Abstract: In a fuel injection system of an internal combustion engine, fuel is delivered from a high-pressure pump into a fuel rail. The quantity of the delivered fuel is influenced by a quantity control valve which is activated by an electromagnetic actuating device. The level of control of the quantity control valve during the transition from the closed state to the open state of the quantity control valve is provided in the form of a sufficiently flat, descending progression which allows a robust control of the opening motion with regard to the varying specimen properties.

Abstract: The invention relates to a high pressure fuel pump for a fuel injection system of an internal combustion engine, having a pump housing in which is formed a working space, into which fuel can be supplied from a low pressure region of the radial piston pump, the working space being delimited by a pump piston which can be driven, in order to pressurize the fuel, by an external drive, in particular by a camshaft of an internal combustion engine, wherein in order to meter the fuel quantity supplied to the working space, a throttle device having a variable throttle action is arranged on or in the pump housing.

Abstract: The invention relates to a fuel pump for a fuel system of an internal combustion engine, having a housing and a housing cap joined to the housing. In order to create a fuel pump which in its operation generates little airborne sound, structure-borne sound (vibration amplitudes) and pulsations in a low-pressure region of the fuel pump, it is proposed that the housing cap has at least one damping element, which is embodied as a sandwich construction having at least a first cover layer, a second cover layer, and a damping connection layer disposed between them. The damping connection layer has a markedly higher elasticity and/or higher material damping than the two cover layers, which may be constructed of sheet metal or the housing cap itself.

Abstract: A fuel system for an internal combustion engine includes at least one first fuel pump and a pressure region into which the fuel pump pumps and which communicates with an elastic volume reservoir. The elastic volume reservoir has a characteristic pressure/volume curve, which is defined by at least two points. It is proposed that a first point is defined by a first volume at a first pressure that is somewhat greater than a vapor pressure of the fuel at ambient temperature, and that a second point is defined by a second volume and a second pressure in the pressure region that corresponds to a maximum pressure; the difference between the first and second volumes corresponds at least approximately and at least to a value by which the volume of the fuel in the pressure region decreases upon cooling down from a maximum temperature to ambient temperature.

Abstract: The invention relates to a process for the production of a multi-layer image, preferably a multi-color image. A transfer film which is applied to a paper ubstrate and which is treated with laser irradiation is used. The transfer film has a laser-sensitive layer and a background layer arranged therebeneath. The laser-sensitive layer comprises laser-sensitive material, for example laser-sensitive pigments or other laser-sensitive coloring agents. The laser-sensitive material in the layer is region-wise bleached by laser irradiation. That results in a so-called laser-induced image component. As it is transparent or partly transparent, the background layer which is arranged therebeneath and which can have a printed image then becomes visible from above in that region. That therefore gives a multi-layer image which is formed by the laser-induced image component and by the background layer jointly.

Abstract: Described is a multi-layer body having two laser-sensitive layers 4, 32. The multi-layer body is a body laminated from the overlay films 30, 32, the inlets 90, 90 and the further overlay films 30, 30. At its underside the upper overlay film 30 has a layer structure applied there, by the application of a hot stamping film. The layer structure comprises a lacquer layer 50, a reflection layer 5r, a laser-sensitive layer 4, a background layer 5 and an adhesive layer 6. A diffraction and/or hologram structure 5b is provided in the lacquer layer 5c, the reflection layer 5r and the laser-sensitive layer 4. The second laser-sensitive layer is formed by the carbon-doped overlay film 32. By means of laser treatment, it is possible to produce a laser-induced, preferably colored image component in the upper laser-sensitive layer 4 and a further laser-sensitive image component, preferably in the form of a gray scale image, in the subjacent carbon-doped laser-sensitive layer 32.

Abstract: The present invention relates to a process for increasing the level of safeguard in respect of forgery of paper documents. For that purpose, applied to the paper document is a transfer film or laminating film having a laser-sensitive layer. This multi-layer body is then treated with laser radiation. In that case, a laser-induced marking is produced in the laser-sensitive layer, for example, by laser-induced bleaching, laser-induced color change or laser-induced blackening. Respective individualization of the document can be effected by way of that laser-induced marking.
