摘要:
An injection valve of an internal combustion engine comprises a valve portion arranged in a bore of the valve housing, forming a high-pressure side annular chamber sealed in relation to the valve housing by the sealing contact of the valve portion with a shoulder of the bore and at an axial distance therefrom, by a sealing ring. A spacing sleeve is arranged in the annular chamber and keeps the sealing ring at a minimum axial distance from the shoulder of the bore.
