An article that is configured to be rotatably mounted includes an embedded hollow cavity into which at least one dampening member is inserted. The dampening member or members frictionally engage the hollow cavity such that relative movement between the dampening member or members and the hollow cavity operates to attenuate vibration that is generated when the article is rotated.

An article that is configured to be rotatably mounted includes an embedded hollow cavity into which at least one dampening member is inserted. The dampening member or members frictionally engage the hollow cavity such that relative movement between the dampening member or members and the hollow cavity operates to attenuate vibration that is generated when the article is rotated. inlet and having an axis around which said vane is rotatable; an actuation member engaged with said vane near its trailing edge, said member being operable to selectively cause said vane to rotate about said pin axis; and a slot formed in each of said vanes for slideably receiving either said pivot pin or said actuation member so fast to accommodate relative radial movement between said vane and said actuation member wherein each of said actuation members are interconnected to a common ring which is selectively rotatable to move said plurality of vanes in substantial unison and further wherein said ring is rotatably mounted on an outer surface of an annular portion of a diffuser housing with no structure being immediately surrounding its radially outer edge. 12. A vaned diffuser as set forth in claim 11 wherein a said actuation member comprises a shaft and an associated eccentric cam surface which engages said vane, with the shaft being rotatable to cause said vane to rotate. 13. A vaned diffuser as set forth in claim 12 wherein said slot is near said vane trailing edge and said cam surface is disposed in said slot. 14. A vaned diffuser as set forth in claim 12 wherein said cam surface is round and is mounted in a round opening in said vane. 15. A vaned diffuser as set forth in claim 11 wherein said pivot pin is integral was said vane. 16. A vaned diffuser as set forth in claim 11 wherein said pivot pin is disposed in said slot. 17. A vaned diffuser as set forth in claim 11 wherein said actuation members are integral with said ring and are located in openings formed in said vanes. 18. A vaned diffuser as set forth in claim 17 wherein said vane openings are elongated to allow reciprocal movement between said actuation members and said vanes. 19. A vaned diffuser as set forth in claim 11 wherein the radially outer edge of said ring is substantially radially aligned with said vane trailing edges.
