摘要

The injector has a jet needle guided in a housing (1), where a valve (7) is formed at a far end of the housing and needle. The valve is operated by lifting movements of the jet needle relative to the housing. The jet needle is formed as a hollow needle (3), where a stream of dosing fluid is guided in the direction of the valve and provided at the valve by a slanting passage in an area of the valve.
