Latest Patents
Jack's latest patents include a "Carburetor and Method of Calibration" and a "Carburetor." The first patent describes a carburetor controlled by a pulse width modulated duty cycle operated solenoid. This design features a main metering rod and an idle bleed valve spring biased against a bracket carried by the solenoid armature. The armature is spring biased to a rich position against an adjustable stop and is pulled by the solenoid coil to a lean position against a portion of the solenoid coil assembly. The entire coil assembly is spring biased against a stop, which is adjusted to establish the lean position of the metering rod and bleed valve. The second patent outlines a carburetor adapted to supply a lean air-fuel mixture to the main chamber and a rich air-fuel mixture to the auxiliary chamber of a stratified charge internal combustion engine. This design includes an auxiliary induction passage formed as a cylindrical bore, which receives air from the main induction passage through a lateral inlet port. A throttle in the auxiliary induction passage is formed as a hollow cylinder conforming to the cylindrical bore and is axially reciprocable past the port to control flow.
