<P>PROBLEM TO BE SOLVED: To provide a fuel injection system having a high pressure pump having a variable flow speed, for exhibiting high reliability, and composed of limited cost, to solve a defect of a fuel injection system of a conventional technology. <P>SOLUTION: This injection system has the high pressure pump 7 having a plurality of pump members 18 having the variable flow speed, driven by reciprocating motion and respectively arranged in corresponding suction valves 22. Fuel is supplied under low pressure from a suction pipe 10 of a pump 7 to an integral capacity part 28 via a solenoid valve 31 controlled as the function of operating a state of an engine 2. The integrated capacity part 28 communicates with the suction valves 22 via a corresponding discharge hole 29, and the solenoid valve 31 has a spray hole 36 respectively turning to at least one of the discharge hole 29 and generating injection of corresponding fuel. <P>COPYRIGHT: (C)2008,JPO&INPIT |
