Patent ID: 7874319

Claim:
A pipe for carrying gas and/or fluid, having a supporting body ( 2 ) which consists of a relatively rigid first plastic and has one recess ( 6 ) or multiple recesses ( 6 ) which pass through the supporting body ( 2 ) across the longitudinal direction ( 7 ) and are arranged so that the supporting body ( 2 ) is flexible in a longitudinal section ( 8 ) that is provided with the recess ( 6 ) or the recesses ( 6 ) and withstands compressive forces acting on the inside and/or outside of the pipe ( 1 ) during use of said pipe, having a membrane ( 3 ) consisting of a relatively soft flexible second plastic arranged on the supporting body ( 2 ) so that it seals the recess ( 6 ) or recesses ( 6 ) and transmits the compressive forces acting on the membrane ( 3 ) during use of the pipe ( 1 ) to the supporting body ( 2 ), the membrane ( 3 ) is integrally molded on the supporting body ( 2 ) or vice versa, wherein, the membrane ( 3 ) sheaths the supporting body ( 2 ) completely on the inside and/or outside at least in the area of the flexible longitudinal section, the pipe ( 1 ) has two end sections ( 13 , 14 ) designed as connections, each section being formed by a section ( 15 , 16 ) of the supporting body ( 2 ) that is closed on the circumference, with at least one flexible longitudinal section ( 8 ) of the supporting body ( 2 ) being arranged between them; wherein the recesses ( 6 ) are arranged in the flexible longitudinal section ( 8 ) of the supporting body ( 2 ) so that the supporting body ( 2 ) remaining in the flexible longitudinal section ( 8 ) has rings ( 9 ) arranged coaxially with the longitudinal direction ( 7 ) of the pipe ( 1 ) and side-by-side in the longitudinal direction, adjacent rings ( 9 ) are joined together by only two webs ( 10 ) that are diametrically opposed, with each ring ( 9 ) that is arranged between two neighboring rings ( 9 ), the only two webs ( 10 ) that are connected to the one neighboring ring ( 9 ) are arranged so they are offset by 90° with respect to the only two webs ( 10 ) connected to the other neighboring ring ( 9 ).
