Flexible hose for high pressures and temperatures including a charge-air hose and a cooling-water hose

摘要

A flexible hose (1) has at least two textile reinforcement inlays or inserts (5, 6, 7) and an inner layer (2) made of elastomeric material. The flexible hose can assume various curvature geometries and, on the other hand, is still pressure-resistant because a textile reinforcement inlay (5) made of a peripherally closed, tubular knitted or woven fabric is applied to the elastomeric inner layer (2). A textile layer (6), which is rubber-coated on both sides, is wound as a further textile reinforcement inlay onto the tubular knitted or woven fabric (5).

主权项

1. A charge-air hose or a cooling-water hose comprising:
an elastomeric inner layer; a first textile reinforcement layer applied to said elastomeric inner layer; said first textile reinforcement layer being made of a tubular knit or braid; a second textile reinforcement layer wound on said first textile reinforcement layer; said second textile reinforcement layer having an inner side facing toward said first textile reinforcement layer and an outer side facing away from said first textile reinforcement layer; said second textile reinforcement layer being bilaterally rubberized; said second textile reinforcement layer being selected from the group consisting of a flat knitted fabric, a flat woven fabric and a flexible flat woven material; said hose having a curvature and being vulcanized to completion after said second textile reinforcement layer has been wound on said first textile layer; said hose being flexible in an axial direction; and, said hose having expanded ends.
