Abstract

Improvements relating to pressure hoses with internal reinforcing elements, and with an inner core and an outer jacket of rubber or rubber-like plastic, said internal reinforcing elements consisting of parallel layers of wires that preferably pass in pairs in pairs. opposite direction around the inner core, the threads of the inner reinforcing elements always forming an angle with the longitudinal axis of the hose, characterized in that the angles of all the layers of thread coincide with the longitudinal axis of the hose and that the yarns of different yarn layers or pairs of yarn layers possess from the inside out a total cross section that grows according to the surface cross section of the individual tube calculation, the diameters and/or the number of the yarns being formed the different layers or pairs of layers variably against each other.
