摘要： PROBLEM TO BE SOLVED: To provide the high pressure fuel injection pipe for a diesel engine having extremely high safety which can collect fuel which leaks from an injection pipe main body and seat part. SOLUTION: In a high pressure fuel injection pipe having a structure with an outer pipe 2 consisting of another body is piled on the outer periphery side of an injection pipe main body 1, the end vicinity of the outer pipe 2 is engaged with a tightening nut 3, while interposing a seal member 4a and the push-pressed seat surface made by the connection head 1-1 of the injection pipe main body is contactingly engaged with the pressure receiving seat surface 8-1 of a counter part member 8a and tightened following the push-press at the connection head by the screwing of the tightening nut and connected to the partner member, an annular washer 3 provided with at least one fine hole 5-1 radially on the circumference is inserted between the connection head of the injection main body and tightening nut, and further, a drain hole 3-1 is bored between the washer of the tightening nut and partner member and the fuel leaked from the fine hole of the washer or seat part 9 to the inside of the tightening nut is collected from the drain hole.

摘要： PROBLEM TO BE SOLVED: To provide a high-pressure fuel injection tube for a common rail system, having resistance to breakage from fatigue that is caused by inner pressure of 200 MPa or above and capable of preventing breakage from fatigue at a bend portion as much as possible. SOLUTION: The high-pressure fuel injection tube having a bend portion is constructed from a thick-wall small-diameter steel tube, a connection head formed of a spherical seat surface, a circular flange provided at an interval in the axial center direction from the seat surface, and a conical surface continuous from the seat surface tapered toward a tip is provided at a connecting end portion of the steel tube, and a fastening nut engaging with the pressure receiving surface of the annular flange portion is assembled to the tube. The injection tube has the connecting head portion whose inner peripheral surface has a flat surface similar to the inner peripheral surface of the steel tube, has the bend portion with the flatness of the inner diameter of 6% or less, has hardness Hv of 285 or above, and has tensile strength of 900 MPa or above.
