を特徴とする燃料噴射ポンプ。 It is equipped with a plunger fitted into a barrel and a pressurizing chamber formed between the barrel and the plunger. Fuel is sucked into the pressurizing chamber and compressed by the rotational reciprocating motion of the plunger, and the compressed fuel is transferred to the engine. A fuel injection pump that distributes and pressure-feeds fuel to the fuel injection valves installed in each cylinder includes a cylinder that communicates with a pressurizing chamber via a communication passage, a piston that is slidably fitted into the cylinder, and a piston that presses the piston. A fuel injection pump comprising a spring biasing toward a pressure chamber and a variable orifice provided in the middle of a communication passage, the opening area of the variable orifice being controlled in accordance with engine operating conditions.
