Abstract:
1. A corrugated hose pipe assembly comprising: a corrugated pipe having first and second ends; an elastomeric high-pressure hose surrounding said corrugated pipe and having first and second end regions defining respective end faces; first and second pipe pieces having respective first ends fixedly connected pressure tight to corresponding ones of said first and second ends of said corrugated pipe; said first and second pipe pieces having respective peripheral, radially projecting fixed nipple stops at said first ends; said first and second pipe pieces having respective free second ends; first and second hose nipples supported form tightly on corresponding ones of said pipe pieces; each one of said hose nipples being pushed from the free second end of one of said pipe pieces up to the nipple stop thereof thereby axially positioning the hose nipple; each one of said hose nipples having an end facing toward the free second end of the pipe piece on which it is mounted; each one of said hose nipples having a peripheral, radially projecting hose stop at said end thereof; said hose stop having a diameter corresponding approximately to the diameter of said elastomeric high-pressure hose and being in contact engagement with a corresponding one of said end faces of said elastomeric high-pressure hose; said first and second hose nipples extending into said elastomeric high-pressure hose at corresponding ones of said first and second end regions thereof; first and second crimp sleeves encompassing corresponding ones of said first and second end regions of said elastomeric high-pressure hose; and, said first and second crimp sleeves being concentrically pressed so as to fix said first and second end regions of said elastomeric high-pressure hose onto corresponding ones of said first and second hose nipples.
