Abstract: The invention relates to a fuel injection system for a multi-cylinder internal combustion engine having a first high-pressure accumulator and having a second high-pressure accumulator. The fuel injection system also has a high-pressure pump, wherein the first and the second high-pressure accumulators have a number of ports for injector supply lines corresponding to the number of cylinders of the internal combustion engine. A damping volume for damping pressure pulsations between the high-pressure accumulators and the high-pressure pump is integrated into one of the high-pressure accumulators.

Abstract: The invention relates to a component to be loaded with internal pressure, which in its interior has various bores that intersect one another. In particular, such components are used in the field of so-called common rails. Since in fuel injection systems these components are not only under very high internal pressure but the internal pressure is moreover subject to periodically severe fluctuations, correspondingly stringent demands in terms of strength must be made. By geometrically optimizing the intersection region of the bore of the high-pressure fuel reservoir and the bore for the connection, the result in cross section is an elliptical design. By embodying the bore intersection as an ellipse, the stresses in these local regions can be reduced, and as a consequence the permissible internal pressure can intrinsically be increased.

Abstract: The invention relates to an internally pressurized component, the inside of which contains a bore extending in its longitudinal direction, which has a number of connecting parts. In order to permit the geometry of the bore to be optimized, the cross section of the bore is non-cylindrical in a middle part and has a cylindrical cross section in at least one end region of the end parts, wherein the cross section of the middle part transitions continuously into the cross section of the end part.
