内燃機関の燃料噴射ポンプ。 The volume of the pressure chamber formed in the plunger barrel is changed by the axial reciprocating motion of the plunger, and the fuel in the low-pressure pump chamber is sucked and pumped, and the fuel is communicated with the pressure chamber and passed through the inside of the plunger. A pre-stroke control port that opens on the outer circumferential surface, a cut-off port for end-of-injection control,
In a fuel injection pump for an internal combustion engine, the fuel injection pump for an internal combustion engine is provided with a prestroke control member and an injection end control member that control opening and closing of each of these ports with respect to the pump chamber depending on a stroke position of a plunger, respectively. A fuel injection pump for an internal combustion engine, characterized in that the opening direction of the chamber is inclined at a predetermined angle with respect to the plunger center axis so that the opening direction of the chamber is substantially opposite to the direction of the pressurizing stroke of the plunger.
