Abstract
A governor device for controlling the speed of rotary devices is disclosed. The governor device is a valve operated by centrifugal force to control a pressurized fluid through the nozzles of a turbine rotor. The valve comprises a rotary chamber having an opening outwardly of a resilient valve member therein, the resilient valve member being movable by centrifugal force to control flow through said annular chamber, said annular chamber being part of the passageway of the pressurized fluid flow through said turbine rotor nozzles.
