Abstract

The invention relates to a sealing geometry (40), in particular for a fuel injector (10) which can be acted on with system pressure. Said fuel injector (10) comprises components (18, 26) which are clamped together axially. A sealing surface (40) is of stepped design and comprises an abutment surface A and a sealing surface D, between which is formed a step height h.
