HOSE FOR PASSING FLUID MEDIUM AND METHOD OF ITS MANUFACTURE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; fluid media handling. SUBSTANCE: invention relates to hose designed for passing fluid medium under pressure and method of its manufacture. Wall of hose contains at least one wall part 5. said wall part 5 is connected with at least one extensible part 4 to form solid sheathing of hose so that circumference of hose changes between minimum size when extensible part 4 is not extended and maximum size when extensible part 4 is extended to maximum value. Extensible part 4 passes in cross and longitudinal direction of hose, and wall parts 5 are made for displacement relative to each other, both in cross and longitudinal direction of hose at increasing of circumference and extending of extensible part 4. wall and extensible parts are formed differently on different sections 1, 2, 3 along the hose to provide control of direction of movement of different sections 1, 2, 3 at extending or vibrating of hose. Invention relates to method of manufacture of such hose. According to proposed of manufacture, shape forming material is extruded together with hose material which is designed for use as preliminary form of hose material to get required configuration of extensible and wall parts. EFFECT: possibility of checking direction of movement of hose parts at building the pressure. 19 cl, 9 dwg
