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 ...
The engine's intake system uses a gear driven supercharger and an automatic-mixture type carburetor. Power is transmitted to the propeller via a reduction gearbox. In addition to the carburetor, the engine has a speed governor, two magnetos, mechanical fuel pump, generator, and an oil pump.
Hydraulic governors use the centrifugal force but drive a medium to accomplish the same task. [4] 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 ...
The company was founded in Rockford, Illinois, in 1870 with Amos W. Woodward's invention of a non compensating mechanical waterwheel governor (U.S. patent No. 103,813). [5] [8] Thirty years later, his son Elmer patented the first successful mechanical compensating governor for hydraulic turbines (U.S. patent No. 583,527). [9]
Compression-ignition engines use mechanical governors or limiters to shut off electronic fuel injectors. A spark-ignition engine may also shut off fuel or stop the spark ignition and some just reduce the engine's power by changing the spark timing.
Electronic regulators as used in modern railway sets where the voltage is raised or lowered to control the speed of the engine Mechanical systems such as valves as used in fluid control systems. Purely mechanical pre-automotive systems included such designs as the Watt centrifugal governor whereas modern systems may have electronic fluid speed ...
