Hose, particularly plunger medium pressure hose of different structures, for conveying pressurised fluid, particularly air, between pressure-reducing valve and automatic breathe controller of diving apparatus, is formed from inner hose

摘要

The hose (1) is formed from an inner hose (3) made of rubber, a reinforcement layer (4) is applied on it, and a polymer coating (2). A hose section of approx. 80cm length of the hose has a vertical expansion of 80 percent of its stretched length, after heating at a temperature of more than 80 degree celsius in a z-shaped forced fixation, cooling of the hose section at room temperature in the forced fixation, and releasing of the hose section from the forced fixation with the vertical hanging of the hose section at an end.
