Device for controlling the admission of fuel into an internal combustion engine

Claim 1

IN A FUEL CONTROL DEVICE FOR AN INTERNAL COMBUSTION ENGINE HAVING AN INTAKE MANIFOLD AND A FUEL MIXTURE PASSAGEWAY OPERATIVELY COMMUNICATING THEREWITH AND WITH A CARBURETOR HAVING A FLOAT BOWL WITH AN AIR CHAMBER THEREIN, THE COMBINATION OF CONDUIT MEANS COMMUNICATING BETWEEN SAID INTAKE MANIFOLD AND SAID FLOAT BOWL AIR CHAMBER, A VALVE MEMBER IN SAID CONDUIT MEANS MOVABLE BETWEEN OPEN AND CLOSING POSITIONS RELATIVE THERETO, AIR VENT MEANS IN SAID CONDUIT MEANS POSITIONED BETWEEN SAID VALVE MEMBER AND SAID AIR CHAMBER AND IN CONSTANT COMMUNICATION WITH SAID AIR CHAMBER, AN ELECTRICAL GENERATOR CONNECTED TO SAID ENGINE, WHEREBY THE SPEED OF THE ENGINE WILL CONTROL THE OPERATIVE SPEED OF THE GENERATOR, ELECTRO-MECHANICAL MEANS COMPRISING A CORE AND TWO OPPOSING CONDUCTING COILS OPERATIVELY DISPOSED THEREABOUT, THE FIRST BEING A MAGNETIZING COIL AND THE SECOND A DEMAGNETIZING COIL, AN ARMATURE ARM IN OPERATIVE RELATION TO SAID CORE AND MOVABLE BETWEEN TWO RESPECTIVE LIMITING POSITIONS WHEN SAID CORE IS OPERATIVELY MAGNETIZED AND OPERATIVELY DEMAGNETIZED, AN ELECTRICAL CIRCUIT CONNECTING SAID GENERATOR TO SAID FIRST COIL, ANOTHER ELECTRICAL CIRCUIT CONNECTING SAID GENERATOR TO SAID SECOND COIL, SWITCH MEANS IN SAID LATTER CIRCUIT, ACTUATING MEANS FOR SAID SWITCH MEANS, VALVE-ACTUATING MEANS OPERATIVELY CONNECTED TO SAID VALVE MEMBER AND OPERATIVELY RESPONSIVE TO SAID ARMATURE ARM IN ONE OF ITS SAID POSITIONS, WHEREBY SAID VALVE-ACTUATING MEANS WILL ACTUATE SAID VALVE MEMBER WHEN SAID ARM IS OPERATIVELY ACTUATED BY SAID ELECTROMECHANICAL MEANS, THE ELECTRICAL CHARACTERISTICS OF SAID RESPECTIVE COILS AND THEIR SAID RESPECTIVE CIRCUITS BEING SUCH THAT IN RESPONSE TO GENERATOR VOLTAGE ABOVE A PREDETERMINED CRITICAL MAGNITUDE SAID CORE WILL BE MAGNETIZED TO A DEGREE SUFFICIENT FOR MAGNETICALLY HOLDING SAID ARM, AND IN RESPONSE TO GENERATOR VOLTAGE BELOW SAID CRITICAL MAGNITUDE SAID CORE WILL BE OPERATIVELY DEMAGNETIZED, SAID ELECTRICAL CHARACTERISTICS BEING ALSO SUCH THAT AT THE TIME OF THE OPERATIVE CLOSING OF SAID SWITCH MEANS THE CONSEQUENT ENERGIZATION OF SAID SECOND COIL WILL OCCUR WHEN THE GENERATOR VOLTAGE IS AT A HIGHER MAGNITUDE THAN SAID CRITICAL MAGNITUDE, SAID GENERATOR BEING OPERABLE AT A RANGE OF SPEEDS FOR PRODUCING VOLTAGE OF MAGNITUDES RANGING FROM BELOW TO ABOVE SAID CRITICAL MAGNITUDE.
