Abstract
A tank system has a tank and a valve arrangement with a pilot-controlled relief valve. The relief valve has a main valve chamber, a filling line, a pilot and a control line. The main valve chamber is connected to the filling line and can be filled with a filling medium via the line. The control line is connected to the tank and the pilot in such a way that the pilot opens when a pressure in the control line exceeds a predetermined response pressure, which causes the relief valve to open. The valve arrangement has a reservoir filled with a flushing medium and is configured to direct the flushing medium at a flushing pressure into the control line and/or into the filling line.
