Hose line for passing liquid or gases under pressure, has annularly corrugated or helically corrugated metal hose and outer surrounded hose braid which is braided from wires made from metal, ceramic or plastic

摘要

The hose line (1) has an annularly corrugated or helically corrugated metal hose (2) and an outer surrounded hose braid (3) which is braided from wires made from metal, ceramic or plastic and serves for increasing the pressure resistance of the hose line. The hose braid is applied on the metal hose such that a frictional force in a central area (5) of the hose line is smaller than in one of the both end areas (6,7). The frictional force directly or indirectly acts between the metal hose and the hose braid.
