- the metal coil spring 1 2 5 moves the upper seal part 1 2 4 c of the biston pulp 1 2 4 and the lower seal part 1 2 4 d, but the upper seal part of the piston pulp 1 2 4 1 2 4 c and lower sealing part 1 2 4 d Sealed in the space 1 2 6, so that liquid such as methanol flowing in the flow path of 1 2 4 e Is completely sealed.
- the spring is located in the space 1 2 6 sealed by the upper seat portion 1 2 4 c and the lower seal portion 1 2 4 d of the biston valve 1 2 4. If the locking part 1 2 4 f moves back and forth while contacting the inner circumference of the large-diameter cylindrical part 1 2 2 b of the Bragg body 1.21, the spring locking part 1 2 4 f moves to the space 1 2 As the volume above and below 6 changes, the pressure changes.
- this pressure change causes the upper and lower seal parts 1 2 4 c and 1 2 4 d to break, and a liquid such as methanol is sucked from the flow path 1 2 4 e etc. in a negative pressure state.
- the liquid such as methanol sucked into the space 1 2 6 is pushed out to the flow path 1 2 4 e and the metal flowing into the flow path 1 2 4 e may be mixed.
- the plug P 1 1 0 of this coupler 1 1 0 has a plug arm as a mating side of the connection holding means 1 1 8 that holds the plug body 1 2 1 and the socket S 1 1 0 in a connected state.
- 1 2 7 is provided, for example, by forming hooks 1 2 7 a on the inner sides of the two lock arms 1 2 7.
- the locking groove 1 1 9 as one of the connecting and holding means 1 1 8 formed on a member that is attached to the fuel cell main body F as described above or as a separate body, for example, about 30 degrees
- a circular arc-shaped groove of the range is provided opposite to the center axis, and the locking portion 1 1 2 k is provided at half of the diagonal position of the socket body 1 1 2 protruding into the locking groove 1 1 9
- the hook is locked with this locking part 1 1 2 k, so that the hook can be opened at the part without the step part, and it is operated in combination with axial insertion / removal and rotation Insert this hook 1 2 7 a into the locking groove 1 1 9 and insert the half of the diagonal position of the locking groove 1 1 9 PT / JP2005 / 023839
- socket body 1 12 Locking part 1 12 Rotate and lock to 12 k to hold the connected state, so that hook 127 a is returned to the part without locking part 1 12 k It can be opened by rotating and pulling out.
- a container B (not shown) is screwed into the container B in which the plug P I 10 is provided, and can be sealed with, for example, a packing attached to the inner top surface of the cover cap.
- the coupler 1 10 constituted by such a socket S 1 10 and the plug P 1 10
- the O-ring 1 14 on the outer periphery of the small-diameter cylindrical portion 12 1 c of the plug body 121 a is in contact with the inner peripheral surface of the inner diameter part 1 12 j of the plug mounting part 1 1 2 h of the socket body 112, and in the initial connection state, the operation part 1 15 b of the socket S 1 10
- the plug P 110 piston pulp 1 24 operation recess 124 b is not pushed down, the socket 1 1 5 a is seated on the seal 11 2 c in socket S 1 10, and the valve P 124 is plug 124 a The closed state where the valve seated on the seal portion 121 e is maintained.
- the operation part 1 15 b of the socket S 1 10 and the operation recess 12 4 b of the piston valve 124 of the plug P 1 10 come into contact with each other and push back each other.
- the valve parts 1 15 a and 1 24 a of the socket valves 1 15 and 1 24 of the socket S 1 10 and the plug P 1 10 are separated from the seal parts 1 1 2 c and 121 e, and the communication state is established.
- the opening order of the valves can be set by adjusting the spring force. For example, the socket S1 10 side of the main body etc. is opened first, and the plug P1 1 0 side of the container etc. is opened later. It can also be done.
- the fitting connection state of the plug P 1 10 and the socket S 1 10 is the connection holding means 1 18 on one side of the mouthpiece groove 1 19 in the socket body 1 19 and the locking portion 112 of the socket body 1 12.
- the hook 1 2 7 a of the lock arm 1 2 7 on the other side is inserted into k and can be held by turning and locking.
- Methanol can be replenished by returning to the container side, or the entire container can be replaced.
- this coupler 110 As described above in detail, according to this coupler 110, the following conditions necessary as a coupler provided between the methanol fuel cell main body and the methanol container for fuel are satisfied.
- the present invention can be used as a coupler that allows liquid or the like to be easily transferred from a container to a container on the main body side or exchanged with the container, and is particularly provided between a cartridge container of a methanol fuel cell and a fuel cell body And suitable.
