A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
The devices shown are on steam engines. Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid (steam) supplying the prime mover. As the speed of the prime mover increases, the central spindle of ...
Most small engines use a governor to maintain a constant engine speed under varying loads. Some engines also have a mechanism for the user to adjust the engine speed. Rather than directly controlling the opening of the carburetor throttle, this is usually achieved by adjusting the governor, which in turn regulates the engine speed higher or lower.
Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid.
Using the clutch as quickly as possible may avoid engine damage. [1] Most small engines, such as on lawn mowers have a speed governor. As the RPM of the engine increases, the throttle plate in the carburetor is gradually closed, reducing the amount of fuel and air admitted to the engine, until the engine RPM is stable.
The overspeed governor is implemented on most marine diesel engines. [4] The governor is a safety measure that acts when the engine is approaching overspeed and will trip the engine off if the regulator governor fails. [4] It trips off the engine by cutting off fuel injection by having the centrifugal force act on levers linked to the governor ...

With the slogan “The challenger“, the HATZ 1B-series was presented in 1996, showing a number of technical highlights. In a minimum of space, all the important functional components of the engine such as decompression device, injection pump drive, oil pump with oil pump pressure regulator, valve train system for inlet and outlet valve, governor, speed control lever with governor spring and ...
