In order to provide a seal arrangement for sealing between a first medium space filled with a first medium and a second medium space filled with a second medium which ensures reliable sealing between the medium spaces with very low leakage values even over a prolonged period of use, wherein said seal arrangement comprises a moveable component which is displaceable in the longitudinal direction thereof and/or rotatable about the longitudinal direction thereof and extends through the seal arrangement and wherein the seal arrangement comprises a sealing element which comprises a first sealing region that is sealing in relation to the first medium space and a second sealing region that is sealing in relation to the second medium space, wherein the first sealing region comprises a first dynamic sealing section abutting against the moveable component and the second sealing region comprises a second dynamic sealing section abutting against the moveable component and at least one of the two dynamic sealing sections has at least two sealing lips, it is proposed that each of the two sealing regions should comprise at least one respective spring element which biases the dynamic sealing section of the respective sealing region against the moveable component.

A radial shaft seal is provided for sealing between high and low pressure sides in an annular space between a shaft and a static structural receiving part, wherein the shaft seal is rotationally symmetric and arranged coaxially to the shaft. A first sealing ring has an inner periphery bulging toward the low pressure side and forms a first sealing lip abutting the shaft. A spacer ring has first and second faces directed towards the high and low pressure sides, respectively. An elastic shaped part has an outer periphery abutting the second face of the spacer ring and an inner periphery bulging toward the high pressure side and abutting the first sealing lip. At least the spacer ring and elastic shaped part define a cavity subjected to the high pressure side or a control pressure which presses the first sealing lip against the shaft via the elastic shaped part.
摘要:
To provide a tube comprising a wall, which comprises a fluoropolymer, in particular polytetrafluoroethylene (PTFE), a perfluoroalkoxy polymer (PFA) and/or a fluorinated ethylene propylene (FEP), and a colour marking and/or an X ray contrast marking, which may be identified and/or positioned through the colour marking and/or the X ray contrast marking without relinquishing the advantages of a tube made of fluoropolymer material, it is proposed that the colour marking or the X ray contrast marking comprises at least one marking element, which is produced separately from the wall of the tube and thermally welded to the wall.
