Abstract (en)

[origin: WO9935431A1] The invention relates to a connection between a first pipe piece (1) and a second pipe piece (8), wherein the cross section of both pipe pieces is substantially equal, wherein the connection allows at least a mutual angular displacement of the axis of both pipe pieces in a plane extending through both axes, wherein the first pipe piece comprises at least two passages (3, 2) and the second pipe piece comprises at least two passages, and in any mutual position of the pipe pieces the separating walls (10) between the passages in the first pipe piece at least practically make contact with the separating walls between the passages in the second pipe piece, wherein both pipe pieces have a round cross section and wherein the boundary surface between the pipe pieces extends substantially as a sphere with the point of rotation of the pipe pieces as centre. According to a first preferred embodiment the second pipe is provided with a number of passages larger than two. The advantages of the present invention are also achieved in this situation, i.e a separation between both passages in the first pipe piece.
