Abstract: A spray orifice disk for a valve for a flowing fluid and, in particular, for a metering or injection valve for an internal combustion engine, including a disk body and a spray orifice set-up, which is formed in the disk body and is configured with at least one spray orifice for dispensing supplied fluid, and including at least one channel for supplying the fluid to the spray orifice. The spray orifice, the channel and/or the transition between the channel and the spray orifice being configured to form a swirl geometry of the spray orifice disk in such a manner, that during operation, due to interaction of one or more jets of the fluid emerging from the spray orifice in turbulence atomization, an oval cross-sectional pattern of the spray is formed, in particular, in the form of a flat spray.

Abstract: A spray orifice disk for a valve for a flowing fluid and, in particular, for a metering or injection valve for an internal combustion engine, including a disk body and a spray orifice set-up, which is formed in the disk body and is configured with at least three spray orifices, each for dispensing supplied fluid. The spray orifices are being configured to form a swirl geometry of the spray orifice disk in such a manner that during operation, a combined spray is formed from at least three individual jets by interaction of a plurality of at least three individual jets of fluid emerging in atomized form from the spray orifices.
