    • The invention relates to a storage tank (1) in a motor vehicle for receiving an aqueous urea solution for the SCR of nitrogen oxide in the exhaust gas. The storage tank (1) comprises a tank body which forms a storage volume (2) for the urea solution. The storage tank (1) furthermore comprises a filling pipe for filling the storage volume (2) and means for venting the storage volume (2) during the refuelling, wherein the filling pipe (3) has a filling head (9) at a remote end, and the filling head (9) forms an orifice stub (10). The orifice stub (10) defines an orifice (11) 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 (3) does not take place.
    • 本发明涉及一种用于接收用于废气中的氮氧化物的SCR的尿素水溶液的机动车辆中的储罐(1)。 储罐(1)包括形成用于尿素溶液的储存容积(2)的罐体。 储罐(1)还包括用于填充储存容积(2)的填充管和用于在加油期间排放存储容积(2)的装置,其中填充管(3)在远程处具有填充头(9) 并且填充头(9)形成孔口短管(10)。 孔口(10)限定用于接收燃料泵喷嘴的孔口(11)。 所述孔口还具有外螺纹,用于接收用于通过气体置换法进行加油的加油缸的互补联合螺纹。 当加油缸安装时,孔口短截线形成至少一个二次空气开口,因此当加油缸安装时,密封座由加油缸桥接,并且通过气体置换法进行加油即使逆流通风 填充管(3)不会发生。
