A fuel distributor rail for a fuel injection system for an internal combustion engine in motor vehicles, in particular for gasoline engines. The fuel distributor rail comprises a main tube, wherein the main tube has a fuel channel extending in the longitudinal direction of the main tube. The main tube comprises at least two outlet openings, wherein the outlet openings branch off the fuel channel. A connecting element is arranged on the main tube, wherein the connecting element has an attachment wall that rests against the main tube. The connecting element is connected to the main tube in a material bonded manner and comprises at least two connecting pieces. The connecting pieces have a connecting channel each for the fluidic connection of an outlet opening to each injection nozzle.

Fuel distributor rail and method for manufacturing same

A screw connection device for fluid lines having a coupling nut with an interior space and having an internal threading running over the circumference of the interior space, as well as having a connecting element with an external threading. A line end of a fluid line is accommodated in the coupling nut, wherein the line end exhibits an end shape. When the internal threading of the coupling nut is screwed to the external threading of the connecting element, a locating surface disposed in the interior space of the coupling nut is moved toward the back end of the end shape, or vice versa, respectively. A spring element is disposed between the locating surface and the back end of the end shape, running over the circumference of the fluid line.

Screw connection device for fluid lines, in particular for motor vehicle fluid lines

A fuel distribution rail for a fuel injection system of an internal combustion engine has connected base tube sections defining a longitudinal fuel channel with connector devices fixed on the base tube and a force relieving groove provided on the outer surface of the base tube sections spaced from the connector devices which extend over at least a part, preferably at least over a greater part of the outer surface of the base tube. In one form a cylindrical base tube has a circular force relieving groove surrounding the base tube spaced from the connector device.

Fuel distribution rail

A fuel line, in particular a fuel line for a gasoline direct injection line system, having an inner steel tube and an outer steel tube, wherein the inner steel tube is accommodated in the outer steel tube in a force-locking manner. The inner steel tube is made of a corrosion resistant steel and the outer steel tube is made of an outer steel tube alloy, wherein a wall thickness of the inner steel tube is smaller than a wall thickness of the outer steel tube. A maximum carbon content of the outer steel tube alloy is higher than a maximum carbon content of the corrosion resistant steel. A thickness of the fuel line amounts to between 5% and 60% of an inner diameter of the motor vehicle fluid line.

Fuel line

A tube for a fuel injection system having an end form defining a spherical surface to seal against a receiver in fluid tight relation. The tube and end form may be made of steel or stainless steel. The spherical surface includes an integrated seal surface defining layer comprising material bonded to the spherical surface, which has a hardness lower than the hardness of the material of the end form and may comprise copper, copper-nickel alloy, copper alloy, nickel or manganese. In alternative forms, the material is deposited on the end form spherical seal surface by various processes including deposition by heating, using moistening effects, galvanic, evaporation, or any other suitable deposition process.

Tube fitting with integrated seal

A threaded component for connecting piping employed on motor vehicles includes a thread formed thereon and at least one unthreaded, contacting surface. A first coating having a first coefficient of friction is disposed on at least a portion of the thread, and a second coating having a second coefficient of friction is disposed on at least a portion of the unthreaded, contacting surface(s) of the threaded component. The first coefficient of friction is greater than the second coefficient of friction. In an embodiment an anti-corrosion coating is provided between the coatings and the component.

Threaded component and device for connecting piping

A tube connection device for connecting motor vehicle tubes, a tube having a front element on at least one end, this front element being equipped with a frontal sealing surface. A fitting enclosing the tube is provided, which presses the frontal sealing surface against a connection surface of a connection element. At least one separate pressure element, which at least partially surrounds the tube, is provided between fitting and front element. The fitting acts on the front element through the pressure element and the sealing surface is pressed against the connection surface in this way.
