Abstract
A carburetor for an internal combustion engine includes an intake channel section () as well as a throttle element journalled in the intake channel section (). The throttle element is adjustable between a full-load position () and an idle position (). A pump () is provided for additional fuel metering and this pump includes a pumping chamber () and a pump piston () guided in the pumping chamber (). The position of the pump piston () is coupled to the position of the throttle element. To ensure an optimal supply of the internal combustion engine with fuel in each operating state, the pump piston () is so coupled to the throttle element that fuel is pumped from the pumping chamber () into the intake channel section () when there is a displacement of the throttle element from the full throttle position () into the idle position ().
