Abstract

A speed governor for a fluid driven rotor having an inlet means for pressurized fluid to the rotor including a valve seat, a valve movable toward and away from the seat to regulate flow of fluid therethrough into the rotor, a chamber on the side of the valve opposite the seat, a supply of pressurized valve control fluid to the chamber so that increasing control fluid pressure in the chamber urges the valve toward the valve seat, and a centrifugally controlled device for increasing the pressure of valve control fluid in the chamber as a function of increasing rotational speed.
