This invention discloses improvements in carburetors for internal combustion engines, so as to allow a change in the carburetor throat (venturi choke) in proportion to the admission of the gasoline-air mixture, with no change involved in the jet spray nozzle. In this manner, carburetors can be adapted to an extensive power range of gas engines. This variation is obtained through two cylindrical orthogonal sections, oppositely disposed at their curved sections and are centrally recessed, in such a manner that, while rotating or pivoting one against the other they will form a chamber with a central circular passage of a variable diameter, the largest being made up by the opposition of two of the edges and the smallest by the opposition of the two other edges. |
