<P>PROBLEM TO BE SOLVED: To enable to connect or disconnect a cartridge safely without generating liquid leak, in injecting liquid fuel from a fuel cartridge into a fuel cell. <P>SOLUTION: An injection side valve 3 and a cartridge side valve 2 of the liquid injection device 1 of a fuel cell are provided with hollow parts 9, 16 as well as sockets 4, 11 insertion-coupled with each other at liquid injection, movable components 7, 14, and springs 8, 15. A convex part 4d and a concave part 4e penetrating the socket insertion-coupling face are provided at an insertion-coupling face of a socket, so that the convex part 4d of the cartridge side valve and the concave part 11e of the injection side valve as well as the concave part 4e of the cartridge side valve and the convex part 11d of the injection side valve are insertion-coupled with each other, respectively, and at the same time, pistons 7a, 14a penetrating the respective concave parts from inner faces of the sockets are provided at a movable component side, so that the valves are at an open state as the convex parts press the pistons in a socket inner face direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
