ABSTRACT:
A connecting coupling (K) or separating device for conduits or for detachable conduit connection of, in particular, pressure-conducting fluid conduits (I, II), having a first coupling part (I) and a second coupling part (II), a closed fluid flow path being present in coupled state, in which connection further radial conduit sections of a coupling connection conduit and of a coupling part have mouth cross sections which can be brought into coincidence and, in the course of the coupling process, a coupling closure in each coupling part (I, II) can be opened and the mouth cross sections both of the coupling connection conduit and of the radial conduit section of the coupling part can be closed by displacement, the displacement at the same time bringing about the valve closure of the first and second coupling parts (I, II). In order to achieve a compression-free coupling with the least possible leakage or possibility of leakage, a closure part (V) which performs the slide function forms a conduit section (11) of the fluid flow path and, in the course of the displacement, the conduit section (I) can be isolated, with enclosure of the part of the fluid present therein.
