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.

摘要： A tube- or hose connector for the transport of a fluid has at least at one end a ring type nipple 2 with a cross hole 4, which serves to mount the connector at an aggregate for receiving a banjo bolt 12 having a head 13 and a threaded shank 14 as well as two gaskets 10, 11. It has a protecting cap 18 to hold together a premounted unit of ring type nipple 2, banjo bolt 12, and the two gaskets 10 and 11, and has an approximately U-shaped form with a clamp 19, at the one end of which a flank 20 overlaps the head 13 of the banjo bolt 12 and at the other end of which a protecting cover 20 for the threaded shank 15 of the banjo bolt 12 is provided. The protecting cap 18 has an extension 26 supporting itself at the threaded shank 15 of the banjo bolt 12, and the protecting cover 22 is borne pivotably at the clamp 19.
