摘要:
A flexible cord-like hollow object for the transportation of media is provided with an inner zone enclosed by a casing. A barrier layer, which is impermeable to volatile molecules of the medium to be transported, is provided on the casing surface facing the inner zone. The barrier layer comprises sub-elements that are arranged in a scale-like manner.
摘要:
A hose for transporting preferably gaseous media at high temperatures and under high pressure has a corrugated interior surface with depressions and elevations, and at least one insertion element that can be inserted in one end. The hose is characterized in that, in the region of contact between the interior surface of the hose and the exterior surface of the insertion element, at least one gasket element of crystalline material is provided. The gasket element is metal, preferably a lead or copper alloy.

A flexible cord-like hollow object for the transportation of media is provided with an inner zone enclosed by a casing having an inner layer, a middle layer and an outer layer. A barrier layer, which is impermeable to volatile molecules in the medium to be transported, is integrated into the casing on the outer surface of the inner layer between the inner layer and the middle layer. The barrier layer comprises sub-elements that are arranged in a scale-like manner.
摘要:
An expandable hose that reduces the hammering produced in hydraulic systems by pumps. A tubular outer section of flexible material has a fitting at each end and loosely accommodates a tubular inner section of flexible material, leaving a hollow space between them. One end of the inner section communicates with one of the fittings, allowing fluid to flow through it, whereas the other end is free and open. A fluid-conveying channel is left between the free end of the inner section and the other fitting. There is a constriction between the inner section and the outer section that separates the tubular channel from the fluid-conveying channel. The wall of the inner section is solid in the vicinity of the tubular channel, so that fluid can enter the tubular channel from the fluid-conveying channel only by way of the constriction. The position of the constriction dictates the ratio of the capacity of the tubular channel to that of the fluid-conveying channel in terms of frequency.

A multi-positional collapsible seat assembly for a motor vehicle is disclosed. The seat assembly includes a seat bottom having a load surface provided on an underside thereof and a seat back having a load surface provided on the back side thereof. As the seat assembly is collapsed, the seat bottom is pivoted forward and the seat back is pivoted adjacent to the seat bottom such that the load surfaces collectively provide a load floor for receipt of cargo. An armrest assembly is disclosed that facilitates both passenger and cargo transport. A method is also disclosed for collapsing the seat assembly.
