Abstract
Abstract A rotary device with a speed governor and having a centrifugally radially expandable rotor with a drive surface acted upon by pressurized fluid, either gas or liquid, for this rotating the rotor and a fluid passage in the rotor to this surface including an inlet for the fluid and valve means in the rotor fluid passage movable to restrict flow of the fluid to the surface upon centrifugal expansion of the rotor in order to govern the speed of rotation. The disclosure is also directed to a rotor having such a drive surface and centrifugally operated valve means for restricting flow of the fluid in the rotor to the surface to govern the speed of rotation. The disclosure is further directed to a hollow flexible rotor expandable radially under centrifugal forces to move the sides of the rotor toward each other during this centrifugal expansion and a fluid valve in the rotor that is moved toward closed position by the centrifugal expansion to govern the speed of the rotor.
