摘要： PROBLEM TO BE SOLVED: To provide a solenoid valve for flow control allowing precise control of the flow rate of a fluid. SOLUTION: In a variable discharge high pressure pump P, a low pressure fuel supplied from a feed pump P1 is absorbed into a pressure chamber 4a via the solenoid valve 6 and low pressure flow paths 17, 18, 19. The fuel absorbed into the pressure chamber 4a is compressed with the reciprocation of a plunger 3a and delivered to a common rail. The solenoid valve 6 has a communication flow path 71 provided in a valve element 63, one end (a left end in Fig.) thereof being formed as a fluid absorbing portion, and flow paths 66, 67 connecting the communication flow path 71 to the outer periphery of the valve element, the flow paths 66, 67 being formed as fluid discharging portions. In this case, such inconveniences are avoided that fuel pressure operates in the radial direction of the valve element 63 to produce greater sliding resistance between the valve element 63 and a valve case 6c. Thus, force on the valve element 63 is kept in a well balanced manner. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To adjust an amount of fuel with accuracy irrespective of engine operation conditions in a fuel injection device which controls fuel press-feeding amount by the use of linear solenoid. SOLUTION: A variable discharge amount high pressure pump P is driven while being accompanied with the rotation of an engine E. High pressure fuel compressed by a pump p is accumulated in a common rail R. The high pressure fuel inside the common rail R is injected and supplied to each cylinder of the engine E through electromagnetic fuel injection valves I. A discharge controlling device (solenoid valve) P2 composed of a linear solenoid is arranged on a fuel intake portion of the variable discharge amount high pressure pump P. An ECU 40 selectively executes according to the engine speed, a first control where a lift amount of a valve element of the solenoid valve is varied, and a second control where the lift amount of the valve element is varied and an opening time of the solenoid valve is varied. In such a case, the second control is executed unde low speed area of the engine E, and the first control is executed in other areas.
