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 ...
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 higher cost of turbines and the associated gears or generator/motor sets is offset by lower maintenance requirements and the smaller size of a turbine in comparison with a reciprocating engine of equal power, although the fuel costs are higher than those of a diesel engine because steam turbines have lower thermal efficiency. To reduce fuel ...

The firm secured the contract to make engines for the Dayton motorised bicycle made by Charles Day Manufacturing Co in Shoreditch, London, which was until then purely a bicycle manufacturer. [6] This went on sale in late 1913. The engine has a one-piece cylinder and head with a rear-facing spark plug, and was of 162 cc, rated at 1.5 HP.
As the load on mill engines and similar uses could vary, closed-loop control such as the engine speed-based centrifugal governor was also needed. [20] The cataract was thus not used on rotative engines, not even where single-acting Cornish winding engines were still used in Cornwall. [21]
The solution developed for high-speed steam engines was the "automatic" governor. Rather than controlling the flow rate of steam, it controlled the timing or 'cut-off' of the inlet valves. [6] [7] This governor was interspersed between the crankshaft and the eccentric driving the valve gear. It was often made as part of the engine's flywheel.
In larger steam turbines an oil operated servo mechanism is used in order to enhance the lever sensitivity. The use of a relay system magnifies the small deflections of the lever connected to the governor sleeve. [2] The differential lever is connected at both the ends to the governor sleeve and the throttle valve spindle respectively.
