The invention relates to a fuel metering device comprising a fuel chamber, a fuel inlet which can be opened and closed and leads to the fuel chamber, and at least one fuel outlet leading from the fuel chamber to a suction channel of an internal combustion engine. Part of a wall of the fuel chamber consists of a first element which can be moved according to a pressure difference between a pressure in the fuel chamber and an ambient air pressure, the element being coupled to a closing element for opening and closing the fuel inlet. The said fuel metering device enables a quantity of fuel, which is supplied to the suction channel for a pre-defined operating position of the internal combustion engine, to be automatically regulated according to the ambient air pressure.
