n: on a mechanical engine governor, one of usually two small metal weights that spin as the engine runs. When the engine speeds up, centrifugal force on the spinning flyweights increases, which causes a spring to compress and slow the engine down. Conversely, when the engine slows down, centrifugal force on the flyweights decreases which causes the spring to expand and speed the engine up.

n: a speed-control device on an engine. Mechanical governors consist of flyweights, springs, and mechanical connections to the engines speed control. Compare electrically-actuated governor;hydraulic governor. See governor.

n: a small spring inside an engine governor that counteracts the force of flyweights in the governor. The speeder spring moves down on a sleeve in the governor to increase the fuel supply to the engine, at the same time, the flyweights move the sleeve up to decrease the fuel supply. Since the flyweights spin at a speed determined by the engines speed. if engine speed drops, the speeder spring moves down to speed the engine up. Seeftyweight, governor.
