ABSTRACT:
In order to ensure correction for altitude for the carburetor used on a internal combustion engine, a control system for the pressure within the fuel bowl (8) is incorporated. This control system consists of a pressure splitter (11) that is connected, on the one hand, with the lower pressure of the venturi throat (4) in the area in which the fuel delivery line (7) opens out and, on the other hand, with the induction pressure in the area of the inlet end (10) of the air flow passage (4), said pressure splitter incorporating a pressure line (12) with two chokes (13, 14) that are connected in series, between which the fuel bowl (8) is connected to the pressure line (12). One or both of the two chokes (13, 14) can be controlled as a function of specific air density.
