An improved turbine or motor, such as a fluid or liquid driven turbine or motor or hydraulic turbine or motor including a downhole turbine for the oil/gas and geothermal industries, such as a drilling turbine or downhole drilling turbine. The turbine or motor provides a fluid passage comprising at least one portion or zone arranged to cause a drive fluid to be moved or diverted, such as at least partly radially. The turbine or motor may comprise a rotor having a rotor blade extending within the fluid passage. The turbine or motor may comprise a stator having a stator blade extending within the fluid passage. The stator (30) may comprise or define at least part of the at least one portion or zone configured or arranged to cause the fluid to be moved in or diverted from an at least part axial path to an at least part radial path or radially inward path. |
