Braided hose and method of making same

#1. Field of the Invention

#The present application relates to a hose for conveying fluid and, more particularly, to a braided hose that is configured to reduce or prevent rubber from protruding through gaps in the outer braid.

#2. Description of the Related Art

#It will be appreciated that the illustrated boundaries of elements in the figures represent one example of the boundaries. One of ordinary skill in the art will appreciate that one element may be designed as multiple elements or that multiple elements may be designed as one element. An element shown as an internal component of another element may be implemented as an external component and vice versa.

#Further, in the accompanying drawings and description that follow, like parts are indicated throughout the drawings and description with the same reference numerals, respectively. The figures may not be drawn to scale and the proportions of certain parts have been exaggerated for convenience of illustration.

#FIG. 1 illustrates a perspective view, partly cut away, of one embodiment of a hose 100.

#Certain terminology will be used in the foregoing description for convenience in reference only and will not be limiting. For example, the terms “forward,” “rearward,” “right,” “left,” “upper,” and “lower” designate directions in the drawings to which reference is made, with the terms “inward,” “interior,” or “inner” and “outward,” “exterior,” or “outer” referring, respectively, to directions toward and away from the center of the referenced element, and the terms “radial” and “axial” referring, respectively, to directions perpendicular and parallel to the central longitudinal axis of the referenced element.

#Illustrated in FIG. 1 is a perspective view, partly cut away, of one embodiment of a hose 100 for conveying a fluid, such as air, hydraulic oil, lubricating oil or fuel. As shown in FIG. 1, the hose 100 is a multi-layer structure that includes a rubber layer 110, a reinforcing layer 120 surrounding the rubber layer 110, a barrier layer 130 surrounding the reinforcing layer 120, and an outer cover 140 surrounding the barrier layer 130. Each of these layers will be discussed in more detail below.

#In basic dimensions, the hose 100 extends axially to a predetermined length along a central longitudinal axis A, and has an inner diameter Di and outer diameter Do. The dimensions of the inner diameter Di and the outer diameter Do can vary depending upon the particular fluid conveying application involved.
