ABSTRACT:
A carburetor has a choke device formed of two planar quadrangular choke flaps situated side-by-side in a cross-sectionally quadrangular flow passage of an engine intake manifold. The pivotal supports for the choke flaps are held in recesses of the manifold wall and define a pivotal axis that lies in an edge zone of the choke flaps that is immediately adjacent the manifold wall. The choke flaps further have cooperating edge zones that together define the cross section of the flow passage as a function of pressure conditions in the intake manifold. In the fully open position, the choke flaps are in a face-to-face engagement with opposite wall portions of the intake manifold.
