Abstract

A liquid gas system for mobile applications includes at least one remote gas switch that is mountable to a bottle of liquid gas and a gas pressure regulator. The high-pressure input of the gas pressure regulator is connected to the remote gas switch. A distribution block is provided, the input of which is connected to the low-pressure output of the gas pressure regulator. A filter unit is arranged between the low-pressure output of the gas pressure regulator and the distribution block. Further, an electronic controller is provided which is connected to the remote gas switch.

First claim

The invention claimed is:

1. A liquid gas system for mobile applications comprising at least one remote gas switch that is mountable to a bottle of liquid gas, a gas pressure regulator, where the high-pressure input thereof is connected to the remote gas switch, a distribution block, where the input thereof is connected to the low-pressure output of the gas pressure regulator, a filter unit arranged between the low-pressure output of the gas pressure regulator and the distribution block, and an electronic controller which is connected to the remote gas switch.

2. The liquid gas system of claim 1 wherein the filter unit comprises a disposable filter.

3. The liquid gas system of claim 2 wherein the disposable filter is a filter cartridge.

4. The liquid gas system of claim 2 wherein a sensor for detecting the contamination of the disposable filter is provided.

5. The liquid gas system of claim 4 wherein the contamination sensor comprises a RFID chip which is integrated with the disposable filter.

6. The liquid gas system of claim 4 wherein the contamination sensor is connected to the controller.

7. The liquid gas system of claim 1 wherein the filter unit is integrated with the distribution block.

8. The liquid gas system of claim 1 wherein a second high-pressure tube leading to the second remote gas switch is connected on the high-pressure side of the liquid gas system.

9. The liquid gas system of claim 8 wherein the two high-pressure tubes are connected to both inputs of the tee-piece, where the output thereof is connected to the high-pressure input of the gas pressure regulator.

10. The liquid gas system of claim 1 wherein an electronic crash sensor is provided, which is connected to the controller.

11. The liquid gas system of claim 1 wherein a crash signal interface is provided by means of which the liquid gas system is adapted to access the crash signal of vehicle-side crash sensor.

12. The liquid gas system of claim 1 wherein a heating element and a sensor are provided on the low-pressure side of the liquid gas system.

13. The liquid gas system of claim 12 wherein the sensor is a temperature sensor.

14. The liquid gas system of claim 13 wherein different cooling curves are stored in the controller and that the controller is adapted to compare a measured cooling curve with the stored cooling curves.

15. The liquid gas system of claim 1 wherein a filling level meter is provided.

16. The liquid gas system of claim 15 wherein the filling level meter is connected to the controller.

17. The liquid gas system of claim 1 wherein a heating device which is connected to the controller is provided at the gas pressure regulator.

18. The liquid gas system of claim 17 wherein a temperature sensor which is connected to the controller is associated with the heating device.

19. The liquid gas system of claim 1 wherein the filter unit comprises a near field communications interface.

20. The liquid gas system of claim 1 wherein the controller comprises a remote communications interface.

21. The liquid gas system of claim 1 wherein the remote gas switch is directly connected to the input of the gas pressure regulator.

22. The liquid gas system of claim 1 wherein the remote gas switch is connected to the input of the gas pressure regulator by means of a high-pressure tube.

23. The liquid gas system of claim 22 wherein the high-pressure tube contains a tube break protector.
