<p>The coupling has fluid input and outputs (4). Inside it is a fixed locking pin (5) to act with movable tubular elements (7,9) against springs (8,10). A screw-shaped coupling (3) can be inserted in the nut-shaped part (2). The coupling has a cylindrical projection (40) and an aperture (4) to let out the fluid under pressure, and a seal (17) on the inside. Inside the screw-shaped element there is a movable tubular element (15). This has a closed end (14) against which one of the springs lies. The spring is on a fixed support (11). The tubular element (15) has an external swelling (16) round it, which in the rest position is against an annular stop (17). <IMAGE></p> |
