Abstract:
In a flexible hose construction comprising an inner corrugated hose made of polymeric material and having a plurality of outwardly convex projections with recesses therebetween and extending from one end thereof to the other end thereof, and an outer sleeve of reinforcing material disposed in telescoping relation on said inner hose, the improvement comprising a tube of polymeric material disposed between said inner hose and said sleeve of reinforcing material so as to extend in a generally straight-line manner from projection to projection of said inner hose so as to tend to prevent said sleeve of reinforcing material from entering into said recesses of said inner hose an amount that would tend to substantially reduce the flexibility characteristics of said inner hose, said inner hose having an inside diameter of approximately 1.5 inch, with the distance between the apexes of said projections being approximately 0.246 of an inch, the thickness of the inner portions of said hose being approximately 0.045 of an inch, and the side walls of said projections disposed at an angle of approximately 10 degrees to a true transverse line passing through said inner hose.
