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 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.

摘要： The invention relates among others to a method for producing outlet openings (32) in a valve, in particular a fuel injection valve. The injection valve has a fuel inlet (2), an excitable actuating device (1, 2, 19) by which a valve closing member (28) is movable, a fixed valve seat (27) embodied on a valve seat element (26), with which seat the valve closing member (28) cooperates to open and close the valve, and at least one outlet opening (32), as a fuel outlet, provided downstream of the valve seat (27). The at least one outlet opening 32 is produced in such a way that in a first method step, a through hole is created in the valve seat element (26), and in a second method step, from the ejection end of the through hole, an outlet region is created that is altered in shape and/or size and/or contour compared to the through hole.
