Embodiment Construction
[0020]The invention will now be described with reference to the drawing figures. Example embodiments of the heated hose of the present invention provide heating wires braided or threaded together with a strengthening material around the inner liner. Essentially, rather than attaching wires to a hose, the present invention provides a heating mechanism that is an integral component of the outer layer of the hose. The integration of the glass fibers with the heating wires allows the glass fibers and heating wires to be added in a single manufacturing step to form a lightweight hose assembly adapted for carrying treated exhaust treatment fluid and other fluids that need to be heated. Furthermore, the wire is braided, not wound, which may provide increased hoop strength for high pressure applications.
[0021]The present invention provides an integral heated hose, having a braided layer, which includes heated element wires and glass fibers. The aforementioned braided layer is advantageous b...
