Mechanical device, especially based on centrifugal action of two balls, for controlling speed, etc.
In engineering, any device that controls the speed of a machine or engine, usually by regulating the intake of fuel or steam.
Scottish inventor James Watt invented the steam-engine governor in 1788. It works by means of heavy balls, which rotate on the end of linkages and move in or out because of centrifugal force according to the speed of rotation. The movement of the balls closes or opens the steam valve to the engine. When the engine speed increases too much, the balls fly out, and cause the steam valve to close, so the engine slows down. The opposite happens when the engine speed drops too much. + prikaži više
