    摘要： The invention relates to a valve for a flowing fluid, in particular a metering or injection valve for a flowing fluid, which valve comprises a valve seat body having a central opening and closing a valve chamber and a nozzle hole disk (18) arranged downstream of the valve seat body in the flow direction of the fluid and having at least one nozzle hole (19). In order to achieve an effective swirl processing of the fluid in a more cost-effective and compact manner, the nozzle hole disk (18) has a swirl chamber (20) that is associated with the nozzle hole (19) and is concentric to the nozzle hole (19) and at least one swirl channel (21) leading from the swirl chamber (20) to below the valve opening (14). The swirl chamber (20) and the swirl channel (21) are formed into the disk surface facing the valve body (12) as recesses. The swirl channel (21) comprises a channel cross-section and the nozzle hole (19) comprises a hole cross-section, which are dimensioned in such a way that the ratio of the channel cross-section to the hole cross-section is equal to or greater than 1.5.

    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.
