Governor

Governor(ちょ lie stalk) with, machine.

steam engine engine. clock and the like there is another name.

Engine

Centrifugal governor

It is the inventor of the steam engine watt utilizes is famous.

The centrifugal governor the weight of the around axis which turns utilizes the fact that it wobbles outside due to centrifugal force. In case of the steam engine if is, it tries to operate the direction which closes the valve where wobble to outside the weight leads the steam to the cylinder. When output rises and revolution becomes fast, the weight wobbles, tries to close the valve, output holds down. When output goes down, the weight returns and tries probably to open the valve output increases. Output of the system is maintained uniformly control of this opposite direction (negative feedback) due to delicate balance. From being to operate even with when there is load in the system, just output compared to according to name it is something speed regulation.

As for similar ones gasoline engine and the like internal combustion engine? turbine engine. In gasoline engine, in place of steam valve gasolineCarburetorThe valve (of carburetor) is opened and closed.

Clock

The clock more precise speed control than such as engine of from the nature the is necessary. As for those which are used for a long time as a governor in case of the mechanical cable type clockPendulumSo it is. Speed regulation the clock making use of the isochronism of the shaking. Also those which are replaced to the vibration of the weight and the spring were invented the movement of the pendulum. As for the spring the eddying condition which usually is called the self-depreciation spring, the weight is called temperature with those of wheel condition, does the vibration which turns to left and right. This miniaturization being possible, because there is no either restriction of the installation direction like the pendulum, became the pocket watch and the way which can actualize the watch.

Main current of today is the quartz clock, the above-mentioned mechanical governor in only the relatively large amount clock is designed in such a way that it is used.

Music box

music box, at the tempo which is decided, but as for the precision like the clock there is no necessity. In the small-sized music box which today is seen generally for speed regulation the car where the feather is attached (the air governor) has been attached, it has become the device which holds down revolution with aerodynamic drag.
