Governor Load: Watt Governor Design

The Watt governor is characterized by its simplicity and does not incorporate any additional central load attached to the sleeve. The sleeve's position is determined solely by the centrifugal forces acting on the rotating balls and the geometry of the linkage mechanism.

Comparison with Other Governors

In contrast:

• The Porter governor adds a significant central dead weight to the sleeve. This weight increases the effort required to raise or lower the sleeve, making the governor more sensitive to speed changes.
• The Proell governor also utilizes a central load, similar in principle to the Porter governor, although its specific construction differs.

Therefore, the Watt governor is the type that lacks a central load attached to its sleeves.
