A device that keeps the propeller speed constant irrespective of the forward speed and power. The governor is usually centrifugal and keeps the shuttle valve oscillating about the null-position feeding oil to change the propeller pitch and thus increase or decrease the RPM.

The genius of the constant-speed prop is that it does exactly what its name implies: turns at a constant rpm set by the pilot, who really is adjusting the propeller governor. The typical prop governor is a bolt-on device used to increase the engine oil's pressure and meter its flow into the propeller hub to hydraulically rotate the blades and change their angle of attack.
The diagrams in the sidebar on the opposite page show how a typical non-feathering hydraulic prop uses engine oil from the propeller governor to change the blades' position when increasing, decreasing or maintaining a pitch setting.
