Vintage Steam Engine Governor Mechanism Diagram - Engineering History #3492523 (License: Personal Use)

The image depicts a historical centrifugal governor system, where rotating weighted balls (b) move outward under centrifugal force, actuating levers (e, f, h) to adjust the throttle valve (i) through a rigid linkage (g, k). This motion controls steam admission to the cylinder (v), maintaining consistent engine speed. The flywheel (w) provides inertia, while the central shaft (d) transmits rotation and control signals.

Commonly used in engineering textbooks, museum exhibits, and historical technology articles to illustrate James Watt’s innovation in feedback control systems; matches user intent for learning about early automation, mechanical engineering history, or steam power principles.
