Semi-disposable pre-conditioned air supply hose conduit and connectors for attaching end portions of the same

Abstract

A tubular fluid conduit (10) which is especially adapted for use in supplying preconditioned air to an aircraft being serviced, wherein the tubular conduit (10) may be fabricated as a thermoplastic extrusion having a constant diameter dimension, whereby a first end portion (12) may be fluidically connected to a large diameter supply conduit while a second end portion (20) may be fluidically connected to a small diameter use conduit as a result of spiral wrapping (26) the second end portion (20) around the use conduit. Alternatively, the tubular conduit may be fabricated as a thermoplastic extrusion having repetitive sections with each section comprising relatively large diameter and relatively small diameter portions.

Problems solved by technology

[0006] It is further understood, however, that while this assembly technique is very satisfactory from the point of view of initially assembling, forming or erecting tubular fluid conduits, this fastening means does not really address the need for effective Means that enable relatively easy and rapid use of tubular fluid lines, relatively easy and rapid loading of tubular fluid lines, or performance of tubular fluid lines that can be stored in a relatively compact format and space to provide the entire tubular fluid line This additional important question

Moreover, it should also be noted that such conventional, prior art tubular fluid conduits have a predetermined, constant diameter range, therefore, such tubular fluid conduits can only be used with predetermined constant diameter ranges Fluid Flow System Connections of Tubular Fluid Piping
