发明名称 ROTARY THROTTLE VALVE CARBURETOR
摘要 PROBLEM TO BE SOLVED: To provide a mechanism for interlocking a needle with the rotation of a throttle valve and fine adjusting the vertical direction with a simple structure, in a rotary throttle valve-type carburetor in which a throttle valve chamber is provided perpendicular to an intake passage perforating through a carburetor main body, a throttle valve having a throttle hole facing the intake passage is rotatably arranged, and a fuel control means for controlling the fuel injection amount by the rotation of a needle is provided on the overlapped part of the fuel nozzle and the needle. SOLUTION: An adjusting screw 18 is screwed to the upper part of a throttle valve 6, so as to deviate from the rotational center of the throttle valve, and an adjusting screw 18 is engaged in the deviated position of the upper surface of a needle head part 16. Therefore, the rotation of a needle 15 is prevented and interlocked with the rotation of the throttle valve, and the needle 15 can be vertically and finely adjusted by the rotation of the adjusting screw 18.
