ンの燃料噴射ポンプ。 Inside the cylinder with suction port and distribution passage,
A plunger having a suction groove and a distribution port is rotatably and reciprocatably inserted, the suction port and the suction groove communicate with each other to supply fuel to the pressure chamber, and the rise of the plunger closes the suction port. In the fuel injection pump, the plunger is connected to the plunger stage section, and the plunger is connected to the plunger stage section, in which high-pressure fuel is supplied from the pressure chamber to the injection exit nozzle via the delivery valve by communicating the distribution port of the plunger with the distribution passage of the cylinder. The large diameter part that determines the effective stroke from the start of pumping to the end of the plunger and the small diameter part that pressurizes the fuel are formed with steps, and a collar is slidably inserted into the small diameter part of the plunger. At the same time, this collar is slidably fitted into the cylinder, and a spring that presses and biases this collar toward the stepped portion of the cylinder is interposed between the innermost part of the cylinder and the collar. A diesel engine fuel injection pump featuring:
