退して両弁口２５．６３を共に開口する（第２図）。In the connection state between the socket 55 and the plug 60,
When compressed air is forced into the second through hole 7 of the socket 55,
The movable cylinder 21 moves forward against the elastic force of the first and second springs 32 and 36, and the valve rod 31 protruding forward of the valve body 29 abuts against the valve body 64 of the plug 60, and at this time, the valve body 29 and the valve body 64, since the springs 30.66 have the same strength, move back from each other and open both valve ports 25.63 together (FIG. 2).

この場合、作動筒３５の先端面にはシールリング３７を
取付けられているので、この作動筒３５とプラグ６０と
の突合部分はシールされている。In this case, since a seal ring 37 is attached to the distal end surface of the actuating cylinder 35, the abutting portion between the actuating cylinder 35 and the plug 60 is sealed.

また、可動筒２１が第２作動室９内を前進するときには
、同室９に設けた排気孔５から空気が排出されるので、
当該可動筒２１はスムーズに前進する。Furthermore, when the movable cylinder 21 moves forward within the second working chamber 9, air is exhausted from the exhaust hole 5 provided in the second working chamber 9.
The movable cylinder 21 moves forward smoothly.

第２通孔７からの圧縮空気の供給を停止すると、可動筒

よって復動し、それに伴ってプラグ６０側の弁体６４も
ばね６６の弾発力によって復動して、弁口２５．６３を
共に閉塞する。When the supply of compressed air from the second through hole 7 is stopped, the movable cylinder 21 moves back due to the elastic force of the first and second springs 32 and 36, so that the valve body 29 on the socket 55 side is moved by the elastic force of the spring 30. Accordingly, the valve body 64 on the plug 60 side also moves back due to the elastic force of the spring 66, thereby closing the valve ports 25 and 63 together.

次に、プラグ６０をソケット５５から外す場合について
説明する。Next, a case in which the plug 60 is removed from the socket 55 will be described.

第１通孔６から圧縮空気を第１作動室８内に供給すると

できるようになって、プラグ６０の嵌合溝６２から外れ
、その結果、プラグ６０は第２ばね３６と第３ばね３９
の弾発力により、ソケット５５外に押し出される。When the locking body mounting cylinder 42 retreats in this manner, the locking body 49 is loosely fitted into the tapered hole 46...
Since the restraining force of the inclined surface 11 provided at the opening 10 of the ring cylinder 12 against the ring tube 12 becomes weaker, the locking body 49 becomes able to move in the radial direction and comes off from the fitting groove 62 of the plug 60, and its As a result, the plug 60 has the second spring 36 and the third spring 39
It is pushed out of the socket 55 by the elastic force of.

この場合、第４ばね４３の弾発力よりも第２ばね３６の
弾発力の方が強いので、可動筒体３８の先端薄肉筒４１
は施錠体装着筒４２の内周に向けて進入してテーパ一孔
４６・・・内の施錠体４９・・・を半径方向に押圧し、
プラグ６０の次の接続に備える。In this case, since the elastic force of the second spring 36 is stronger than the elastic force of the fourth spring 43, the tip thin-walled cylinder 41 of the movable cylinder 38
enters toward the inner periphery of the lock body mounting cylinder 42 and presses the lock body 49 in the tapered hole 46 in the radial direction,
Prepare for the next connection of the plug 60.
