    摘要： The decoupling element for a fuel injection device according to the invention is characterized in particular in that a low noise design is implemented. The fuel injection device includes at least one fuel injector and a receiving borehole in a cylinder head for the fuel injector, and the decoupling element between a valve housing of the fuel injector and a wall of the receiving borehole. The decoupling element is a decoupling system made up of a contoured spring seat on a shoulder of the receiving borehole and a spring washer resting on the shoulder. The fuel injection device is suited in particular for direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignition internal combustion engines.

    摘要： A gear machine includes two externally intermeshing gear wheels enclosed by a housing that has a high-pressure connection and a low-pressure connection situated opposite one another. On an inner circumferential face of the housing, a notional boundary line is assigned to both gear wheels. The line runs parallel to the line of contact between the gear tooth tips of the gear wheels and the inner circumferential face. The intersection edge is located between the two boundary lines and the minimum distance between the intersection edge and the boundary lines are at least one pitch interval of the gear wheels. The cross sectional shape of the low-pressure connection deviates from the circular shape such that its cross sectional area overlapping the gear wheels is greater than the cross sectional area of a notional, circular low-pressure connection overlapping the gear wheels at the same minimum distance from the boundary lines.

    摘要： A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component, in particular a fuel distributor rail. A base body having a receiving space is provided for this purpose. The base body has an opening, via which a fuel fitting of the fuel injector is insertable into the receiving space of the base body. Furthermore, a first annular element is provided in the receiving space, which in the installed state on the one hand interacts with the fuel fitting inserted into the receiving space and on the other hand interacts with the base body. Furthermore, a second annular element is provided in the receiving space of the base body, the first annular element and the second annular element abutting against an outside of the fuel fitting in the installed state.
