20100200115 | GUIDE, FILL-ENABLING AND FILTERING DEVICE FOR A TANK, IN PARTICULAR FOR A TANK OF UREA SOLUTION FOR A MOTOR VEHICLE FITTED WITH A DIESEL ENGINE - The device comprises a hollow external body, operationally arranged in a filler of the tank and anchored in which, with the interpositioning of a permanent magnet, is an internal body which defines an essentially tubular passage. The arrangement is such that when the nozzle of a urea solution distributor pistol is inserted into the passage of the internal body, the magnet causes an opening of an on/off valve in the pistol, permitting the input of a flow of the said solution into the tank. The device also comprises a filter through which the urea solution is intended to pass. | 08-12-2010 |
