| Zusammenfassung: | A rotating union comprises a housing, a bushing, a fluid conduit, an annular seal and a cap secured to the housing and having a fluid inlet. The bushing is received within a cylindrical recess in the housing, and the fluid conduit is rotatably received by the bushing and passes through the bushing and a bore in the housing. The annular seal is received within the housing recess, and sealingly engages a cylindrical outer surface of the fluid conduit and the cylindrical wall of the housing recess. The cap has a circular recess and surrounding annular projection which receives the input end of the fluid conduit. The annular seal is sandwiched between the bushing and the annular projection. When the fluid conduit rotates, its outer surface rotates under friction against the annular seal to maintain the seal. |
