Abstract

Damping hose (3) which is intended for introduction into a water pipe, in particular a connection pipe to a water tap, and in the case of which outer sealing flanges (1) and a yielding wall (2) are provided, said walls being connected to the flanges in a sealing manner and delimiting an air pocket C. The yielding wall of the hose has, in the absence of a water pressure, a pronounced convex form which affects essentially its entire extent and causes a narrow through-passage which is small in comparison with that which is required when a pressure prevails. Under operating pressure, the air in the air chamber is compressed and the yielding wall becomes approximately cylindrical, while the narrow through-passage widens and becomes large enough to permit the liquid flow to pass through it. The configuration of the hose ensures an increased damping effect of the air chamber and a reduced disruption of the water flow through the damping hose.
