Woodward PSG Governor

The Woodward PSG Governor is a speed control device that is used to regulate the speed of an engine. It is a mechanical device that uses a flyball governor to control the flow of fuel to the engine. The flyball governor is a centrifugal governor that uses the centrifugal force of rotating weights to control the speed of the engine. As the engine speed increases, the centrifugal force on the weights increases, causing them to move outward. This movement causes the governor to reduce the flow of fuel to the engine, which in turn slows down the engine. As the engine speed decreases, the centrifugal force on the weights decreases, causing them to move inward. This movement causes the governor to increase the flow of fuel to the engine, which in turn speeds up the engine. The Woodward PSG Governor is a reliable and accurate speed control device that is used in a wide variety of applications, including industrial, marine, and automotive applications.

The Woodward PSG Governor is a versatile device that can be used to control the speed of a wide variety of engines. It is a cost-effective solution for speed control applications and is easy to install and maintain. The Woodward PSG Governor is a valuable tool for any engine operator and can help to improve the performance and efficiency of the engine.
