ABSTRACT:
An internal combustion engine overspeed protection system utilizes a spring-actuated expandable overspeed link in the fuel control linkage to shut off fuel independently of governor or throttle action. The link is normally latched in a contracted condition and positioned in the fuel linkage between a manual fuel lever and the fuel cranks for the respective cylinders of the engine. An automatically resetable hydraulic actuating device unlatches the link in high speed response to an engine overspeed condition. A spring coupling in the fuel linkage permits relatching of the overspeed link by manipulation of the fuel lever.
