the stator (1) and the external surface (10) of the rotor (2) are conical with a complementary taper.
