Abstract

In a fuel injection apparatus - in which the air-fuel ratio is maintained constant by an air sensor displaceable in the suction tube by the intake air drawn into the internal combustion engine with which the fuel injection apparatus is associated - in order to prevent undesired shifts in the metered fuel quantities in the low rpm range, the pressurized liquid used as a return force for the air sensor passes through a throttle assembly which throttles the liquid flow to an extent dependent upon the direction of flow therethrough.
