The invention relates to a reducing agent tank for holding a liquid reducing agent as a so-called SCR tank. The SCR tank comprises at least one device for deaerating the tank, which device is closed off by means of at least one pressure-compensating element which permits an exchange of gas but which closes off the tank in a liquid-tight manner. The reducing agent tank also comprises at least one deaeration line which communicates with the pressure-compensating element, with the deaeration line being guided at least to a point above the maximum permissible fording level of the tank when the tank is in the installation position. The deaeration line has at least one first downward-sloping line section which branches into a second rising line section for deaeration and a third falling line section for gravity-induced condensate drainage.
Operating fluid tank for a motor vehicle, comprising a reducing agent tank for holding a liquid reducing agent for catalytic exhaust-gas denitrogenization, comprising at least one device for deaerating the tank, which device is closed off by means of at least one pressure-compensating element which permits an exchange of gas but which closes off the tank in a liquid-tight manner, and comprising at least one deaeration line which communicates with the pressure-compensating element, with the deaeration line being guided at least to a point above a maximum permissible fording level of the tank when the tank is in an installation position, and with the deaeration line having at least one first downward-sloping line section which branches into a second rising line section for deaeration and a third falling line section for gravity-induced condensate drainage.
