Abstract:
The helix heated hoses 10 and 12 use two features to increase the flexibility. The first feature is a braided-copper heating element 14, which has increased flexibility over the prior art solid copper heating element. The element is spiral wound around the hose and held in place with a moisture barrier 16. The second feature is the helix twist 18 located just before the point where the hoses 10 and 12 attach to the manifold 20. The helix feature is created with the helix support 22, which initiates the twist around 24 inches back from the point of termination. The helix feature works to reduce the moment of inertia about the neutral axis 26 of the two supply hoses 10 and 12.
