Device for discharging urea solution into an exhaust gas conduit
Abstract:
A device for the discharge of urea solution into an exhaust gas conduit (40) includes an injection nozzle (2) with a conduit connection (14) for the supply of urea solution, and a nozzle head which is conductively connected thereto. The urea solution may be supplied to an exhaust gas flow in a finely distributed manner by way of the nozzle head. Furthermore, the device includes a receiver (42), which surrounds an opening (46) in the exhaust gas conduit wall (44) and which is designed for the tight bearing of the nozzle head and for the releasable fastening of the injection nozzle (2). Moreover, a spring is provided for the non-positive fit bearing of the nozzle head in the receiver (42).
