Abstract
The invention relates to a storage tank () in a motor vehicle for receiving an aqueous urea solution for the SCR of nitrogen oxide in the exhaust gas. The storage tank () comprises a tank body which forms a storage volume () for the urea solution. The storage tank () furthermore comprises a filling pipe for filling the storage volume () and means for venting the storage volume () during the refuelling, wherein the filling pipe () has a filling head () at a remote end, and the filling head () forms an orifice stub (). The orifice stub () defines an orifice () for receiving a fuel pump nozzle. Said orifice stub furthermore has an external thread for receiving a complementary union thread of a refuelling cylinder for refuelling by the gas displacement method. The orifice stub forms at least one secondary air opening when the refuelling cylinder is attached, and therefore, when a refuelling cylinder is attached, a sealing seat is bridged by the refuelling cylinder and refuelling by the gas displacement method is possible even if counterflow venting through the filling tube () does not take place.
