Abstract
A flexible, very high pressure hose as a flexible conducting member in hydraulic systems. The wall of the hose contains filamentary load-carrying cords which are embedded in two or more layers. The load-carrying cords are combined to form a plurality of strips which cross one another or are braided with one another. The present invention deviates from the heretofore known symmetrical arrangement where the strips of a given layer have the same number of load-carrying cords in both directions, and instead provides an asymmetrical layer construction including strips which in one direction have a different number of load-carrying cords than do the strips which extend in the opposite direction. While the local resistance to pressure remains the same, the advantages of the present invention are distinct improvements, primarily in the flexibility and the service life of the novel hoses.
