FIELD: personal use articles.SUBSTANCE: group of inventions relate to hoses for transporting fluid materials. The hose comprises an inner tube made of an elastic material, and an outer tube made of an inelastic material. The hose is automatically stretched in the longitudinal direction and in the transverse direction upon application of water pressure exceeding up to six times the value of the length in the unstretched or the compressed state. After removal of the water pressure inside the hose it is automatically compressed turning in a compressed state. The inner tube is located concentrically inside the outer tube both in the compressed and the stretched state. The outer tube is connected to the inner tube only in the first end of the inner and the outer tubes and in the second end of the inner and the outer tubes. The outer tube is moved in the transverse and longitudinal directions with respect to the inner tube at the transition of the tubes between the compressed and the stretched state. The hose comprises a connecting coupling for connection to a source of pressurized water at a first end and a water flow limiter at the second end of the hose.EFFECT: reduction of weight and dimensions of the hose during storage and transportation.24 cl, 8 dwg |
