If you watch steampunk movies (i.e. Wild Wild West, League of Extraordinary Gentlemen, The Golden Compass, etc.), you might have noticed a contraption in the machines or weapons. Two metal balls that fly out when speed is increased or when pressure is applied. This small device is commonly called a Centrifugal Governor but is sometimes called a Flyball Governor. The two balls attached to the top are called Flyballs.
It was first designed by James Watt in 1764. He was worried about the inefficiency of early steam engines. The governor was used to regulate the flow of working fluid (a.k.a the steam that makes the steam engines work) supplying the prime mover.
As the speed of the prime mover increases, the governor rotates at a faster rate and this allows the two steel balls to move outwards and upwards against gravity. If the motion goes far enough, this motion causes the lever arms to pull down on a throttle valve. The rate of steam supplied is thus reduced and the speed of the prime mover is controlled, preventing over-speeding.
To put it simply, the Flyball Governor increases inlet steam when the steam engine is running too slow and vice versa. It’s an ingenious way to control the speed of steam engines automatically, so minimal human interaction is needed. (Also, it makes engines look extra cool.)
Nowadays, these have been replaced by modern governors that live inside gas-powered engines, but the importance of Flyball Governors can never go away. It’s still seen in awesome steampunk art and movies. Learn more about the centrifugal governor.
