<p>The separate coupling is for the transmission of fluid under pressure and comprises a connecting support and a lock cap. The lock cap is movable in relation to the support. A lock part is arranged in the coupling, which comprises a bush with an external thread for screwing into the connecting support. The bush has a central through hole in which a spring-loaded plunger can be moved. The plunger, when there is pressure through the coupling, can extend out of the bush hole. - As soon as pressure in the coupling is removed, the plunger returns into the bush hole, after which the lock cap can be moved, releasing a nipple.</p> |
