| Abstract: |
A recreational vehicle safety system includes two independently operable automatic shutoff valve assemblies. One valve assembly is attached directly to the recreational vehicle's appliance high-pressure fuel tank in such a manner as to be operable in all conceivable crash situations, and the other is connected downstream from the appliance fuel line's high-pressure regulator and is designed to close off the fuel flow when a fuel line breaks or small gas leaks are present, such as when an appliance pilot light goes out. Provided also with these valve assemblies are a gas sensor and warning light and audible alarms located about the recreational vehicle to alert campers to potentially dangerous malfunctions. Electrical and manual resets are provided for the safety system, so that the recreational vehicle's appliances can be made operable again if a malfunction occurs in the wilderness, remote from needed tools and expert mechanical assistance.

First Claim:
Show all 27 claims |
Therefore, in light of the above detailed description of the preferred embodiment, I claim:
1. In a recreational vehicle having a cabin, at least one appliance, a high-pressure fuel tank to supply fuel to said appliance, a fuel line interconnecting the fuel tank with said appliance and a high-pressure regulator located in the fuel line between the fuel tank and said appliance the improvement including a safety system comprising;
- a first automatic valve means coupled directly to said high-pressure fuel tank for shutting off the flow of fuel from said high-pressure fuel tank when a predetermined drop in fuel pressure occurs downstream from said first automatic valve means;
- a second automatic valve means coupled to said fuel line downstream from said high-pressure regulator for shutting off the flow of fuel in said fuel line when a predetermined pressure differential occurs across said second automatic valve member;
- electrical means for resetting said second automatic valve means, and
- means for indicating when said second automatic valve means has shut off the flow of fuel in said fuel line.
