Abstract
A carburetor float bowl. The float bowl includes a float adapted to be flotationally supported by liquid fuel in the float bowl over a predetermined range of the level of fuel therein. A fuel inlet is adapted to direct fuel along a line toward the floor of the float bowl. The float bowl further includes a “fuel chute” having a ramping surface, a portion of which is intersected by said line at a point thereon. The ramping surface is disposed to provide a ramp angle at said point with respect to the floor that is substantially greater than 90 degrees and substantially less than 180 degrees.
Claims11
A carburetor float bowl having a floor and adapted for containing liquid fuel, comprising:
- a float adapted for flotation in the fuel in the float bowl over a predetermined range of the level of the fuel;
- a fuel inlet adapted to receive the fuel under pressure, said fuel inlet comprising a valve including a valve closing element coupled to said float and adapted to substantially stop the flow of fuel when said float rises to a predetermined maximum level of said range, said fuel inlet adapted to direct fuel along a line toward the floor of the float bowl;
- and
- a fuel chute having a ramping surface, a portion of which is intersected by said line at a point thereon, said ramping surface providing a ramp angle at said point with respect to the floor that is substantially greater than 90 degrees and substantially less than 180 degrees, wherein said ramping surface has an end terminating substantially at the floor.
