    摘要： A fuel injection valve (1), in particular for the direct injection of fuel into a combustion chamber (18) of an internal combustion engine, has a valve needle (3) which is arranged in a nozzle body (2) and can be actuated by an actuator, and a valve closing body (4) which is operatively connected to the valve needle (3) and, for opening and closing the valve (1), interacts with a valve seat face (6) which is formed on a valve seat body (5), wherein the valve seat body (5) is provided with at least one spray hole (7). The at least one spray hole (7) comprises a first cylindrical section (40) having a fuel inlet opening (36) and a second cylindrical section (41) which is arranged downstream of the first cylindrical section (40) and has a fuel outlet opening (37), wherein the first and the second cylindrical sections (40, 41) do not extend coaxially with respect to one another.

    摘要： An injection valve for injecting a liquid comprises an electromagnetic actuator (10, 11, 12), a movable valve needle (5) and a valve closing body (7) which, together with a valve seat surface (29), forms a sealing seat, and a perforated disc (21) which is arranged downstream of the sealing seat and has at least one inlet region (41) and at least one outlet opening (44). Here, an upper functional plane (40) which has the at least one inlet region (41) has a different opening geometry in cross section from a lower functional plane (42) which has the at least one outlet opening (44). A plurality of inlet regions (41) are provided in the perforated disc (21), which inlet regions (41) are provided in each case as a locally delimited cavity with a rectangular or bathtub-shaped contour, which are adjoined by in each case one outlet opening (44) in the flow direction, wherein the outlet openings (44), starting from the centre point of the respective inlet regions (41) and with a longitudinal axis and a transverse axis theoretically passing through it, have an asymmetry with regard to both axes.

    摘要： The invention relates to a fuel-injection valve, which is characterised in that an injection orifice plate (23) is located downstream of a valve seat body (16) comprising a fixed valve seat (29), said plate having at least one outlet opening (24). An inflow opening (19) comprising an annular inlet cavity (26) is provided directly upstream of the outlet openings (24). The valve seat body (16) protects the inlet cavity (26) in such a way that the downstream outlet openings (24) of the injection orifice plate (23) are covered. The inlet cavity (26) that lies directly upstream of the outlet opening(s) (24) is configured in such a way that fuel essentially streams towards the outlet opening (24) at a right angle to the longitudinal extension of the outlet opening (24). The cross-section of the outlet opening(s) (24) is configured as a polygon, in particular with a triangular shape, or has an undulating shape with several arcs along its external contour. The fuel-injection valve is particularly suitable for use in the fuel-injection systems of compressed-mixture, spark-ignited internal combustion engines.

    摘要： Disclosed is a fuel injection valve which is characterized in that a perforated disk (23) that is provided with a plurality of discharge ports (24) is disposed downstream of a valve seat member (16) comprising a fixed valve seat (29). An inlet port (19) encompassing an annular hollow inflow space (26) is provided directly upstream of the discharge ports (24). The valve seat member (16) covers the hollow inflow space (26) in such a way that the discharge ports (24) of the perforated disk (23) which are located downstream are covered up. Each discharge port (24) is provided with one inlet zone (33) whose diameter D1 is significantly greater than the diameter D2 of a zone which is located immediately downstream thereof at a sharp angle and forms the narrowest cross section of the discharge port (24), the discharge port (24) expanding in a trumpet-shaped fashion to a diameter D3 from said zone in the direction of flow. The inventive fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignited internal combustion engines.
