Abstract
A carburetor of the slide and metering rod type is characterized by the provision of a tapered metering rod for streamlining the flow of air from the inlet end of the carburetor around the metering rod to reduce turbulence and increase air velocity by compressing the air flow. The metering rod has a wedge configuration with the forward pointed edge thereof facing in the direction of the inlet end and the side walls thereof tapering outwardly and rearwardly from the forward edge.
Claims3
A carburetor, comprising
- (a) a body having an air inlet end, an air outlet end, and a throat extending therethrough from said inlet end to said outlet end;
- (b) a fuel supply tube connected with said body and having an outlet in communication with said throat;
- (c) a throttle slide member movably mounted within said body intermediate said inlet and outlet ends thereof for substantially transverse movement across said throat to vary an unblocked portion thereof;
- and
- (d) a metering rod extending downwardly into said fuel supply tube to control the supply of fuel therethrough, said metering rod being of tapered configuration in transverse cross-section and having a pointed forward edge in the direction of said inlet end and side walls which taper outwardly and rearwardly from said forward edge thereby to streamline the flow of air from said inlet end around said metering rod to reduce turbulence and increase air velocity by compressing the air flow.
