摘要： The fuel supply apparatus for supplying fuel to an internal combustion engine has a fuel tank (2), a first fuel pump (6) that supplies fuel from the fuel tank to a fuel line (10), a second fuel pump (12) that supplies fuel from the fuel line (10) via a pressurized line to at least one fuel valve (16) and a fuel return line (22) that connects the fuel line (10) to the fuel tank for return of excess fuel. A shut off valve (30), which is closed at high temperatures, and a pressure regulator valve (26) are arranged hydraulically in series in the fuel return line (22). A fuel scavenger line (60) is provided, by which fuel at high temperatures is returned to the fuel tank (2). The fuel scavenger line (60) conducts the fuel back to the fuel tank (2), at least partially through the second fuel pump (12) and through a hydraulic resistance. Gas bubble formation is prevented by a high fuel supply pressure and by transfer of heat from the second fuel pump (12).

摘要： The invention relates to a quantity control valve for a fuel injection system, used in internal combustion engines, which includes a longitudinal slide that is movable in a valve housing between a first and a second control chamber and that allocates the fuel, flowing in from at least one low-pressure pump, to at least one high-pressure pump. For driving the longitudinal slide, the inflowing fuel is delivered into the first control chamber via a throttle or baffle valve, past the longitudinal slide. In the second control chamber, there is either a restoring spring that urges the longitudinal slide in the direction of its closing position, or the longitudinal slide there has an effective face-end surface area upstream of which a control line containing a throttle valve ends; this end face is smaller in surface area than the effective surface area of the face end in the first control chamber. In the closing position, the longitudinal slide blocks off the outlet bore with one of its cylindrical guide portions, while with regard to the inlet bore it has a narrowed region, which opposite the longitudinal slide bore leaves a flow cross section open that changes gradually to zero in the direction of the guide portion. In the valve, the flow of fuel is controlled by a targeted manipulation of a cross section via a long slide stroke.

摘要： The invention relates especially to a method for producing a product that is secure against fraud, i.e. a security product. The inventive method for producing a security product with a high degree of protection against fraud or tampering is characterized as follows: in a first step, a non-personalized and/or non-individualized support is provided with a non-personalized and/or non-individualized security element (100); in a second step and/or in further steps, the non-personalized and/or non-individualized support and the non-personalized and/or non-individualized security element (100) are personalized and/or individualized; a structure (101) that is optically effective in the security element (100) produces at least two especially, color effects; at least one of the color effects (106,107) only appears within a certain angular range to a vertical to the surface of the security element, and a personalizable and/or individualizable layer (102) that is provided in the security element (100) and/or a personalized and/or individualized layer that is provided in the security element (100) shows personalization and/or individualization information.
