Apparatus for the controlling of the supply of fuel and air to internal combustion engines

Claim 1

AN APPARATUS FOR CONTROLLING THE SUPPLY OF FUEL AND AIR TO AN INTERNAL COMBUSTION ENGINE HAVING AN AIR INTAKE MEMBER, AN AIR INTAKE THROTTLE VALVE LOCATED WITHIN SAID AIR INTAKE MEMBER AND CONTROLLING THE FLOW OF AIR THROUGH SAID INTAKE MEMBER, AND A DRIVER-OPERATED MEMBER, SAID APPARATUS COMPRISING A FUEL CONTAINER, A PUMP FOR RECEIVING FUEL FROM SAID CONTAINER, SAID PUMP HAVING A MAXIMUM CAPACITY EXCEEDING THE MAXIMUM FUEL REQUIREMENTS OF SAID ENGINE, A PUMP OUTPUT MEANS CONNECTED TO SAID PUMP AND CONTAINING FUEL FROM THE PUMP, VALVE MEANS CONNECTED WITH THE PUMP OUTPUT MEANS AND OPERATIVELY CONNECTED TO THE DRIVER-OPERATED MEMBER, SAID VALVE MEANS CONTROLLING EXHAUST OF THE FUEL FROM THE PUMP OUTPUT MEANS TO SAID FUEL CONTAINER IN DEPENDENCE UPON THE MOVEMENTS OF SAID DRIVER-OPERATED MEMBER, A CONTROL CHAMBER HAVING A MOVABLE CONTROL MEMBER DISPOSED THEREIN, SAID CONTROL CHAMBER BEING COUPLED TO SAID PUMP OUTPUT MEANS SO THAT THE PRESSURE OF THE FUEL IN SAID PUMP OUTPUT MEANS IS APPLIED TO SAID MOVABLE CONTROL MEMBER TO DISPLACE THE LATTER IN ONE DIRECTION OF MOVEMENT THEREOF, CONNECTING MEANS ACUTUATED BY SAID MOVABLE CONTROL MEMBER AND CONNECTED WITH THE AIR INTAKE THROTTLE VALVE SO AS TO OPEN THE LATTER WITH INCREASING FUEL PRESSURE, AIR CONTROLLED MEANS FOR DERIVING A FORDE PROPORTIONAL TO THE RATE OF FLOW OF AIR IN THE ENGINE AIR INTAKE MEMBER, MEANS FOR APPLYING SAID FORCE TO SAID MOVABLE CONTROL MEMBER IN OPPOSITION TO THE FUEL PRESSURE THEREON SO AS TO MAINTAIN SAID MOVABLE CONTROL MEMBER IN EQUILIBRIUM WHEN THE FUEL PRESSURE IS BALANCED BY SAID FORCE, AND AN EXHAUST OPENING LEADING FROM SAID CONTROL CHAMBER TO SAID FUEL CONTAINER, SAID EXHAUST OPENING BEING CONTROLLED BY SAID MOVALBE CONTROL MEMBER WHICH OPENS SAID EXHAUST OPENING AT SUBSTANTIALLY FULL THROTTLE.

Claim 2

AN APPARATUS FOR CONTROLLING THE SUPPLY OF FUEL AND AIR TO AN INTERNAL COMBUSTION ENGINE HAVING AN AIR INTAKE MEMBER, AN AIR INTAKE THROTTLE VALVE LOCATED WITHIN SAID AIR INTAKE MEMBER AND CONTROLLING THE FLOW OF AIR THROUGH SAID INTAKE MEMBER, AND A DRIVER-OPERATED MEMBER, SAID APPARATUS COMPRISING A FUEL CONTAINER, A PUMP FOR RECEIVING FUEL FROM SAID CONTAINER, SAID PUMP HAVING A MAXIMUM CAPACITY EXCEEDING THE MAXIMUM FUEL REQUIREMENTS OF SAID ENGINE, A PUMP OUTPUT MEANS CONNECTED TO SAID PUMP AND CONTAINING FUEL FROM THE PUMP, VALVE MEANS CONNECTED WITH THE PUMP OUTPUT MEANS AND OPERATIVELY CONNECTED TO THE DRIVER-OPERATED MEMBER, SAID VALVE MEANS CONTROLLING EXHAUST OF THE FUEL FROM THE PUMP OUTPUT MEANS TO SAID FUEL CONTAINER IN DEPENDENCE UPON THE MOVEMENTS OF SAID DRIVER-OPERATED MEMBER, A CONTROL CHAMBER HAVING A MOVABLE CONTROL MEMBER DISPOSED THEREIN, SAID CONTROL CHAMBER BEING COUPLED TO SAID PUMP OUTPUT MEANS SO THAT THE PRESSURE OF THE FUEL IN SAID PUMP OUTPUT MEANS IS APPLIED TO SAID MOVABLE CONTROL MEMBER TO DISPLACE THE LATTER IN ONE DIRECTION OF MOVEMENT THEREOF, CONNECTING MEANS ACUTUATED BY SAID MOVABLE CONTROL MEMBER AND CONNECTED WITH THE AIR INTAKE THROTTLE VALVE SO AS TO OPEN THE LATTER WITH INCREASING FUEL PRESSURE, AIR CONTROLLED MEANS FOR DERIVING A FORDE PROPORTIONAL TO THE RATE OF FLOW OF AIR IN THE ENGINE AIR INTAKE MEMBER, MEANS FOR APPLYING SAID FORCE TO SAID MOVABLE CONTROL MEMBER IN OPPOSITION TO THE FUEL PRESSURE THEREON SO AS TO MAINTAIN SAID MOVABLE CONTROL MEMBER IN EQUILIBRIUM WHEN THE FUEL PRESSURE IS BALANCED BY SAID FORCE, AND AN EXHAUST OPENING LEADING FROM SAID CONTROL CHAMBER TO SAID FUEL CONTAINER, SAID EXHAUST OPENING BEING CONTROLLED BY SAID MOVALBE CONTROL MEMBER WHICH OPENS SAID EXHAUST OPENING AT SUBSTANTIALLY FULL THROTTLE.
