{PG,1 A device for supplying fuel to an internal combustion engine comprises a shell, a tube received in the shell and a rod received in the tube with a sliding fit. A plurality of orifices in the tube at intervals along at least a portion of the length of the tube is provided. The rod is insertable in the tube to an extent sufficient to block the orifices and retractable to an extent sufficient to leave the orifices unobstructed. The number of orifices left unobstructed increases in proportion to the extent to which the rod is retracted. The rod includes means for connection to a linkage from a motor vehicle throttle for effecting axial movement of the rod. An annular space is defined between the exterior wall of the portion of the length of the tube having orifices and the portion of the length of the interior wall of the shell facing the orifices. Also provided are means defining passages for admitting liquid fuel into the annular space.
