ABSTRACT:
A device for effecting mechanical prestressing in a pair of substantially concentric cylinders, in which the inner cylinder is prestressed in compression and the outer cylinder is prestressed in tension by means of the device in the form of a hose or hoses disposed in a gap between the cylinders and being subjected internally to a pressure medium, the hose or hoses being arranged helically in such a manner that the sum of the moments of the forces thereby caused by the pressure forces between the cylinders and occurring about the central axis of the cylinders in a plane containing such axis, is substantially zero.
