Abstract: An efficient flexible hose construction is provided which incorporates resistance, when subjected to high negative pressure loads, to the collapse failure known “rollover” or “shingling”. The construction relates to a means of increasing the torsion capability of a flexible hose where the hose is formed from a helical wire that is coated and thereafter is connected to and supports a shroud or cover. Improved resistance to rollover lies in mechanical enhancements to the interface between the helical wire and the coating material, where the enhancement assists in maintaining the wire and coating as an integral unit and prevents separation leading to shingling under high vacuum pressures. The mechanical enhancement requires use of a specialized cross-section for the helical reinforcing wire.
