Abstract
A fuel metering apparatus provides a carburetor; a fuel float control, a fuel metering assembly and a rocker arm assembly. The rocker arm is mechanically linked to and is operated by an accelerator pedal. Its position determines the size of a gap between a fuel metering tube and the metering piston, of the fuel metering assembly, to adjust a gap between the metering piston and a metering tube, which determines the precise rate of fuel flowing into the carburetor's air stream.
Claims7
A fuel metering apparatus for a carburetor, the metering apparatus comprising:
- a) a rectangular fuel metering tube providing a fuel conduction path therethrough from a fuel receiving port at one end thereof, to an elongate fuel dispensing port at the other end thereof, the fuel dispensing port centered on a convergent tip of the metering tube;
- b) a rectangular fuel metering piston positioned in line with the metering tube, the metering piston providing a V-shaped terminal end, the terminal end positioned adjacent to the convergent tip of the metering tube;
- c) a rocker arm assembly engaged with the metering piston for moving the metering piston in linear sliding motion in a journal so as to adjust a gap between the metering tube and the metering piston;
- the metering tube and the metering piston adapted for being secured within the carburetor for spraying fuel flowing within the metering tube into air flowing within the carburetor.

A fuel-air mixing apparatus comprising:
- a) a carburetor;
- b) a rectangular fuel metering tube within the carburetor, the metering tube providing a fuel conduction path therethrough from a fuel receiving port at one end thereof, to an elongate fuel dispensing port at the other end thereof, the fuel dispensing port centered on a convergent tip of the metering tube;
- c) a rectangular fuel metering piston slidingly engaged with a journal and positioned in line with the metering tube, the metering piston providing a V-shaped terminal end, the terminal end positioned adjacent to the convergent tip of the metering tube;
- d) a rocker arm assembly engaged with the metering piston for moving the metering piston in linear sliding motion in the journal so as to adjust a gap between the metering tube and the metering piston;
- the metering tube and the metering piston secured within the carburetor for spraying fuel flowing within the metering tube into air flowing within the carburetor.
