  • Rotary tool
    Patent number: 7223069
    Abstract: A rotary device having an inlet adapter for connecting the device to a pressurized fluid source, a turbine rotor, and an input passage. The input passage provides fluid communication between the input adapter and the turbine rotor, has a first end proximate the inlet adapter and an opening downstream from the first end, and has a generally constant cross sectional area between the first end and the opening.

  • High torque dual chamber turbine rotor for hand held or spindle mounted pneumatic tool
    Patent number: 7077732
    Abstract: A high torque turbine rotor for a lightweight hand held tool for grinding and polishing having a rotor that includes two separate high pressure air chambers separated by a common housing wall, each air chamber having peripheral air expelling nozzles in a tangential direction to the rotor periphery. The rotor housing is lightweight and increases torque without generally increasing the overall size and weight of the tool housing.
