Abstract

A swirl disk distinguishes itself in that it has at least one inlet region and at least one outlet opening, the at least one outlet opening being introduced in a bottom base layer. The swirl disk also has at least two swirl channels, which empty into a swirl chamber, the swirl chamber being provided in a swirl-generating layer. The swirl channels being situated and positioned such that when a fluid flows through, at least two swirl flows are generated next to one another in opposite directions, each one having its own jet branch. The swirl disk is particularly suitable for use on a fuel injector, in particular a high-pressure injector for directly injecting fuel into a combustion chamber of a mixture-compressing, spark-ignition internal combustion engine.
