摘要： A bush incorporated in a common rail is formed with a smallest diameter orifice having a small inner diameter and an adjacent orifice having an inner diameter larger than that of the smallest diameter orifice on an inner peripheral face of the bush. A press-fitted portion, which is press-fitted into an inside-outside communication hole, and a non-press-fitted portion, which has a smaller outer diameter than the press-fitted portion, are formed on an outer peripheral face of the bush. The smallest diameter orifice and the press-fitted portion are deviated from each other in an axial direction of the bush to prevent an overlap in a radial direction of the bush. Thus, even if the bush is tightly press-fitted into the inside-outside communication hole, decrease of the inner diameter of the smallest diameter orifice can be averted.

摘要： In a common rail for accumulating highly pressured fuel, a cylindrical body is provided with a chamber for accumulating highly pressured fuel and a delivery port which connects the chamber to the outer circumference thereof and communicates via a pipe-joining unit with a conduit in a distribution pipe. The longitudinal center axes of the chamber and the cylindrical body are disposed substantially coaxially with each other, and each of the longitudinal center axes of the delivery ports and the longitudinal center axis of the cylindrical body are skewed to each other. Accordingly, the durability of the cylindrical body is improved, and the thickness of the cylindrical body is uniform and the forging form of the cylindrical body becomes symmetric. The length of the delivery port is extended so that the durability of the cylindrical body is improved.

摘要： A flow damper is provided with a clearance to absorb a deformation occurring in proximate to a lower end of the valve body by the clearance on an entire outer circumference of a lower side of a large diameter portion of a piston. By the configuration in this manner, even if the slight deviation in the accuracy or the shape of the seat surface occurs a radially inward deformation of a lower portion of the valve body when the valve body is fastened to the common rail body at a large axial force, the clearance absorbs the deformation. Thus, the deformation of the valve body does not affect the piston sliding hole. Accordingly, a sliding clearance of the piston does not change, not to spoil a slide motion of the piston.

摘要： In a pipe joint structure, a second screw thread formed on an outer circumference end of a joint member is screwed deep into a first screw thread formed on an inner circumference of a cylindrical joint fitting member whose axial end is bonded to a common rail body so that a second flat surface at an axial end of the joint member is pressed against a first flat surface on an outer circumference of the common rail body to form a fluid tight sealing surface therebetween in a state that a fluid passage opened to the second flat surface communicates with a through-hole opened to the first flat surface. Accordingly, even if a position of the joint fitting member to the common rail body is slightly shifted, fluid tight sealing between the first and second flat surfaces is assured.
