Problems solved by technology

[0007] However, when a quick connect / disconnect type coupling is used at the junction between the fuel container and the fuel cartridge, metal ions may detach from the metal components in the valve element and enter pure methanol, causing degradation of the electrode membrane structure

[0057] Figures 2 and 3 depict a first embodiment of the coupling of the present invention. Wherein, Fig. 2 shows the state of the coupling before it is assembled, and Fig. 3 shows the state of the coupling after it is assembled. This coupling can be used on passive fuel cells for coupling a fuel cartridge to a fuel container mounted on the fuel cell body.

[0058] In these figures, 10 denotes the nozzle, 20 denotes the socket, 11 denotes the nozzle body, 12 denotes the nozzle head, 13 denotes the nozzle outlet, 14 denotes the movable pin, 15 denotes the first supporting member, 21 denotes the housing, 22 is an annular flange, 23 is a sleeve, 24 is an annular gasket, 25 is a valve stem, 26 is a valve head, and 27 is a second supporting member.

[0059] This coupling consists of a nozzle 10 and a socket 20 . The nozzle 10 is designed to be connected to the mouth of the bottle-shaped fuel cylinder 1 , and the socket 20 is designed to be connected to the inlet 2 of the fuel cont...

[0075] 5 and 6 show another embodiment of the coupling of the present invention. Wherein Fig. 5 shows the coupling is in its state before assembly, and Fig. 6 shows the coupling is in its state after assembly. In FIGS. 5 and 6, 31 denotes a nozzle body, 33 is a nozzle opening, and 34 is an elastic ball.

[0076] This example differs from the above example shown in FIGS. 2 and 3 mainly in that the movable pin 14 and the first support member 15 of the previous example are replaced by elastic balls 34 in this example. As for the configuration of the socket 20 in this example, it is basically the same as in the previous example. Therefore, the same parts as those in the previous example are given the same reference numerals in this example, and thus their explanations are also omitted.

[0077] In this example, the main part of the nozzle 10 is constituted by the nozzle body 31 and the elastic ball 34 . The distal end of the nozzle body 31 is provided with a nozzle opening 33 ....

Abstract

A coupler is constructed from a nozzle (10) and a socket (20). The nozzle (10) has a nozzle body (11), a movable pin (14), a first support member (15), etc. The movable pin (14) can advance and retreat in a nose section (12), in an axial direction, and opens and closes a flow path in the nozzle. The socket (20) has a housing (21), a collar (23), a ring-like packing (24), a valve stem (25), a valve head (26), a second support member (27), etc. The valve stem (25) can advance and retreat in the socket (20), in the axial direction, and opens and closes a flow path in the socket. Those portions in the coupler that come in contact with liquid fuel are each made only from rubber and / or plastic.

Description

technical field [0001] The present invention relates to a coupling consisting of a nozzle and a socket on which the nozzle is mounted, for supplying liquid from the nozzle to the socket. In particular, the present invention relates to a coupling designed to reconnectably couple a fuel cartridge to a fuel cell when replenishing the fuel container of a passive fuel cell with methanol in a fuel cartridge. container. Background technique [0002] In recent years, fuel cells have been widely used as a power source in various mobile devices, such as notebook computers, mobile communication phones, etc., so that such devices can be used for a longer period of time without having to recharge the power source . This fuel cell is characterized in that electric energy can be easily regenerated by supplying it with fuel and air, so it can continuously generate electric energy for a long period of time as long as it is supplied with fuel. Therefore, if the fuel cell can be miniaturize...
