Fuel bowl and method of feeding fuel

摘要

A fuel bowl for a carburetor has no valves and is configured for continuous flow of fuel through the bowl. The fuel bowl can be constructed to constrain the constantly flowing fuel within a compartment of the bowl to maintain fuel level in the bowl sufficient to meet the carburetor demand under circumstances of high fuel demand and/or high g-forces. A method of continuously circulating fuel through the fuel bowl facilitates fuel level maintenance over a range of performance requirements.

主权项

1. A fuel bowl for holding liquid fuel to be fed into a carburetor for an internal combustion engine, the fuel bowl comprising a body having an internal cavity and a back wall partially defining the internal cavity configured for interfacing with a meter block of the carburetor, the back wall having a thickness, a bottom end, a top end, and a height extending between the bottom end and the top end, a fuel inlet configured to receive fuel from a fuel tank into the cavity, a recirculation outlet configured to pass fuel from the internal cavity back to the fuel tank and a fuel supply outlet configured for mating with a carburetor fuel inlet for passing liquid fuel from the cavity to the carburetor, the fuel supply outlet extending from an opening facing the internal cavity through the thickness of the back wall, said opening being spaced apart between the top end and the bottom end of the back wall, the body being free of valving whereby fuel can be circulated continuously through the cavity to maintain a fuel level in the internal cavity above said opening of the fuel supply outlet.
