| 摘要 |
The invention relates to a device for preventing overfilling of a plurality of fuel tanks ( 8 ) at a gasoline station, in the event that fuel tanks are filled simultaneously by multi-chamber tank vehicles ( 7 ). The fuel tanks ( 8 ) are equipped with filling level threshold indicators ( 3 ) linked to a transmitter ( 1 ) for wireless transmission of a signal. A receiver ( 2 ) mounted in the tank vehicle ( 7 ) is provided to control one or several tank valves. In order to ensure safe closure of the tank valves, the filling level threshold indicators ( 3 ) of the fuel tanks ( 8 ) at the gasoline station are connected each to a signal line ( 5 ) leading to a common interface ( 4 ). Only one transmitter ( 1 ) along with an interrogation control device is provided for connecting to said interface ( 4 ) and cooperates with the receiver ( 2 ) mounted in the tank vehicle ( 7 ). The receiver is connected to a control for receiving address-coded signals from the transmitter ( 1 ), said control being connected to an actuating device for selectively disconnecting the tank valves of the tank vehicle ( 7 ).
