PROBLEM TO BE SOLVED: To reduce costs of a common rail injection device by forming a recessed part which exists in a blind hole shape on a common fuel rail connected to a plurality of injectors, and forming at least one part of a supply space on the recessed part. SOLUTION: A common rail injection device 10 has a rail 14 along a longitudinal shaft 12, and is continuously provided with two high pressure pumps 16 having each plunger piston 20 driven by each separate driving shaft 18. A compression space 28 to which each leading pipe 26 connected to each separate injector 22 is opened is formed in the rail 14, and two cylindrical recessed parts 36 communicated with a passage leading pipe formed per high pressure pump 16 are formed on one end part of the rail 14. A supply leading pipe 44 provided with an intake valve 42 is communicated with a supply space 40 defined by the recessed part 36, and the supply leading pipe 44 is communicated and connected with/to a compression medium string container through a pipe passage 46. |
