<p>PURPOSE: To connect both joint nozzles reasonably, and to eliminate the remaining pressure of a residual fluid in both joint nozzles. CONSTITUTION: At the front end in the first nozzle main body 2 of the first joint nozzle 1, the first valve hole 13 opened and closed by a fixed valve rod 8 is provided, a movable valve seat 12 pressed to the second joint nozzle 4 side is combined movable in the axial direction, while a fixed valve seat 20 having the second valve hole 21 which is opened and closed by a movable valve rod 18 pressed to the first joint nozzle 1 side, and movable in the axial direction, is formed to the base end of the nozzle main body 5 of the second joint nozzle 4. When the second nozzle main body 5 moves to the first joint nozzle 1 side, the movable valve rod 18 hits the fixed valve rod 8, so as to block its movement, it moves to the first joint nozzle 1 side together with the movable valve rod 12 from the time when the fixed valve seat 20 hits the movable valve seat 12, to the time when the movable valve seat 12 moves to the moving end, and the first valve hole 13 and the second valve hole 21 are opened so as to open both link passages 3 and 6.</p> |
