The fuel distribution pipe 10 includes a pipe part 11 that stores the fuel in a high-pressure state, and a plurality of housings 12 that are joined to the pipe part 11 and supply the fuel to the fuel injection devices 3. A first housing 12A from among the plurality of housings 12 includes a first connection opening 17 that is connected to the fuel pipe 2 and communicates with the pipe part 11.

A sealing cartridge (18) for an injector of an internal combustion engine seals a medium-filled first chamber (6) and a medium-filled second chamber (7). The chambers (6, 7) are between an injector (1) that is movable axially along an injector axis (9) and a housing (2) receives the injector (1). The sealing cartridge (18) is configured to receive the injector (1). The sealing cartridge (18) has at least one seal (11; 20) disposed in a receptacle housing (19) of the sealing cartridge (18). The receptacle housing (19) has a first housing portion (29) configured to receive the seal (11; 20) on the shell face (31) of the receptacle housing (19), and a second housing portion (30) configured to receive the seal (11; 20) on an internal face (25). An injector assembly (38) also is provided and has an injector (1) that is received in the sealing cartridge (18).

A fuel rail for an engine includes a tubular body having an outer surface and an inner surface, the inner surface defining a longitudinally extending fuel bore. The fuel rail also includes a valve bore extending normal to the fuel bore and extending through the outer surface of the tubular body at a first end and completely through the fuel bore to a second end.

A fuel line assembly includes a fuel line having has an inner surface and an outer surface joined to each other by a fuel line aperture. A fuel injector socket has at one end a fixation saddle which is concave within which the fuel line is received such that the fixation saddle has a concave surface facing toward the fuel line. A fuel injector socket receiving bore extends into another end of the fuel injector socket to receive a fuel injector therewithin. A fuel injector socket aperture extends from the concave surface to the fuel injector socket receiving bore. An alignment tube provides fluid communication between the inner surface and the fuel injector socket receiving bore, wherein a portion of the alignment tube is circumferentially surrounded by the fuel line aperture and wherein another portion of the alignment tube is circumferentially surrounded by the fuel injector socket aperture.

The invention relates to a device (10) for a common rail fuel injection system (102), wherein the device (10) comprises a one-piece module (12) which comprises a common fuel line (14) and a plurality of injector bodies (16) in fluid communication with the common fuel line (14). The present invention also relates to a vehicle (100) comprising such a device (10). The present invention also relates to a method of manufacturing a device (10) for a common rail fuel injection system (102).

The flexibility of the attachment angle and attachment interval of the member (e.g., injector) attached to the joint member is increased to improve the flexibility of layout even in the case of the forged rail for high-pressure direct injection. In addition, the manufacturing cost can be reduced while keeping high strength of the joint portion. A rail body 1 manufactured by forging, the rail body 1 having a through hole 4 opened on a wall surface 3 for communicating a fuel passage 2 extending in an axial direction with an outside; and

a tubular joint member 6 manufactured separately from the rail 1 body and fixed to the rail body 1 at a position of the through hole 4 for allowing a fuel to flow from the fuel passage 2 through the through hole 4 are provided.

A solenoid valve for a fuel system has an electric coil and an armature disposed in a housing. A preassembled valve unit with valve seat, valve member, valve spring, and armature plate connected captively to each other is provided. In the valve unit, the valve seat is loosely secured between valve member and armature plate. The valve unit is inserted and secured in an open housing end and the valve spring contacts an inner shoulder of the housing. Armature plate and armature form a magnetic circuit. The valve member is supported on the armature plate and switched to open and close an outlet of the valve seat. By suppling current, a magnetic field is generated in the armature and attracts the armature plate into an operative valve position. The valve spring returns the armature plate into a rest position when the coil is currentless.

An engine (1) includes a cylinder head (3), a retainer (80), a pressing member (70), and an injector (40). The cylinder head (3) has an attachment hole (15) formed therein. The retainer (80) is attached to the cylinder head (3). The pressing member (70) has a pressed surface (77) configured to be pressed by the retainer (80). The injector (40) is inserted into the attachment hole (15) and has an indentation (46) configured to be pressed by the pressing member (70). The indentation (46) is arranged inside the attachment hole (15). The pressed surface (77) is arranged outside the attachment hole (15).

A fuel rail arrangement for an engine includes a fuel rail mounting cradle and a fuel rail fixed to the cradle. The fuel rail includes one or more outlets connected to respective fuel injector pipes. The fuel rail arrangement includes a clamp to fix both the rail to the cradle and to fix the fuel injector pipes to respective outlets in the fuel rail.

A vibration damping system for injection systems of motor vehicles includes an actively controllable actuator element, which is situated at a component of the injection system. The actuator element is situated at the component in such a way that, during operation of the injection system a vibration reduction of the injection system is achieved with the aid of an active control of the actuator element.
