An assembly for fuel-injection systems for connecting a fuel injector to a fuel-conveying component includes a retaining part that is used for mechanical fastening, and an attachment part, to which the fuel injector is hydraulically connectable. A connecting part is provided via which the attachment part, that is connectable to the fuel-conveying component, is connectable to the retaining part.

Fuel-injection system and assembly therefor

A fuel injector, especially for the direct injection of fuel into a combustion chamber of an internal combustion engine, includes a nozzle body able to be inserted into a recess of a cylinder head, a valve housing, a plug abutting the valve housing, and at least one fixation element, which fixes the nozzle body in its position in the recess, the fixation element extending from a connection region () between the valve housing and the plug on the spray-discharge side. The at least one fixation element has a reinforcement having a spherical contour at an outer periphery, the reinforcement being formed by at least one outwardly projecting element having an outwardly curving end face and/or having a planar end face.

Fuel injector and fuel-injection system

The fuel injection device according to the present invention is distinguished by a particularly effective sound-decoupling construction. The fuel injection device has at least one fuel injection valve, a receptacle bore for the fuel injection valve in a cylinder head, and a fuel distributor line having a fitting in which the fuel injection valve is placed in partially overlapping fashion. A connecting element is situated in the receptacle bore in such a way that the fuel injection valve is held in the connecting element in such a way that the fuel injection valve and the connecting element are held so that they do not contact any surfaces or walls of the receptacle bore of the cylinder head that do not run axially parallel to the fuel injection valve. The connecting element is attached immediately on the fitting of the fuel distributor line. The fuel injection valve is particularly well-suited for use in fuel injection systems of mixture-compressing externally ignited internal combustion engines.
