초록

A fuel pump for a high-pressure fuel injection system is constituted by integrating into a single pump unit 15 a high-pressure fuel pump 4 for supplying high-pressure fuel to injectors 8 for injecting high-pressure fuel into cylinders of an engine 16 and a solenoid valve unit 6 for controlling the fuel pressure of the high-pressure fuel pump 4, and the pump unit 15 is adapted for mounting on the engine. The configuration decreases required installation space, enables use of a common heat installation system and reduces the number of installation steps.
