Variable inlet guide vanes for a compressor.

摘要

Fluid flow guide vanes (12) in an axial flow compressor are rotatably mounted at one end (16) in the compressor frame (20) so that they can pivot between an open and a closed position. The other end of each vane has a button (34) engaging in and forming a clearance with the walls of a bushing portion (24) of the frame, the button being eccentrically offset (36) with respect to the rotational axis (18) of the vane by a preselected amount and in a preselected direction to cause the button to provide restraining force on that end of the vane when the vanes are in an open position.
