摘要： PROBLEM TO BE SOLVED: To provide a high-pressure fuel injection pipe having a connection head which can prevent the plastic deformation of a connection washer (a washer or a sleeve washer) to thereby obtain high sealing performance.
SOLUTION: The connection head having an outer peripheral surface serving as a seat surface corresponding to its mated seat member is provided at the connection end portion of a thick steel pipe having a relatively small diameter. An annular concave channel section which is generated on the inner side of the head when forming the connection head is made to have a small depth and a gently-sloping shape. The connection washer is fitted on the outer peripheral surface at the neck lower portion of the connection head. In the high-pressure fuel injection pipe constituted as described above, a stair-like stepped portion having at least two or more steps without any slant portions is provided on the outer peripheral surface at the neck lower portion of the connection head. A stair-like stepped portion wholly or partially corresponding to the stair-like stepped portion of the connection head is provided on the inner peripheral surface of the connection washer so that the connection head and the connection washer are made in contact with each other.

摘要： PROBLEM TO BE SOLVED: To provide a high-pressure fuel injection pipe which has no cavitation erosion caused by a fluid pressure on the inner peripheral surface of a connection head, and which has excellent fatigue and rupture strength.
SOLUTION: The high-pressure fuel injection pipe has the connection head at a connection end part of a thick wall steel pipe of relatively small diameter. The connection head comprises a spherical-surface sheet surface, an annular flange part, and a conical part. The annular flange part is formed and arranged at intervals from the sheet surface in the axial center direction. Then the conical part stretching from the sheet surface is formed by being tapered down in the sheet surface direction in the area of the interval as far as the position of the annular flange part. Then an annular bowing concave ditch, which is deep and undercut, is provided to part of the conical part. Thus, the annular concave ditch inside the connection head, which is caused by the molding of the connection head, has an outline shape having a cross section with a shallow depth and a gentle slope, and a compressed residual stress exists on the inner peripheral surface of the annular concave ditch part.
