To provide a carburetor in which the fuel/air proportion in the mixture supplied is not materially affected by ambient atmospheric pressure, without introducing problems during engine idling due to the introduction of excessive fuel vapor into the carburetor induction passage, a valve controlled in common with the engine throttle valve which, when the said throttle valve is open connects the fuel chamber to a controlled source of suction, is moved when the throttle valve is closed to connect said fuel chamber to the ambient atmosphere. |
