A contrivance applied to steam engines, water wheels, and other machinery, to maintain nearly uniform speed when the resistances and motive force are variable.
1. A device that controls another device, usually on the basis of speed or rpm. 2. A speed-sensitive mechanical assembly in the automatic transmission driven by the output shaft, to supply primary control of when shifting is to occur.
A device which limits or regulates the speed of an engine in revolutions per minute; in general, gasoline engine governors control speed by restricting intake air, while Diesel governors limit amount of fuel injected. Specific types of governors most generally used and engine applications are as follow: Velocity Type (Gas) Governor, Vacuum-Centrifugal Type (Gas) Governor, Mechanical-Centrifugal Type (Gas)Governor, Hydra-Mechanical Type (Diesel) Governor, Mechanical Flyball (Diesel) Governor, Mechanical Flyweight (Diesel) Governor, and Centrifugal-Mechanical (Diesel) Governor.
