- the length of the flow tube 48 and by the number of disks 14 of the Disc arrangement 19 and the mutual spacing of these discs exhaust gas back pressure and volume are adjusted on the damper.
- FIGS. 7-9 show different variants of the in a simplified representation Invention similar to damper insert 1 of Figures 1-4.
- the damper insert generally designated 1c in FIG. 7, consists of essentially from an outer pipe section 53, which as expansion and Absorption tube corresponds to the expansion or absorption tube 7 and one Expansion space 54 forms, in which a section 2 "of the flow tube 2 corresponding flow tube 56 closed with a price bar 55 reaches in.
- This is arranged axially with the axis of the tube 53 a smaller compared to the inner diameter of the tube 53 Outside diameter and is with its right end not visible in Figure 7 in use, the damper insert 1c is connected to the manifold outlet.
- the tube 56 which forms a first chamber, is perforated on its circumference, i. H. provided with a plurality of openings 57.
- a further flow tube 58 is provided offset from the tube 56, which forms a second chamber, again coaxial with the axis of the tube 53 is arranged, one in comparison to the inner diameter of the tube 53 has a reduced outer diameter and on its tube 56 facing End is closed with a tapered section 59 (impact cone).
- the both ends 55 and 59 are spaced apart in the axial direction of the tube 53.
- the tube 58 is also perforated, i. H. it has a plurality of openings 60.
- the pipe 58 leads with its in FIG left end to a pane arrangement corresponding to the pane arrangement 19 19a, d. H. to the central opening 11 of this arrangement so that the exhaust gas from the Tube 58 through the openings 11 and the other, in the disks 14 of the Disc arrangement 19a provided openings 18 finally flowing through the slot-shaped outlets 17 formed on the periphery of the disk arrangement 19a can exit, as is already the case for the exit of the exhaust gas from the Flow pipe section 2 "of the damper insert 1 has been described.
- a peculiarity of the disk arrangement 19a is that additional to the central opening 11 about the axis L of the disk assembly 19a or the axis of the Pipe piece 58 distributed and radially outwards relative to the central openings 11 offset additional gas outlet openings 61 are provided, for one Gas flow from the formed between the outer tube 53 and the tube 58 and Annulus 62 also acting as an expansion chamber in the disk arrangement 19 or in the subspaces formed between the disks 14.
- an adjustment plate 63 which by a predetermined pivot angle about the axis L of the Disk assembly 19a is pivotable back and forth on its circumference protruding adjustment lever 64, are the additional gas passage openings 61 fully or partially lockable.
- the adjustment plate 63 has this Control openings 65, which in an extreme position of the adjustment plate 63 (FIG. 11) are congruent with one gas passage opening 61 and in the other Extreme position of the adjusting plate 63 (FIG. 12) in relation to each Gas passage openings 61 are offset such that the latter through the adjustment plate 63rd are completely closed, the intermediate positions Gas passage openings 61 are partially open.
- the exhaust gas flow in the damper insert 1c is therefore independent of the position the adjustment plate 63 from the chamber formed by the tube 58 through the internal gas passage opening 11 in the disk assembly 19a.
- this first exhaust gas flow is a further exhaust gas flow into the disk arrangement 19a possible, namely from the annular space 62 through the outer passage openings 61, this second gas flow can be adjusted by adjusting the adjustment plate 63 can and in particular also the sound and the exhaust back pressure of the with the Exhaust system provided with damper insert 1c.
- the adjustment plate 63 is adjusted after the bolts 15 have been loosened possible. After tightening these bolts, the adjustment plate 63 is in her fixed each setting.
- the damper insert is 1c as well the disk assembly 19a in turn received in the outer pot, which in the Figure 10 is designated 20c and is designed so that the handle 64 is accessible remains.
- FIG. 8 shows a further possible variant of a damping insert 1d differs from the damping insert 1c in that instead of the Manifold outlet connected or to be connected pipe section 56 a Pipe piece arrangement 66 is provided, which consists of the two pipe pieces 67 and 68 consists of which the pipe section 67 with its not visible in Figure 8 right end in use is connected to the manifold outlet.
- the pipe section 67 is also at its left end visible in FIG provide at least one opening, d. H. the pipe section 67 ends at this end a closed subspace 59 formed in the tube 53.
- the further tube section 68 which is open at both ends opens into part space 69 at one end (Expansion space) and with its other, open end over a conical one Extension 70 into the expansion space 54 formed in the tube 53, in which then also the pipe section 58 is arranged. With the extension 70 the subspace 69 is Expansion space 54 is tightly sealed.
- the two pipe sections 67 and 68 are continue to overlap with their ends and continue with theirs Longitudinal extension relative to the longitudinal axis of the tube 53 so that the over the pipe section 57 supplied gas flow from this pipe section 67 into the subspace 69 occurs, then reversing the direction of flow from the subspace 69 in the Pipe piece 68 enters and finally passes through this into expansion space 54, where the gas stream then enters the pipe section 58 via the openings 61 and from this through the central openings 11 in the disc assembly 19a or at corresponding position of the adjusting plate 63 also from the annular space 62 through the outer openings 61 in the disk assembly 19a.
- the pipe section 58 is in this Embodiment not by the tapered section 59, but by a flat baffle plate 72 closed.
- FIG. 9 shows a greatly reduced partial representation as further possible ones Variant a damping insert 1e, which in the tube 53 for supplying the exhaust gas, for example the pipe section 56 or the one acting as a reflection damper Has pipe section arrangement 66 and in which the pipe section 58 for feeding the Exhaust gas to the central opening 11 at its disc assembly 19a opposite side is closed by a curved baffle plate 73.
- a damping insert 1e which in the tube 53 for supplying the exhaust gas, for example the pipe section 56 or the one acting as a reflection damper Has pipe section arrangement 66 and in which the pipe section 58 for feeding the Exhaust gas to the central opening 11 at its disc assembly 19a opposite side is closed by a curved baffle plate 73.
