ABSTRACT:
Valves for connecting fuel supplies to a device are disclosed. The fuel supplies can be a pressurized or non-pressurized cartridge that can be used with any device, such as fuel cells or fuel refilling apparatus. The valve includes face seals to minimize the amount of fuel remaining in the valve when the fuel supply is separated from the device. In one embodiment, the valve includes deformable members including sealing surfaces, where the flow paths through the valve are sealed and unsealed by the deformation of the deformable members. In another embodiment, the female valve component includes a shortened body to limit the volume of fuel remaining in the valve. The female valve component also includes a cap with slots formed therein so that residual fuel can drain from the valve component into a fuel reservoir.
