ンプ。 A plunger for pumping fuel is reciprocated to pump fuel, and a piston is disposed opposite to the tip of the plunger via a plunger pressurizing chamber, and the pressure of the plunger pressurizing chamber causes the piston to pressurize the piston. In a fuel injection pump configured to displace the piston and increase the volume of the plunger pressurizing chamber when the set thickness of the biasing means for biasing the piston is overcome, the plunger pressurizing chamber and the fitting chamber of the piston are provided. 1. A fuel injection pump characterized in that a communication passage communicating with the internal combustion engine is configured to be opened and closed by an electromagnetic on-off valve that is controlled to open and close depending on the operating conditions of the internal combustion engine.
