Electromagnetic fuel injector having continuous flow path

Abstract From the Canadian patent

Electromagnetic Fuel Injector, Having Continuous Flow Path Abstract, An electromagnetically operated fuel injector is constructed to provide a continuous fuel return path for removing vapors from the injector and for cooling the magnet motor. The injector is provided with a continuous liquid path between an inlet opening and a fuel return opening and an intermittent valved path between the inlet opening and the fuel discharge opening. During normal injector orientation, the continuous liquid path has a slope in the direction of flow toward the return opening which preferably is always equal to or above the horizontal. The valved path also has a slope which is preferably always equal to or …
