    摘要: PROBLEM TO BE SOLVED: To uniform sizes of fuel particles in spray in an early stage of fuel injection not to generate large droplets that are less likely to evaporate in the spray in the early stage of the fuel injection.
    SOLUTION: A nozzle plate for a fuel injection device (3) is disposed opposed to a fuel injection port of a fuel injection device. A nozzle hole (6) through which fuel injected from the fuel injection port passes is formed at the nozzle plate (3). At this nozzle plate for the fuel injection device (3), the nozzle hole (6) has a fuel-flow-in-side opening end (6a) whose shape is a circular shape. The nozzle hole (6) is coupled to the fuel injection port via fuel guide channels (15 and 16). The fuel guide channels (15 and 16) have an opening (20) into the nozzle hole (6), and a pair of opposing channel sidewalls (21 and 22). The opening (20) has a channel width smaller than a hole diameter of the nozzle hole (6). One (21) of the opposing channel sidewalls (21 and 22) is formed to extend in a tangential direction of the nozzle hole (6). The fuel is directly flowed into the nozzle hole (6) to generate a flow of the fuel in a spiral pattern in the nozzle hole (6).

    摘要: The invention relates to a device for nebulizing or spraying or injecting liquid into an operating chamber, wherein at least one multiple jet nozzle (1) is provided, having at least two jet ducts (2, 3) for generating at least two liquid jets colliding at least partially with one another in a collision zone (7), such that a jet substantially in a fan shape can be produced, the extent of which in a fan plane is larger or at least twice as large as in the direction transverse to this fan plane, wherein a nozzle body (1) of the multiple jet nozzle (1) comprises at least the two jet ducts (2, 3), whereby a fan jet which is as stable and/or as controlled as possible is produced. This is achieved according to the invention in that a distance (A) of the nozzle body (1) from the collision zone (7) and/or a collision point (7) of the at least partially colliding liquid jets is between 0 millimetres (mm) and 15 times a diameter (D) of the jet duct/s (2, 3).

    摘要: A method (400) of laser drilling a component is disclosed. The method (400) includes contacting a sacrificial material (130) with the component. The method (400) also includes aligning a laser drilling tool (116) with the sacrificial material (130) and the component. The method (400) further includes incidenting a laser beam (122) on the sacrificial material (130). The method (400) includes containing a trumpet effect caused by the laser beam (122) within a thickness of the sacrificial material (130). Further, the method (400) includes forming a reverse tapered orifice (110) within the component. The method (400) also includes removing the sacrificial material (130) from the component.

    摘要: An injection valve for internal combustion engines is specified, which injection valve has a sealing seat, formed by a valve seat (14) and a closing head (15) of a valve needle (16), and a plurality of spray holes (21) which are arranged downstream of the sealing seat. The spray holes (21) of stepped cross section in each case have at least one upstream hole inlet section (22), with a very small hole cross section and a hole inlet opening (221), and a downstream outlet section (23) with a very large hole cross section and a hole outlet opening (231). In order to avoid undesired depositing of burnt fuel on the edges of the hole outlet openings (231), all hole outlet sections (23) are connected to one another via a groove (25) with a groove opening which points downstream.
