POWER STEERING HOSE DESIGN FOR PERFORMANCE IN HIGH PRESSURE AND LOW TO HIGH VOLUMETRIC EXPANSION ENVIRONMENTS

摘要

A new and improved power steering hose assembly is described, which may c omprise a core hose layer, a first reinforcing layer, an intermediate hose l ayer, a second reinforcing layer and an outer hose layer. The first reinforc ing layer has a braid pattern formed in a 1-over, 1-under pattern. The inter mediate hose layer is positioned over the first reinforcing layer. The secon d reinforcing layer is disposed over the first reinforcing layer. The second reinforcing layer has a braid pattern formed in one of a 3-over, 3-under pa ttern or a 2-over, 2-under braid pattern. The outer hose layer is positioned over the second reinforcing layer.
