Abstract
Disclosed herein is a rotary vaporizer that solves the problem caused by a conventional throttle valve becoming cantilevered when the throttle wire is pulled. The rotary vaporizer includes: a valve shaft; a measuring needle disposed within the valve shaft; a throttle valve having a lumen to receive the valve shaft; and a support pin having a conical distal end having a predetermined angle. The conical distal end is configured to move axially move the throttle valve by gliding on an angled surface of the throttle valve, and the angled surface is parallel to a surface of the conical distal end.
Claims14
A columnar throttle valve arranged orthogonal to the intake passage of the carburetor body, the columnar throttle valve comprising:
- a throttle hole;
- a measuring needle, and a fuel nozzle arranged on a central axis of the throttle valve and into which the measuring needle is inserted;
- a valve shaft extending from a center of an upper surface of the throttle valve, the valve shaft is configured to rotate in response to a throttle operation;
- and
- a cam mechanism for moving the throttle valve in an axial direction of the throttle valve, wherein the cam mechanism is configured to adjust the air flow rate and fuel flow rate by moving in the valve shaft and rotating the throttle valve.
