| description | PROBLEM TO BE SOLVED: To provide a fuel-feeding system of a simple constitution, for enhancing pressure adjusting accuracy of fuel pressure, in the fuel-feeding system capable of switching the fuel pressure when operating the system. SOLUTION: This fuel-feeding system has a fuel tank 40, a fuel injection valve 44, a fuel pump 41 and a three-way valve 1 having a first opening part 21, a second opening part 22 and a third opening part 23 and capable of switching the first, second and third opening parts in a communicated state, and the first and third opening parts in a communicated state by closing the second opening part. The first opening part and the fuel pump are connected by a first external furl passage, and the second opening part and the fuel tank are connected by a second external fuel passage, and a first relief valve 42 of first setting pressure is arranged in the passage. The third opening part and the fuel tank are connected by a third external fuel passage, and a second relief valve 43 of second setting pressure higher than the first setting pressure is arranged in the passage. The fuel injection valve is arranged in the passage between the third opening part and the second relief valve. COPYRIGHT: (C)2009,JPO&INPIT |
