| 摘要 |
This invention relates to an improved turbine or motor, such as a fluid or liquid driven turbine or motor or hydra u lic turbine or motor. The invention also relates to an improved downhole turbine which may find use in the oil/gas and geothermal industries, such as a drilling turbine or downhole drilling turbine. The turbine or motor (5) 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 (5) may comprise a rotor (25) comprising at least one rotor blade (15) extending within the fluid passage. The turbine or motor may comprise a stator (30) comprising at least one stator blade (20) 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. |
