Abstract

A fuel injection valve, which may be inserted into a locator bore of a cylinder head of an internal combustion engine, has a sealing ring located peripherally around the fuel injection valve in the locator bore. The sealing ring has a contact surface, having the shape of a spherical segment, toward the fuel injection valve, which presses against a corresponding counter surface, having the shape of a spherical segment, of the fuel injection valve.
