Abstract

The existing problem is supplying fuel at a fixed flow rate to a fuel cell, and moreover, miniaturization of the device in which the fuel cell is loaded, in a fuel cartridge for a fuel cell. The fuel cartridge for a fuel cell 1 is equipped with a container main body 2 that is equipped with a connection part 22 that connects to the fuel cell, and houses the fuel F that is supplied to the fuel cell in its interior, and a push out means P for pushing out the fuel F, and a valve 4 that has a supply port 41a for supplying fuel to the fuel cell, and that opens the supply port 41a in response to the operation connecting the container main body 2 tothe fuel cell. On the connection part 22 there is provided a pressure regulating mechanism 5, one end of which communicates with the valve 4, and the other end of which communicates with the inside of the container main body 2, and that causes the fuel F that is housed in said interior to flow out to the valve 4, by regulating to a secondary pressure lower than the primary pressure inside the container main body 2.

Abstract

To equip a lighter with a valve structure that can be fitted easily without limiting the material to which it is fitted. [Means of Solution] The igniter provides a unit valve (10) that houses in order a spray nozzle (5), a valve mechanism part (4) and the flow volume adjustment mechanism (3) inside a metal valve main body 11 by causing one end of the spray nozzle (5) to protrude, and that is made into a unit by caulking the other end of said valve main body. The valve main body (11) has a guard part (113) for positioning that protrudes outwards in the vicinity of one end of the spray nozzle (5), and annular projections (114) for welding on the periphery of the other end from said guard part (113). While the valve main body (11) is inserted in the attachment opening (23a) that is formed on the upper wall of the tank (23) from the above-mentioned other end, the above-mentioned projections (114) are ultrasonically inserted in the inner face of the attachment opening (23a) and the unit valve (10) is fitted to the upper wall of the tank (23).

Abstract

Problem. To provide a liquid- fuel combustion appliance without a space between the combustion portion of the wick and the inner walls of the closure cap and with the formation of a stable flame. Means for the Solution of the Problem. A liquid- fuel combustion appliance (1) that comprises: an appliance body (2) having a fuel tank (21) that contains a liquid fuel; a combustion wick (3) for burning the fuel at the tip of the combustion portion (31) to which the fuel is delivered from the fuel tank (21) by capillary action; an ignition unit (4) for delivering sparks to the combustion portion (31); a closure cap (5) for closing and opening the upper part of the appliance body (2); and a through channel (22c) that connects the interior of the fuel tank (21) with the atmosphere. The closure cap has a closing member (53b) that closes or opens the combustion portion (31). The aforementioned closing member (53b) has a first seal (54) that comes into contact with the tip of the sleeve member (32) and closes the combustion portion (31) and a through-passage seal (55) that closes the through passage (22c).
