ABSTRACT:
An annular chamber (8) is formed between a pipeline section (1) and a housing (5, 6) surrounding same. This annular chamber is in communication, via openings (10, 11) in the wall of the pipeline section (1), with the interior (12) of the latter. An air-filled hose ring (16) is arranged in the annular chamber (8). The device damps the pressure surges occurring in domestic installations on account of the rapid closing of quick shutoff elements, for example lever mixers. The danger of damage to the pipelines and fittings is thereby avoided.
