Abstract
A regulatable dental turbine includes an actuator arrangement which is provided for regulating the speed by varying the amount of an essentially constant volume stream of drive fluid striking a turbine wheel of the dental turbine. The change of the direction based on the actuator arrangement bypasses a portion of the volume hitting the blades of the dental turbine. The actuator arrangement operates in a speed-dependent fashion based on the flow deflected by the blades of the wheel on an impact surface.
