Abstract: A release liner that can be produced in a few method steps (e.g., a coextrusion step), exhibits very good interlaminate adhesion, and has little tendency to deform and deviate from planarity. The release liner is for use on pressure-sensitive adhesives and comprises: a layer system (POL) comprising one or more layers and comprising in each layer, based in each case on the total weight of the layer, a total of at least 80% by weight of one or more polyolefins, where each layer of the layer system (POL) comprises polypropylene; at least one layer (PEL) comprising, based on the total weight of the layer (PEL), at least 80% by weight of polyethylene; and an anchoring layer that connects each layer (PEL) to the layer system (POL).

Abstract: A component for an injection system. The component includes a base body and at least one connecting piece, which is formed at the base body and used to connect an injector. The injector, during assembly, being insertable along a mounting axis into an accommodating space of the connecting piece. The base body and the connecting piece are formed by a forging operation. A recess is formed at an outer side of the connecting piece, in which, in the mounted state, an orienting element of the injector engages for restricting a rotational degree of freedom of the injector about the mounting axis. The connecting piece is post-processed after the forging so that a lateral surface of the recess is at least approximately configured with a predefined lateral height.

Abstract: 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.

Abstract: 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 (28) 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.

Abstract: 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.
