ABSTRACT:
A fuel injection pump device for an internal combustion engine, in which a mechanical correcting signal continuously generated from a bellows in response to change in atmospheric pressure is transmitted to an adjusting member associated with a pump to adjust an amount of fuel injected into the engine by the pump. Transmission of the mechanical correcting signal from the bellows is limited such that the mechanical correcting signal is allowed to be transmitted to the adjusting member in a range in which the atmospheric pressure is below a predetermined level, but is prevented from being transmitted to the adjusting member when the atmospheric pressure is above the predetermined level.
