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 annula
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.

A device for damping pressure surges in pipelines for liquid, comprising a housing (1, 5, 6; 1, 20; 1, 34′, 44; 2, 3, 51, 52; 2, 3; 60, 61) with two pipe connection members (2, 3; 2, 81) and a space (8; 27; 49) in communication therewith wherein at least one elastically compressible means (16; 24, 2
A device for damping pressure surges in pipelines for liquid, comprising a housing (1, 5, 6; 1, 20; 1, 34′, 44; 2, 3, 51, 52; 2, 3; 60, 61) with two pipe connection members (2, 3; 2, 81) and a space (8; 27; 49) in communication therewith wherein at least one elastically compressible means (16; 24, 25; 32, 33; 39, 47; 57-59; 66, 67) is arranged for damping pressure surges in liquid in said space and pipelines adapted to be connected to the housing, said elastically compressible means having an elastic or flexible member (66, 67) surrounding at least a part of a sealed chamber filled with a pressurized gas, said elastic or flexible member (66) being covered at least on the side facing the sealed chamber with a pliable metal foil (67), and said pliable metal foil (67) extending in a leakproof arrangement over the whole elastic or flexible member (66) and being so thin that it has practically no adverse effect on the deformability of said elastic or flexible member (66) in order to prevent diffusion of the pressurized gas through the elastic or flexible member (66) out of the sealed chamber thereby ensuring a long-term maintenance of the gas pressure in said sealed chamber.
