High pressure fuel injection unit.

摘要

The present invention relates to a high pressure fuel injection unit comprising a housing with a fuel injection timing control valve and a lift regulating solenoid actuator adapted to adjust the amount of fuel injected during a fuel injection cycle by means of a lift regulating member which is provided to engage a stopper portion of an injection valve body and, moreover, is adapted to selectively assume a predetermined lift regulating position in response to a lift regulating solenoid actuator being energized in advance of the fuel injection timing.
