How does a Prop Governor work?

Hi,

I was wondering if anyone can explain exactly how a prop governor
works for a constant speed prop system? All I know is that the engine
Oil pushes a piston in the prop hub that twists the prop to the
appropriate angle.

Thanks,
Felix

most governors work the same way... rotation moves a set of weights
that move a valve that lets oil through.

in case of a single engine plane prop, the governor lets more oil through
as the RPMS go up to rotate the blades and increase pitch.

Go to http://www.avweb.com/news/columns/182146-1.html and take a look
at the Engine-Related Columns (scroll down some they are on the right hand
side). Esp these four:

Pelican's Perch #15: Manifold Pressure Sucks!
Pelican's Perch #16: Those Marvelous Props
Pelican's Perch #18: Mixture Magic
Pelican's Perch #19: Putting It All Together

They pretty much cover the subject of how engines, the throttle/MP, props,
and mixture work. I found them very helpful when I was a student.

Good governor description, the propeller designs shown are kind of
dated. Most modern props use either a spring assembly or a air-charged
piston/spring combination to oppose the "governed" oil pressure
deliverd to the propeller.

The other links mentioned in this thread will tell you the whole story.
If you want a closeup of what the weights look like and a brief
explanation of how they fit into the grand scheme, take a look at ours...
