摘要: The fuel injector according to the invention is distinguished in that a particularly high structural strength and vibration resistance of the valve seat body (5) is provided. The fuel injector (1) includes an excitable actuator for actuating a valve closing body, which forms a seal seat together with a valve seat surface (6) formed on a valve seat body (5), and injection openings (7), which are formed downstream of the valve seat surface (6), the injection openings (7) being introduced into a middle area (44) of the valve seat body (5) protruding outwardly like a cone in the injection direction. The cone-like axially protruding middle area (44) of the valve seat body (5) ends radially outside the orifice areas of all injection openings (7) in a recessed depression (47), from which, in turn, an axially protruding border area (48) of the valve seat body (5) adjoins radially outwardly, so that an overall wavy cone contour of the valve seat body (5) is formed in cross section. The fuel injector is particularly suitable for direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignited internal combustion engine.

摘要: A system, which is used in particular as a fuel injection system for the high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element, which has a supporting surface. The cup has a contact surface on an underside, by way of which the cup is supported at the supporting surface of the holding element by a damping layer. The holding element is attached to the cup. In addition, the fuel injector has a collar, which is braced on the holding element. Because of the damping layer, vibrations are able to be dampened, and the noise transmissions is able to be reduced.

Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element. The holding element has an at least essentially straight first leg and an at least essentially straight second leg. The cup includes at least one recess, which extends through a wall of the cup. The first leg and the second leg are guided through the at least one recess. Furthermore, the connection sleeve of the fuel injector has a collar, which is braced on the first leg of the holding element and on the second leg of the holding element in order to secure the fuel injector on the cup.

摘要: A fuel injection system has a fuel distributor and multiple fuel injection valves each disposed on a cup of the fuel distributor. At least one injection valve is mounted on the associated cup by way of at least one holding element. An abutment surface is provided on the outer side of the cup. A support surface is configured on the underside of the cup. The holding element is moreover configured as a holding clamp. An abutment surface is provided on an outer side of the fuel injection valve. The holding clamp engages on the one hand behind the abutment surface of the cup and on the other hand behind the abutment surface of the fuel injection valve. The holding clamp furthermore pushes the fuel injection valve toward the support surface.

摘要: A connection piece for a valve, which is 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. In the connection piece, at least one support ring is situated on the sealing section, the support ring at least partially circumferentially surrounds the sealing section with respect to the longitudinal axis, the sealing section is configured, at least in one area along the longitudinal axis, in which the support ring surrounds the sealing section at least during operation, to have a circumference increasing in a direction along the longitudinal axis, and the support ring and the sealing section are configured so that, during operation, the support ring is displaceable in the direction in relation to the sealing section due to a fluid pressure of the fluid.
