ABSTRACT:
The invention is directed to a carburetor arrangement for an internal combustion engine of a working tool such as a portable hand-held chain saw, a cutoff machine or the like and includes a tank from which the fuel is conducted to the main nozzle of a carburetor via an inlet valve of the carburetor. A tank pressure blocking valve is mounted in the fuel feed line between the tank and the nozzle. The valve body of the blocking valve is pressed tightly against its valve seat in the direction of fuel flow and pressure drop when the engine is at standstill. During starting and running of the engine, the valve body is lifted from its seat by the underpressure condition caused by the engine and is moved in a direction opposite to an overpressure in the tank and against the flow of fuel.
