FORMED HOSE WITH DIFFERENT FIBER-REINFORCED REGIONS

摘要

Formed hose configurations are provided which include an innermost elastomer layer, a first fiber-reinforcement region, and multiple second fiber-reinforcement regions. The first fiber-reinforcement region has a first fiber-reinforcement density, and is disposed, at least in part, at a bend region of the formed hose, and the multiple second fiber-reinforcement regions have a second fiber-reinforcement density, and are disposed at least at the first and second end regions of the formed hose. The second fiber-reinforcement density is greater than the first fiber-reinforcement density, and results in the first and second ends of the formed hose being less radially-deformable than the bend region of the hose. This facilitates providing a mechanical fluid-tight connection with a hose barb fitting when the formed hose is slid over the hose barb fitting, absent any clamp over the formed hose and hose barb fitting connection.

主权项

1. An apparatus comprising:
a formed hose sized to engageably slide over a hose barb fitting and form a mechanical, fluid-tight connection therewith, the formed hose being a permanently-shaped, partially-deformable, reinforced hose, formed with at least one bend intermediate a first end region and a second end region thereof, and comprising:
an innermost elastomer layer;a first fiber-reinforcement region of a first fiber-reinforcement density over the innermost elastomer layer and disposed, at least in part, at the at least one bend of the formed hose;multiple second fiber-reinforcement regions of a second fiber-reinforcement density over, at least in part, the innermost elastomer layer, with second fiber-reinforcement regions of the multiple second fiber-reinforcement regions being disposed at least at the first end region and the second end region of the formed hose, wherein the second fiber-reinforcement density is greater than the first fiber-reinforcement density; andwherein the first and second end regions of the formed hose are less radially-deformable than the at least one bend thereof due, at least in part, to the second fiber-reinforcement density of the second fiber-reinforcement regions at the first and second end regions of the formed hose being greater than the first fiber-reinforcement density of the first fiber-reinforcement region at the at least one bend thereof, the second fiber-reinforcement density facilitating providing the mechanical, fluid-tight connection when one of the first end region or the second end region of the formed hose is slid over the hose fitting, absent any clamp over the formed hose and hose barb fitting connection.
