ABSTRACT:
The turbine rotor has about its periphery a steam track in the form of a groove. The groove is closed at its leading end by a small face and has walls which diverge in a helical pattern. The bottom and walls of the groove terminate in an outwardly sloping area which meets the closed leading end of the groove. Alternatively there may be a succession of grooves, each with a closed leading ends and diverging walls. Additionally the housing may include a stationary steam track closed at both ends with walls diverging in the opposite direction from the diverging walls of the groove in the rotor.
