    Abstract: The invention relates to a sealing element (26; 26a) for a high-pressure connection (25) in a fuel injector (10; 10a); said sealing element (26; 26a) is in the form of a sleeve and includes, on the outer circumference thereof, a radially outward-protruding first sealing zone (31, 32) designed to rest against a part (11, 12). According to the invention, at least two first sealing zones (31) are provided which are axially located at a distance from one another in relation to a longitudinal axis (27) of the sealing element (26; 26a).

    Abstract: The leakage detection arrangement for detecting a leakage in a fuel injection system comprises a fluid chamber (1) arrangeable in fluid communication with a leakage channel (2, 3), an indicator element (5) that is configured to move due to fuel pressure in the fluid chamber (1) from a retracted position to a protruding position thus indicating a leakage, and a retaining element (6), which is arranged around the indicator element (5) and configured to keep the indicator element (5) in the retracted position and allow movement of the indicator element (5) to the protruding position when the force applied to the indicator element (5) by the fuel pressure in the fluid chamber (1) exceeds a predetermined threshold. The arrangement comprises a groove (7) which is arranged in a part (8) surrounding the indicator element (5) and which is configured to accommodate the retaining element (6).

    Abstract: In a fuel injector 10, a distal end portion is fitted into a mounting member. A fuel joint 20 having a connecting pipe portion 22 is liquid-tightly connected to a proximal portion of the injector 10. A joint pressing member 30 which restricts the displacement of the fuel joint 20 in the direction away from the mounting member is provided. The joint pressing member 30 is fixed by fastening to the mounting member. The injector 10 is fixed to the mounting member by restricting the displacement of the fuel joint 20 by the joint pressing member 30. The injector 10 and the fuel joint 20 can be attached to each other at differing angles, to provide an injector assembly which can be easily used in common by vehicles having different specifications.

    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.
