    摘要: A fuel injector with a magnetic coil, which cooperates with an armature acted upon by a restoring spring, the armature forming an axially movable valve part together with a valve needle. A valve-closure member, which forms a sealing seat with a valve-seat member, is provided at the valve needle. An inner pole and an outer pole form a magnetic circuit with the magnetic coil. A membrane is positioned at an inflow-side end face of the inner pole, which includes at least one orifice, which is covered by the inner pole in the dosed state of the fuel injector.

    摘要: A fuel injection valve is described which has a swirl disk downstream from a valve seat, the swirl disk being made of at least one metallic material, having at least two swirl channels opening into a swirl chamber, and in which all layers are adheringly deposited directly one on top of the other by electroplating (multilayer electroplating). The swirl disk is installed in the valve so that the surface normal to its surface forms an oblique angle other than 0° with the longitudinal valve axis, so that a jet angle &ggr; with respect to the longitudinal valve axis is formed due to the orientation of the swirl disk. The fuel injection valve is particularly well suited for direct injection of fuel into the combustion chamber of a compressed mixture externally ignited internal combustion engine.

    摘要: A fuel injector for fuel-injection systems of internal combustion engines includes an actuator, a valve needle, which is able to be activated by the actuator to actuate a valve-closure member, which, together with a valve-seat surface formed at a valve-seat member, forms a sealing seat; and a plurality of spray-discharge orifices which is formed in the valve-seat member. At a discharge-side end of the fuel injector, a nozzle-orifice cover is positioned, which shields the spray-discharge orifices from the combustion chamber of the internal combustion engine.

    摘要: A fuel injector, for example, a high-pressure injection valve for the direct injection of fuel into a combustion chamber of an internal combustion engine having external ignition, which is distinguished in that an outlet orifice is provided downstream from the valve seat which, at its downstream end, has a slot-forming element that largely closes off the outlet orifice. Between the outlet orifice and a front face of the valve-seat member, the slot-forming element leaves open a slot-shaped flow outlet, through which a fuel spray may be spray-discharged in a fan-jet pattern.

    摘要: Fuel injection valve is described which possesses a multilayer swirl valve downstream from a valve seat shaped onto a valve seat element, at least these two components being installed from the inflow direction into a passthrough opening of a valve seat support. The valve seat support has a lower base region that provides for a reduction in the cross section of the passthrough opening downstream from the valve seat. The fuel injection valve is suitable in particular for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignited internal combustion engine.
