SLANGSTYCKE AV ELASTISK PLAST MED GOD AATERHAEMTNING FOER OMSLUTNING AV ETT LINDNINGSPARTI HOS SKRUVTRYCKFJAEDRAR MED PROGRESSIV FJAEDERKARAKTAERISTISK

摘要

A length of hose made out of an elastic material that readily recovers its shape, especially intended for covering the coiled section of a helical compression spring with a progressive characteristic of the type employed in motor vehicles and similar machines. At least one terminating section of the length of hose has a shorter inside diameter and communicates with the remaining, cylindrical, section of the length of hose through an intermediate section that tapers conically at least inside.
