Claims

[Scope of utility model registration request]

In a steam turbine using a pressure plate instead of a blade, the circumferential pitch of the steam flow holes of the pressure plate is equal to the circumferential pitch of the nozzle of the next stage, and the steam flow holes of the next stage are A steam turbine characterized in that a paragraph is opposed to the tip of a nozzle plate.
