    摘要: A hydraulic connection via which a fuel injector is connectable to a fuel-conducting component and which includes a retaining bridge having a support surface. A connecting piece of a fuel injector is supportable on the support surface of the retaining bridge. A hydraulic connection being formed between the connecting piece of the fuel injector and a connection. A convexly curved bearing surface is provided on the connection, and a support surface is formed on the connecting piece of the fuel injector. A contact between the connecting piece of the fuel injector and the connection is implemented on the convexly curved bearing surface and the support surface for forming the hydraulic connection. The support surface is designed axially symmetrically with respect to a longitudinal axis. The support surface is designed in a widened manner in a direction from the connecting piece toward the connection along the longitudinal axis.

    摘要: A valve for metering fluid has an electromagnet for actuating a valve needle controlling a metering opening. The electromagnet generates, upon current flow, a magnetic flux that proceeds via an outer pole, a hollow-cylindrical inner pole, an armature displaceable on an armature guidance region embodied on the valve needle, and a working air gap delimited by the armature and inner pole. Disposed fixedly on the valve needle is an entraining element that penetrates axially displaceably into an entraining element guidance region embodied in the inner pole and has a radial stop shoulder for the armature which delimits a take-up travel or pre-stroke travel. The entraining element is extended into an additional inner pole having a pole surface formed by the stop shoulder, and is embodied magnetically conductively and a magnetic flux between the armature and valve needle is suppressed by way of a magnetically nonconductive material.

    摘要: A connection piece for a valve, which is utilized for metering a fluid, includes a sealing section, on which at least one annular sealing element is situated. The annular sealing element circumferentially surrounds the sealing section with respect to a longitudinal axis. Furthermore, the annular sealing element is supported on an end of the sealing section with the aid of a support ring. The sealing section has a circumference increasing along the longitudinal axis at least in an area along the longitudinal axis in which the annular sealing element surrounds the sealing section.

    摘要: A fuel injection device includes at least one fuel injector and a receiving bore in a cylinder head as well as a receiving opening of a fuel rail for the fuel injector. The fuel injector is sealed using at least one sealing ring against the walls of the receiving opening and secured in the receiving opening with the aid of a fastening element. A compensating element is provided that acts on the fastening element to prevent bending moments as a result of an asymmetrical suspension of the fuel injector at the fastening element from acting on the fuel injector. The fuel injector device is particularly suitable for directly injecting fuel into a combustion chamber of a mixture-compressing, spark-ignition internal combustion engine.

    摘要: A valve for metering highly pressurized fluid, having an inlet connector that can be placed into a connection socket of a fluid supply line, and a sealing assembly situated on the inlet connector, the sealing assembly having an elastically deformable sealing ring and a support ring made of plastic, which sealing assembly is supported on a radial support shoulder present on the inlet connector and seals against the connection socket. To prevent radial gaps between the support ring on the one hand and the inlet connector and/or the connection socket on the other hand, into which gaps the sealing ring extrudes under high pressure and becomes damaged, the support ring situated between the sealing ring and the support shoulder is made of an elastically deformable plastic material.
