ABSTRACT:
An idle speed-limiting speed engine governor utilizes a friction damped air piston as the sole speed setting means which actively opposes the speed responsive flyweights in a particular range of engine speed operation, the governor limiting speed being controllable by adjusting the air pressure acting against the piston. A minimum droop governor characteristic results with hysteresis limited by minimum friction damping of the piston. A multi-condition air pressure control system is disclosed which is capable of providing various operational modes for the air controlled limiting speed governor.
