      Plug-in coupling for pressure pipes The subject of the present invention is a plug-in coupling for pressure pipes, which is characterized in that one of the coaxially arranged pipe ends to be connected with its opposite ends: sleeve enclosing the two pipe ends from one another;

  distancing constriction belt as well as two, spaced apart from; this belt, tapered bulges; in which rubber rings are inserted, which practically do not prevent the insertion of the pipe ends into the sleeve, but prevent the pipes from exiting by wedge action Act.



  In the drawing, an exemplary embodiment, a plug coupling according to the invention, is shown. It shows: Fig. 1 an axial section through the Steckkupp ment front commissioning and Fi, g. 2 an axial section: through the plug-in coupling after the same start-up.



  In the drawing, h denotes a sleeve into which the two ends of the coaxially arranged tubes f and g, which are to be coupled together, are inserted from opposite sides:

  are. In its center, the sleeve h has a constriction belt <I> i, </I> which slightly distances the ends of the tubes f and g from one another in the middle of the sleeve. At the ends: of the sleeve h: and thus spaced apart from the constriction belt i;

  on the sleeve two conical bulges k and s which taper away from the sleeve and which, with the tubes f: and g inserted in @die, sleeve h, form two conical curves t and v.

   Rubber rings <I> m </I> and <I> n </I> with a circular profile cross-section are inserted into these; chambers; their diameter; exceeds that of the inserted: tubes f and g, so that these rings <I> m </I> and <I> n </I>;

  inserting the tubes f and g into the sleeve h @ through the respective opening of the rings <I> m </I>; or. <I> n </I> not noticeably hindering. The rings <I> m </I> and n are: by a shoulder at the beginning of the conical bulge k and s .am:

  Penetration into the sleeve h prevented.



       If the flow of water z. E.. In the direction of ider; arrows P through the plug-in coupling shown, the pipe f below;

  seeks to remove the effect of the water pressure from the pipe g, it is possible for it to do so by the distance x + z (Fig. 2), with the ring <I> m </I> in the narrower part of the chamber <I> t </I> is pressed,

       as far as it allows its deformation occurring under breath prevailing pressure.

         While the ring m; moves towards the position marked m 'in Fig. 2, the displacement of the tube f results in:

  with respect to the sleeve <I> h </I>, an increasing force through which, with the now occurring relative displacement z, between the sleeve <I> h </I> and the tube g also the rubber ring <I> n </I> is deformed (n ').

       In the position of the parts shown in FIG. 2, which can also be achieved by suddenly tugging the tubes inserted into the sleeve apart, the coupling can, as a result of the wedge effect of the rings <I> m </I> and <I> n </I> can no longer be resolved.
