ABSTRACT:
A flexible hose construction and method of making the same are provided, the flexible hose construction comprising an inner tube made of polymeric material, an outer sleeve of reinforcing material disposed in telescoping relation on the inner tube from one end thereof to the other end thereof, rib structure disposed between the sleeve of reinforcing material and the inner tube, the rib structure being disposed on the inner tube so as to define alternating coil structure of rib structure and coil structure of non-rib structure serially along the longitudinal axis of the inner tube in a like repeating pattern thereof, the coil structure of non-rib structure comprise coil structure of void space, and an outer tube of polymeric material disposed between the rib structure and the sleeve of reinforcing material so as to extend in a generally straight-line manner from coil structure of the rib structure to coil structure of the rib structure so as to tend to prevent the sleeve of reinforcing material from entering into the coil structure of void space an amount that would tend to substantially reduce the flexibility characteristics of the hose construction.
