Definitions
- the invention relates to a flange connection of two pipes, in particular the pipes of an exhaust system of a motor vehicle internal combustion engine according to the preamble of patent claim 1.
- Such a flange connection is known for example from DE 44 44 550 AI.
- the invention is concerned with the problem of making a generic flange connection as efficient as possible and easy to assemble while at the same time having a technically perfect function.
- FIG. 2 is a side view of the pipe flange connection of FIG. 1,
- FIG. 3 shows a section of the pipe-flange connection in FIG. 1
- a first flange 2 is molded onto a first tube 1 as a radially outwardly projecting annular fold, from which a first connecting tube section 3 runs freely centrally to the axis of this flange 2.
- a spring clip 8 which is attached to the two tubes and axially tensioningly engages the flanges 2 and 5, ensures that the flange connection is closed.
- the second flange 5 including a short adjacent tube area, is radially enlarged on the inside, so that the first connecting tube section 3, which is dimensioned with respect to its axial length, can engage in this enlarged area in order to achieve mutual centering.
- Fig. 5 is a freely axially expiring second connecting tube portion 9 is formed on the second flange 5 which is radially designed as guides for the other two, already described from ⁇ inner diameter moderately in the same manner.
- the mutual centering of the two flanges 2, 5 takes place here by inserting the first into the second connecting pipe section 3 or 9 Sealing ring 7 lies between the two flanges 2, 5 on the outer circumference of the second connecting pipe section 9.
