The device has a tubular supply pipe (1) for supplying corrosion inhibiter to control valve (2) with a switching pipe (3). A drive (23) is configured to rotate switching shaft (4) provided in the switching pipe. The outlet ports (16a,16b) and outlet passages (17a,17b) respectively provided radially around switching pipe and switching shaft, are arranged such that relative angular positions of switching shaft with respect to switching pipe are configured to supply corrosion inhibiter to the interior (12) of supply pipe via lead portion (13). An independent claim is included for system for protection of metallic components and motor vehicle body. |
