摘要： PROBLEM TO BE SOLVED: To provide a high pressure fuel pump discharging high pressure fuel with a simple mechanism. SOLUTION: A passage through which pressurized fuel passes is selectively switched to a passage in which a discharge adjusting chamber 60A communicates with an intake fuel chamber 20A, and a high pressure passage 70 by a single electromagnetic valve 10 and a back-flow preventing valve 45. Since it is not necessary to provide a plurality of electromagnetic valves for every pump chamber by this configuration, differently from a conventional high pressure pump, a discharge is adjusted with the simple mechanism. Since it is not necessary to provide a plurality of the electromagnetic valves, operating sound of the magnetic valve is suppressed. COPYRIGHT: (C)2009,JPO&INPIT
