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.
