ABSTRACT:
A pressure ratio valve is installed in an internal combustion engine having a pressurized air supply and an air actuatable throttle control means for limiting the engine RPM in response to a pneumatic control signal. The pressure ratio valve continuously senses both the engine oil pressure and the pressure of the engine compressed air system and generates the pneumatic control signal in response thereto. When the oil pressure-air pressure ratio decreases below a predetermined magnitude, an unsafe engine oil pressure condition is indicated and the pressure ratio valve generates a pneumatic control signal which causes the throttle control means to limit the engine RPM to a safe level.
