    摘要： The fuel injector includes an orifice plate being situated downstream from a valve-seat body having a fixed valve seat, the orifice plate having at least one outlet opening. Provided directly upstream from the outlet openings is an inflow opening having an annular inflow cavity. The valve-seat body covers the inflow cavity in such a way that the downstream outlet openings of the orifice plate are covered. A boundary surface of the valve-seat body lying opposite the orifice plate is designed such that, beginning at an exit opening, the height of the inflow opening decreases continuously in a first section up to the at least one outlet opening, while the height of the inflow opening in a second, radially outer section remains largely constant. The fuel injector is particularly suitable for use in fuel injection systems of the mixture-compressing internal combustion engines having external ignition.

    摘要： The fuel injector including an orifice plate which is provided with a multitude of outlet openings and situated downstream from a valve-seat body having a fixed valve seat. Directly upstream from the outlet openings is an inflow opening having an annular inflow cavity. The valve-seat body covers the inflow cavity in such a way that the downstream outlet openings of the orifice plate are covered. The outlet openings each have an inflow region whose diameter D1 is considerably larger than the diameter D2 of a region that abuts at a sharp angle directly downstream therefrom, which forms the narrowest cross section of the outlet opening and from where the outlet opening widens in the flow direction to a diameter D3 in a trumpet-shaped manner. The fuel injector may be particularly suitable for use in fuel injection systems of mixture-compressing ignition engines having externally supplied ignition.

    摘要： A fuel injector includes an orifice plate situated downstream from a valve-seat body having a fixed valve seat, the orifice plate having at least one outlet opening. Provided directly upstream from the outlet openings is an inflow opening having an annular inflow cavity. The valve-seat body covers the inflow cavity in such a way that the downstream outlet openings of the orifice plate are covered. The inflow cavity directly upstream from the at least one outlet opening is configured such that the flow approaches the at least one outlet opening largely at a right angle to the longitudinal extension of the outlet opening. With regard to the cross section, the at least one outlet openings has a polygonal form, in particular one that encloses at least one triangle, or it has a meander shape with a plurality of curves in the outer contour. The fuel injector may be particularly suitable for use in fuel injection systems of the mixture-compressing internal combustion engines having external ignition.

    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： A fuel injector for the direct injection of fuel into a combustion chamber of an internal combustion engine is provided, which injector includes a valve needle having at its spray-discharge end a valve-closure member, which cooperates with a valve-seat surface formed on a valve-seat member to form a sealing seat. At least one swirl channel is provided in a section of the valve-seat member surrounding the valve needle, and at least one spray-discharge orifice is provided in the valve-seat member. The at least one swirl channel, when viewed through the swirl channel in the flow direction of the fuel, is inclined counter to the spray-discharge direction relative to the center axis of the valve needle.

    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.
