Mechanical governors are devices that regulate engine speed using centrifugal force and opposing spring forces. The Hartnell governor is a spring- loaded type that uses bell-crank levers and a spring mechanism. While often depicted with helical springs, certain designs or interpretations may associate its spring system with leaf spring principles.
