    Abstract: The coupling device (40) comprises a holding fixture (30) being designed to be mechanically coupled to the fuel rail and comprising a through hole (42) extending between a first surface (44) and a second surface (46), the second surface (46) opposing the first surface (44) and being arranged and designed to face the cylinder head. Furthermore the coupling device (40) comprises a fastening element (48) being designed to be fixedly coupled to the cylinder head. The fastening element (48) comprises a head portion (50) and a shank portion (52) . The head portion (50) faces the first surface (44) of the holding fixture (30) and the shank portion (52) is being partially arranged in the through hole (42) and is designed to be in engagement with the cylinder head. In addition the coupling device (40) comprises a retaining element (64) being arranged inside the through hole (42), being coupled with the holding fixture (30), comprising in a given latch area (65) a cross-section restriction and being in engagement with the shank portion (52) at least in this latch area (65). The retaining element (64) is formed as a one-piece unit.

    Abstract: Provided is an end seal structure of a fuel rail for a gasoline direct injection engine, the fuel rail being constructed and arranged such that an end or both ends of a rail body composed of a tubular body such as a pipe is/are closed by an end cap or end caps, the end seal structure having a simple structure, making it possible for the end cap portion to meet higher pressure requirements. The end seal structure, in which an end or both ends of a rail body composed of a pipe is/are closed by a thread fastening type of an end cap or end caps having a cap-nut shape, is characterized in that a metallic gasket is provided between an inner wall surface of the end cap having the cap-nut shape and an end section of the rail body, the end cap having the cap-nut shape is screwed and fixed to the rail body, and the gasket is tightened by an axial force created by tightening of the end cap having the cap-nut shape so that the end of the rail body is sealed.

    Abstract: A method to manufacture a high pressure reservoir (10) adapted to be arranged in a diesel injection system, the reservoir (10) having an elongated body (12) extending along a longitudinal axis (X) from a first extremity (14) to a second extremity (16), the body (12) having a peripheral wall (18) defining an inner axial bore and a plurality of radial holes (22, 24) adapted to be complementary connected to high pressure pipes, the method (100) comprising the initial step:
    a) providing a seamless cylindrical steel tube, the central bore of the tube opening at both ends of the tube, said seamless tube forming the blank of the body (12);
    characterized in that the method further comprises a subsequent sequence of steps which are all controlled material-removal process steps.
