Abstract
A valve assembly for an injection valve includes a valve body with a central longitudinal axis, the valve body having a valve body groove extending circumferentially around the valve body and being designed to take in a gasket, the valve body groove having a first wall section and a second wall section, the wall sections configured to be coupled to the gasket in a manner that the valve assembly is sealingly coupable with a cylinder head of a combustion engine, and an injection nozzle enabling a fluid flow through the valve assembly. The second wall section is arranged relative to the first wall section in axial direction away from the injection nozzle. The first wall section extends to a first radius and the second wall section extends to a second radius, and the first radius is bigger than the second radius.
