    摘要： A fuel injector, in particular for a high-pressure injector for direct injection of fuel into a combustion chamber of an internal combustion engine, has compression of a fuel/air mixture with spark ignition. On the downstream end of the valve a valve seat element is provided, to which a perforated disk acting as a flow restrictor is connected downstream. A swirl element is situated upstream from the valve seat which imparts an atomization-promoting rotational motion to the fuel to be injected. In the valve seat element downstream from the valve seat, an elongated outlet orifice is provided which opens directly into an orifice in the perforated disk attached to the valve seat element. The width of the outlet orifice is greater than the width of the orifice in the perforated disk, at least at its narrowest location, so that it is possible to adjust the steady-state flow rate of the valve at the orifice.

    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.

    摘要： A fuel injector, in particular for direct injection of fuel into the combustion chamber of an internal combustion engine, includes a valve-closure member which forms a sealing seat together with a valve-seat surface which is formed on a valve-seat member, and several injection orifices, each of which is connected with at least one spiral groove so that an outer edge of the swirl grooves coincides in part with a circumferential edge of the injection orifices. The swirl grooves extend generally perpendicular to a center line of the injection orifice associated with them.

    摘要： A swirl disk distinguishes itself in that it has at least one inlet region and at least one outlet opening, the at least one outlet opening being introduced in a bottom base layer. The swirl disk also has at least two swirl channels, which empty into a swirl chamber, the swirl chamber being provided in a swirl-generating layer. The swirl channels being situated and positioned such that when a fluid flows through, at least two swirl flows are generated next to one another in opposite directions, each one having its own jet branch. The swirl disk is particularly suitable for use on a fuel injector, in particular a high-pressure injector for directly injecting fuel into a combustion chamber of a mixture-compressing, spark-ignition internal combustion engine.
