What is Hartung Governor? How does it work?

The Hartung Governor is spring controlled load governor categorised under the centrifugal governors. We have discussed the Hartnell governor in the previous article, which is also a spring-loaded governor which has a different working principle from this type of governor.

Hartung Governor

In this type of governor, there is no need for the load on the sleeve to increase the speed of the balls required to lift the sleeve on the spindle. Instead, we will have the springs attached to the fly balls directly with the help of the frame.

Hartung Governor is also working the same as the Hartnell governor instead of the spring load on the sleeve, spring load on the fly balls.

Construction and Working of Hartung Governor

This governor has two bell crank levers, one end of these arms are connected to the sleeve by means of rollers, and the other end, the spring balls are attached by means of mechanical spring connected by the frame. As you can see from the below schematic diagram of the Hartung Governor.

• This frame is attached to the spindle so that the frame and balls also rotate with it.
• A helical spring is compressed and provides equal radial forces on the two balls towards outwards direction.
• So that the fly balls can rotate with the spindle and compress the spring (moving the balls in outward direction) with the help of the centrifugal force when the engine is rotating at the higher speeds and control the fuel amount to decrease the fuel supply to maintain the engine speed at the mean equilibrium speed.
• Vice versa, when the engine is running at less speed than the mean nominal speed, then the fly balls will rotate closer to the spindle axis due to less centrifugal force, and increase the fuel supply.

This is how the Hartung Governor works to govern the fuel supply and regulates the mean speed of the engine when there is a variation in the load.
