Abstract: The invention relates to a metering device (10) for introducing a process liquid or auxiliary agent into a flow pipe of an internal combustion engine, in particular for introducing a reducing agent into an exhaust gas pipe (12). Said device comprises an injection valve (22) and a receiving device (50) comprising a heat sink element (46) and a cover element (48). The injection valve (22) and the receiving device (50) are combined to form a structural unit by means of bonded connections (62, 64).

Abstract: The invention relates to a fuel injection valve, particularly used as injector for fuel injection units of air compressed, self igniting internal combustion engines. According to the invention, a nozzle body with a valve seat surface and a nozzle needle interacts with the valve seat surface as a sealing seat in order to control a fuel flow to an injection hole located downstream of the sealing seat of the nozzle body. The injection hole is rounded at an inflow region. The injection hole further includes a tapering and a cutting edge at an outer region of the hole. Thus high efficiency atomization of fuel close to the nozzle is possible.
