Patent ID: 8752591

Claim:
A kink, crush and burst resistant hose having a longitudinal axis and a lumen for conveyance of a fluid comprising (1) an inner tubular layer, (2) a fabric reinforcing layer wherein said fabric reinforcing layer is comprised of a first plurality of reinforcing cords which extend spirally through the hose and are substantially parallel to each other and a second plurality of reinforcing cords which extend spirally through the hose and are substantially parallel to each other, wherein the first plurality of reinforcing cords are oriented at an angle α which is within the range of 20° to 50° of the longitudinal axis of the hose, and wherein the second plurality of reinforcing cords are oriented at an angle β which is within the range of 60° to 85° of the longitudinal axis of the hose, wherein the angle α and the angle β are mutually opposite with respect to the longitudinal axis of the hose (3) an outer tubular layer, and (4) at least one reinforcing strip which is at least partially embedded within the outer tubular layer and helically wound in the direction of β with respect to the orientation of the reinforcing cords and a pitch about the lumen of said hose, wherein said hose has a ratio of bend stiffness to torsional stiffness which is greater than 1.0.
