Patent ID: 11536234

Abstract:
The invention relates to an injector arrangement (1) having an injector nozzle (2) for injecting medium into a combustion chamber (3), particularly for injecting fuel into a combustion chamber (3) of an internal combustion engine, and having a sealing ring (20), which is pre-loaded in order to seal against a sealing surface (6) of a cylinder head (4), which comprises a through-hole (5), through which the injection nozzle (2) protrudes into the combustion chamber (3) and in which, in the radial direction between the injection nozzle (2) and the cylinder head (4), a heat protection sleeve (10) is arranged, one end (11) of which, facing the combustion chamber (3), is frictionally connected to the injection nozzle (2) by a radial pressing (12). In order to functionally improve the injector arrangement (1), an end (13) of the heat protection sleeve (10) furthest from the combustion chamber (3) is frictionally connected to the sealing ring (20) by an axial pressing (14).
