ABSTRACT:
Carburetor for an internal combustion engine showing a suction port (1) which is in connection with the combustion chamber of the motor and which is fed with liquid fuel via a nozzle (3) and a fuel channel (3.1), which leads into the suction port (1). A linearly movable valve needle (5) is arranged to extend into the fuel channel (3.1) mainly perpendicular to its longitudinal direction and to open or close this, whereby the suction port (1) is possible to throttle down or close with a throttle (4) which is movable between an open position and a closed position. The valve needle is in connection with a maneuver arm (6), which in turn is in connection with the throttle (4) and is arranged to open the nozzle (3) when the throttle (4) is opened and to close when the throttle (4) is closed.
