摘要： The fuel injector is characterized in that a multi-fan jet nozzle is disposed downstream of a valve-seat member having a fixed valve seat. The multi-fan jet nozzle is disk shaped, having a middle, bulged, crest-like nozzle area that has an elliptical elongation. In the nozzle area of the multi-fan jet nozzle used as an atomizer device, a plurality of directionally parallel spray-discharge slots is provided, which, for example, are arranged in a row. The fuel injector is particularly suitable for use in fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.

摘要： The fuel injector provides an oncoming flow out of spray-discharge orifices in a manner that reduces variance in the spray and flow-through characteristics variables. The fuel injector includes at least one excitable actuator and a valve element that is movable along a longitudinal valve axis, which collaborates in a sealing manner with a valve seat. Upstream of the valve seat, circumferentially a plurality of flow-through regions are provided, between which there are guidance regions for the valve element. The spray-discharge orifices downstream from the valve seats, whose number differs from the number of the flow-through regions, discharge the fuel finely atomized. At least two flow-through regions differ in size, such as circumferential width and/or radial depth, and/or contour. The fuel injector directly injects fuel into a combustion chamber of an engine using compression of a fuel/air mixture and spark 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： The fuel injector provides an oncoming flow, that is uniform and stable in time, of the spray-discharge orifices is produced and consequently, and a reduction in variance in the spray and flow-through characteristics variables. The fuel injector includes at least one excitable actuator and a valve element that is movable along a longitudinal valve axis, which collaborates in a sealing manner with a valve seat. Upstream of the valve seat, circumferentially a plurality of flow-through regions are provided, between which there are guidance regions for the valve element. The spray-discharge orifices downstream from the valve seats, whose number differs from the number of the flow-through regions, discharge the fuel finely atomized. At least two flow-through regions differ in size, such as circumferential width and/or radial depth, and/or contour. The fuel injector directly injects fuel into a combustion chamber of an engine using compression of a fuel/air mixture and spark ignition.
