PROBLEM TO BE SOLVED: To provide a fuel supply system promptly increasing pressure when a fuel pump is restarted, and also simplifying a structure. SOLUTION: A variable flow rate type is employed for the fuel pump 20, and a check valve 23 is provided to the delivery port 22 of the fuel pump. A branch passage 42 is branched from a branch point 41 in the middle of a fuel supply passage 40, and a jet pump 50 is provided in the branch passage 42. The injection nozzle 51 of the jet pump 50 is used as a throttle means for regulating fuel pressure. A remaining pressure holding valve 70 is provided on a passage in front of the injection nozzle 51. COPYRIGHT: (C)2010,JPO&INPIT
