<P>PROBLEM TO BE SOLVED: To provide a fuel supply device reducing pressure pulsation in a fuel chamber and reducing noise radiated to an outside. <P>SOLUTION: Fuel is supplied from an open close valve 42 when fuel is injected from injectors 61-64 and pressure of fuel in a fuel chamber 33 drops. The open close valve 42 is supplied with fuel of higher pressure than the fuel chamber 33 via a fuel passage 43 branching off of a fuel pump 12 side of a pressure reducing valve 35. Consequently, pressure pulsation of fuel in the fuel chamber 33 is reduced even if fuel is injected from the injectors 61-64. Consequently, vibration of the rail 32 accompanying expansion and contraction of the rail 32 forming the fuel chamber 33 and expansion and contraction of the rail 32 can be reduced. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
