ABSTRACT:
The present invention is a safety system for a gas operated appliance in a vehicle. The system includes means for generating an electrical signal, such as a pre-determined voltage. The system also includes means for interrupting this electrical signal. One such means is a gas sensing means which is designed to interrupt the electrical signal in response to sensing gas. Another such means is an inertia switch means which interrupts the electrical signal in response to detecting a rapid changes in vehicle inertia or vehicle orientation. Yet another such means is a high temperature switch means which interrupts the electrical signal in response to detecting an elevated temperature in an area near said appliance. Finally, the system includes an emergency kill switch means for manually interrupting the electrical signal. The system further includes a fuel tank and a gas line between the fuel tank and the appliance. A valve means is used which is adapted to automatically and mechanically close to thereby stop the flow of gas through the gas line. Coupled with this valve means is a solenoid means designed to open the valve means in response to said electrical signal to therey allow the flow of gas through the gas line.
