装置。The high-pressure plunger pump is equipped with a low-pressure fuel feed pump and a high-pressure plunger pump that further pressurizes the discharged fuel. The fuel injection pump consists of a control sleeve that opens and closes a distribution port that pressure-feeds the fuel sucked into each cylinder to the fuel injection nozzle of each cylinder, and a cut-off port formed in the plunger that releases high-pressure fuel depending on the accelerator opening.
A fuel injection pump characterized in that a relief valve is interposed in the pressure release passage connecting the high pressure chamber and the low pressure side, and a cam mechanism is provided to vary the relief spring set load of the relief valve according to the operating condition. Injection rate control device.
