Abstract
PURPOSE:To reduce the cost and improve the reliability by inserting a check valve and an orifice in a passage feeding the pressurized fuel oil to a fuel feed chamber formed on the small-diameter piston side of a piston in a cylinder coupled with the two-stage piston. CONSTITUTION:A two-stage piston 18 made of a large-diameter piston 12 and a small-diameter piston 13 is slidably coupled in a two-stage cylinder 17, and an operating oil chamber 6c formed on the large-diameter piston 12 side is communicated to the discharge side oil path system 19 of a high-pressure pump 2 connected to a pressure accumulator 3 or an operating oil tank 1 via a three- way selector solenoid valve 4. A fuel feed chamber 6d formed on the small- diameter piston 13 side is connected to a fuel injection valve 11 via a fuel pipe 141 and a high-pressure injection pipe 10 provided in the center line direction, and a fuel passage 7a provided with a check valve 14 and an orifice 90 is branch-connected to the fuel pipe 14a. The other end of this fuel passage 7a is connected to the discharge side of a fuel feed pump 8.
