Abstract:
A tubular hose construction comprising:an first reinforcement layer formed of a first fiber material; an inner jacket surrounding the first reinforcement layer; a second reinforcement layer surrounding the inner jacket and formed of a second fiber material; an outer jacket covering the second reinforcement layer; a first elastomeric layer having a first inner radial surface, and a first outer radial surface; a helical reinforcement element spiral wound over the first elastomeric layer at a predetermined pitch angle measured relative to the longitudinal axis; and a tubular second elastomeric layer surrounding the helical reinforcement element and surrounded by the first reinforcement layer, the second elastomeric layer having a second inner radial surface and a second outer radial surface, the helical reinforcement element being encapsulated between the first outer radial surface of the first elastomeric layer and the second inner radial surface of the second elastomeric layer.
