Abstract

The hose (1) covering (3) is generally cylindrical, and consists of a woven wire mesh bag with tapered ends with connecting rings (1.3,1.4). There is a circumferential ring or bulge (3.1) to provide a reserve to accommodate increases in length. There is a flexible metal bellows (2) inside the bag, with ring-shaped crests (2.1) and valleys (2.2).
