A shaft sealing arrangement includes a first seal and a second seal, wherein the first seal is designed in the form of a lip seal and the second seal is designed in the form of a mechanical seal. When the shaft is at a standstill, the lip seal performs the sealing action and, when the shaft is rotating, the mechanical seal performs the sealing action.

The invention relates to a shaft seal (1) which is configured to seal a shaft (2) between a coolant side (8) and a dry side (9) in a water pump. The shaft seal (1) is particularly characterized in that a compressible volume compensator (7) for compensating a temperature-dependent volume fluctuation is provided, which is vertically disposed and interacting with the volume of a barrier fluid (6).

The invention relates to a seal system (100, 200, 300) for an installation (400) for producing a three-dimensional workpiece by means of an additive layer manufacturing method, the seal system (100, 200, 300) comprising: a first seal (102), which is configured to seal an intermediate space (116) at a first periphery (108) between a process chamber inner wall (110) and a powder-material-supporting plate assembly (112) in a process chamber (410) of the installation (400); and a second seal (104), which is configured to seal the intermediate space (116) at a second periphery (114) between the process chamber inner wall (110) and the powder-material-supporting plate assembly (112) in the process chamber (410) of the installation (400), the first seal (102) being spaced apart from the second seal (104) such that, when the intermediate space (116) is sealed between the process chamber inner wall (110) and the plate assembly (112) by means of the first seal (102) and the second seal (104), a channel (106) is formed between the first seal (102) and the second seal (104) at an edge of the seal system (110).

A tribometer includes a main chamber to conduct testing under controlled environmental conditions, such as different chamber pressures and different temperatures. A shaft extends through the main chamber to initiate component movement inside the main chamber. A secondary fluid seal chamber is formed in a wall of the main chamber around each shaft. A first seal is formed around the shaft on a first side of the secondary chamber. A second seal is formed around the shaft on a second side of the secondary chamber.

A shaft seal assembly is configured for sealing, for example, a reciprocating axial-movement shaft. The shaft seal assembly includes an annular elastomeric seal body having at least one first sealing surface configured to sealing engage a shaft. A lubricant reservoir body includes a second sealing surface and comprises a polymer matrix having a porous structure containing micro-pores, wherein the micro-pores are filled with lubricating oil.

A sealing device for sealing off the intermediate space between a housing and a shaft which is mounted rotatably in the housing, which housing has a first plate-like body with a front side, a rear side and a first opening extending from the front side to the rear side and suitable for the leadthrough of the shaft, and has a line which runs in the body and which is suitable for conducting a liquid or gaseous medium. Here, the first body is suitable for being fastened sealingly to the housing such that the shaft which is rotatably mounted in the housing is led through the first opening. The line has a multiplicity of outlets which are connected to an inlet via at least one diversion and/or at least one divergence and which lead radially symmetrically into the first opening. The first opening is suitable for the introduction of first sealing such that the first sealing seals off an intermediate space between the shaft and the first body without blocking the outlets of the line.
