A plug-type coupler consisting of male part (P) and female part (M), particularly for the connecting of conduits (2, 3) conducting fluids (4), which coupling has, within the region of the abutment place (1) between male part (P) and female part (M), a metallic ring packing (D) which is expandable in its cross section as a result of its arrangement and of a surface slot (18) by fluid (4) which is under pressure and, in this connection, rests in part on the male part (P) and in part on the female part (M), and, in order to obtain a solution which is simple in manufacture and reliable in use, the ring packing (D) which is arranged on the male part (P), with its slot (17) facing radially inward is gripped over, on the other side of the slot edge lying in the insertion direction (arrow x) by an annular shoulder (24) from which there extends a frustoconical surface (25) which tapers down towards the axis (y--y) of the plug-type coupler and opposite which there is a mating surface (27) of the female part (M) which extends into an abutment surface (14) which urges the ring packing (D) in insertion direction (x), the frustoconical surface (25) and the mating surface (27) permitting the passage of fluid up to the ring packing (D).

Plug-type coupler

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.
