Claims6
An injection carburetor, comprising
- a. a housing having a main passage extending therethrough and a transverse bore extending across the main passage,
- b. a cylindrical control body rotatably mounted in the transverse bore and having a flow passage in the form of a cylindrical bore extending through its central portion transversely of its axis,
- c. conjugate means extending between the control body and the housing to cause the control body to move axially when it is rotated, the conjugate means consisting of a helical groove formed on the outer surface of the body and a peg fixedly mounted in the housing and having an end lying in the groove,
- d. a fuel tube mounted in the housing and extending through a suitable axial bore extending into one end of the control body, the inner end of the tube lying in the flow passage centrally thereof,
- e. a first control member extending axially through the other end of the control body into the flow passage in alignment with the end of the fuel tube, and
- f. a second control member threadedly mounted in the housing coaxially of the tube and having an end lying in the outer end of the fuel tube to permit high speed adjustment, wherein the first control member is a smaller tube than the fuel tube, so that it telescopes smoothly within it, and wherein the fuel tube has a sidewall which is provided with a T-shaped aperture that is covered and uncovered by axial movement of the first control member.
