  • Injector sleeve
    Patent number: 9593654
    Abstract: An injector sleeve adapted to be mounted in a cylinder head of an internal combustion engine, where the injector sleeve comprises a tapered inner surface which constitutes a sealing surface for an injector, where the hardness of the tapered inner surface is higher than the hardness of the outer surface of the injector sleeve. The injector sleeve is produced in a cold forming process. The advantage of the invention is that the injector sleeve is provided with a sealing surface for an injector which is harder than the outer surface of the injector sleeve. In this way, a sealing surface for an injector having small tolerances is obtained without further machining, where the outer surface may be turned to the desired dimensions.
