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 of 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.

Flexible cord-like hollow object

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.

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.

Hollow body in the form of a flexible bar

A device for damping the sound emission from oscillatory components of a fluid container of a hydraulic system, primarily in a motor vehicle. At least one vibration damping mass is coupled to the wall of a component subject to sound damping. The mass is adapted to the vibration to be damped by selection of material, shape, and/or position on the wall. For example, the mass is a rib fastened to the wall or a strip adhered to the wall. In an alternate embodiment, the container has an inner and an outer wall with a gap between them. The gap is either evacuated, filled with a sound absorbing material or ribs on the wall extend in the gap or inside the inner wall.

Sound damping device for oscillatory components of a motor vehicle

To damp the sound in an air conditioning system, particularly a vehicle air conditioning system, a tubular sound damping body is provided having openings at its opposite ends through which a liquid or gaseous medium flows. A respective connection tube is fitted at at least one and preferably at both of the openings, with the tube being of smaller cross-section than the sound damping body and the openings into the sound damping body. An isolating device in the form of an isolating element is around the inserted portion of each connection tube and also engages the interior of the sound damping body. Isolating element receiving recesses may be defined in the inserted end portion of the connection tube and the ends of the sound damping body for receiving the isolating elements. The isolating elements are comprised of an elastic rubber like material. Alternately, a spacer may be disposed around the elastic isolation device and engages the isolation device on the inside and the sound damping body on the outside.

Sound damping means for air conditioning system

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.
