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 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 ...
Adjustments in power output for a particular primer mover and generator combination are made by slowly raising the droop curve by increasing the spring pressure on a centrifugal governor or by an engine control unit adjustment, or the analogous operation for an electronic speed governor. All units to be connected to a grid should have the same ...
Operation in a single engine reciprocating aircraft is as follows: Engine oil is pumped through the propeller shaft by the governor to push on a piston that drives the mechanism to change pitch. The flow of oil and the pitch are controlled by a governor, consisting of a gear type pump speeder spring, flyweights, and a pilot valve. The gear type ...
In engines with fuel injection system, the lever is typically referred to as power lever and controls the amount of fuel that is injected into the cylinders. Propeller control or Governor - Adjusts the propeller blade pitch and regulates the engine load as necessary to maintain the set revolutions per minute (RPM). See the section on propeller ...
The overspeed governor is implemented on most marine diesel engines. [4] The governor is a safety measure that acts when the engine is approaching overspeed and will trip the engine off if the regulator governor fails. [4] It trips off the engine by cutting off fuel injection by having the centrifugal force act on levers linked to the governor ...
Helicopter rotors are designed to operate at a specific rotational speed. The throttle controls the power of the engine, which is connected to the rotor by a transmission. The throttle setting must maintain enough engine power to keep the rotor speed within the limits where the rotor produces enough lift for flight.
For an aircraft engine, changes in airspeed or altitude cause changes in air speed and density through the engine, which would then have to be manually adjusted for by the pilot. A fuel control unit attempts to solve those problems by acting as an intermediary between the operator's controls and the fuel valve.
