Benefits of technology

[0009]The present invention has been made in view of the above described problems and desires regarding the prior art and it is an object of the invention to provide a coupler in which the number of seal members is reduced and energizing force for energizing the valve can be maintained constant.

Problems solved by technology

In this type of coupler, seal members corresponding to the number of seal sections are required resulting in requirement for a large number of seal members and also a large number of processes for assembling.
There is another problem in this type of coupler.

Embodiment Construction

[0043]Description will be made about embodiments of the invention with reference to the accompanying drawings.

[0044]Description will be first made about the entire construction of the coupler of the invention taking, by way of example, a case where the coupler is applied for coupling a fuel cell main body and a cartridge main body for supplying fuel.

[0045]FIG. 1A shows a vertical section of a socket and a plug constituting a coupler of the invention in a case where the coupler is applied to a fuel cell in which the socket is separated from the plug and FIG. 1B shows a bottom view of the socket.

[0046]This coupler 10 for a fuel cell (hereinafter simply referred to as “coupler”) is made of a socket S10 and a plug P10 which is fitted and coupled with this socket S10. The socket S10 is provided, for example, in a fuel tank which constitutes a container main body of a methanol fuel cell and the plug P10 is provided in a bottle which constitutes a container main body of a cartridge main bo...

Abstract

A couple 10 includes a valve seal member 71 (36) provided in a flow path between a valve 35 and a coupler main body 31 which can be opened and closed, and a container-inside-outside seal member (73) which is used as both a container seal member (73) for forming a seal between the container main body 31 and a valve holder 38 and a holder seal member (73) for forming a seal between the coupler main body 31 and the valve holder 38. By this arrangement, the number of the seal members can be reduced, processes for assembling can be simplified and the manufacturing cost can be saved. Mounting position of the holder 38 can be controlled by a mounting position control section 74 to enable sealing for maintaining energizing force by energizing means 39 constant and ensuring opening of the coupler as well as for securing the sealed state accurately.

Description

TECHNICAL FIELD[0001]This invention relates to a coupler comprising a pair of a socket and a plug which are detachably fitted and coupled to each other and used for pouring liquid or the like from a container main body such as a bottle on a cartridge side to a container main body such as a tank on a device side or exchanging a container main body. More particularly, the invention relates to a coupler of this type in which the number of seal members can be reduced and which is particularly useful as a coupler between a cartridge type container for a methanol fuel cell and a main body of the fuel cell.BACKGROUND ART[0002]Various liquid type fuel cells which can generate electricity directly from a liquid fuel have recently been developed. Attention has been paid to using a direct methanol fuel cell (DMFC) using methanol as a fuel as a power source of portable type electronic devices because it does not require a reformer and hence it can be made in a compact design.[0003]Particularly,...
