  • Patent number: 6109306
    Abstract: A kink-resistant hose construction adapted for conveying fluids under high pressure which is flexible intermediate a central longitudinal axis to a minimum bend radius. The construction includes a thermoplastic core having an inner surface defining the inner diameter of the hose and an outer surface, and an innermost reinforcement layer disposed radially circumferentially about the outer surface of the core. The innermost reinforcement layer is formed as a composite of at least one metallic wire element and at least one non-metallic fiber element. The metallic wire element is wound helically in one direction over the outer surface of the core at a predetermined pitch angle measured relative to the longitudinal axis to define a series of first turns. Each of these first tuns is spaced-apart from an adjacent first turn to define successive pairs of first turns each having an interstitial area therebetween.
