Recreational vehicle safety system

In a recreational vehicle having a housing, at least one appliance, a fuel tank to supply fuel to said appliance, a fuel line interconnecting the fuel tank with said appliance, and a pressure regulator connector to the fuel line, the improvement comprising a recreation vehicle safety system having;

• a smoke and gas detector mounted inside the housing of the recreational vehicle for indicating the presence of at least one of a gas or smoke condition within the housing, and
• means operatively connected to the smoke and gas detector, to shut off the flow of fuel in said fuel line when said smoke and gas detector indicates the presence of a predetermined amount of an oxidizable gas in the recreation vehicle including an electrical power source operatively connected to the smoke and gas detector so that the said detector electrically signals the presence of a predetermined amount of an oxidizable gas and wherein the means to shut off the flow of fuel further includes a valve assembly having;
• a housing member with an interior passageway interconnected to said fuel line;
• a valve seat through which the fuel must flow mounted in the interior of said housing member;
• a valve member mounted in the interior of said housing member and upstream from said valve seat;
• means for biasing said valve member to an open position upstream from said valve seat including a first solenoid assembly operatively connected with said valve member and electrically connected with said smoke and gas detector and said power source such that when said smoke and gas detector signals the presence of an oxidizable gas, said first solenoid is actuated so that said valve member closes against said valve seat, thereby shutting off the flow of fuel in said fuel line, and
• means to permit said valve member to be closed against said valve seat when a predetermined pressure differential develops between the upstream and downstream ends of said housing member.

• a shaft mounted in the wall of said housing member;
• a nonconducting pin movably mounted in said shaft such that a first end extends into said interior passageway so that said valve member contacts the first end of said pin and forces it radially outward along said shaft;
• a flexible diaphragm connected to the nonconducting pin;
• a metallic coating affixed to a side of said diaphragm and providing electrical contact with said housing member, and
• an adjustable conducting pin mounted above said diaphragm such that when said valve member forces said nonconducting pin radially outward, said pin forces said diaphragm radially outward to contact said conducting pin, thereby bringing said housing member into electrical contact with said conducting pin to indicate the closing of the valve member.

A safety system for the detection of gases and the control of fuel from a supply source of the type used in recreational vehicles, comprising:

• a smoke and gas detector capable of being mounted inside the housing of the recreational vehicle for indicating the presence of at least one of a gas or smoke condition within the housing with a first electrical signal;
• valve means operatively connected to the smoke and gas detector, to shut off the flow of fuel in said fuel line in response to said first electrical signal from said smoke and gas detector indicating the presence of a predetermined amount of an oxidizable gas in the recreational vehicle;
• pressure indicator means operatively connected to said valve means and to said fuel line to monitor and generate a second electrical signal indicative of the existence of fuel pressure beyond a predetermined limit, said valve means also responsive to said second electrical signal to shut off the flow of fuel and
• electrical means for resetting said valve means to a flow condition.
