摘要： A protective device for a stern tube seal of a propeller-driven vessel, wherein an intermediate space is left open between a stern tube and a propeller hub, which intermediate space is covered by a tubular protective cover concentric with the propeller hub, which protective cover is fixedly anchored to the stern tube and axially overlies the propeller hub leaving an annular gap, wherein a ring concentric with the propeller hub and U-shaped in radial section is disposed inside the protective cover in the intermediate space between the stern tube and the propeller hub, the U-opening of which ring is directed radially outward, and wherein the ring is at least partially formed of a material that has a pourable consistency at 20° C.

摘要： A seal apparatus, for sealing around a rotating shaft such as a propeller shaft of a watercraft between the exterior water and an interior lubricant space, includes a multiple seal arrangement with plural seal rings forming seal chambers therebetween, and plural fluid medium lines supplying and/or returning a respective fluid medium to a respective seal chamber. A section of a first medium line is formed as an axial passage through a housing of the apparatus, and a section of a second medium line is formed by a pipe arranged within the axial passage in the housing. A method of making such an apparatus especially by retrofitting an existing seal arrangement involves inserting a pipe into an axial passage in the housing in order to establish two medium lines through the housing where there was previously only one medium line.
