Abstract
A flexible hose construction and method of making the same are provided, the flexible hose construction comprising an inner corrugated hose made of polymeric material and having a plurality of outwardly facing convex projections with outwardly facing recesses therebetween and extending from one end thereof to the other end thereof, the inner hose having a plurality of inwardly facing convex projections with inwardly facing recesses therebetween and extending from the one end thereof to the other end thereof, an outer sleeve of reinforcing material disposed in telescoping relation on the inner hose, a first tube of polymeric material disposed between the sleeve of reinforcing material and the inner hose and having an inner peripheral surface engaging the outwardly facing convex projections in a generally straight-line manner from the one end thereof to the other end thereof so as to tend to prevent the sleeve of reinforcing material from entering into the outwardly facing recesses of the inner hose an amount that would tend to substantially reduce the flexibility characteristics of the inner hose, and a second tube of polymeric material disposed inside the inner hose and having an outer peripheral surface engaging the inwardly facing convex projections in a generally straight-line manner from the one end thereof to the other end thereof.
