Title:
INLET GUIDE VANE ACTUATOR ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2021/085092
Kind Code:
A1
Abstract:
An inlet guide vane assembly for a centrifugal compressor includes a plurality of guide vanes, a drive structure coupled to the plurality of guide vanes, an actuator and an actuation mechanism. The rotation of the drive structure transitions the plurality of guide vanes from a first position to a second position. The actuation mechanism is configured to transition the plurality of guide vanes between the first and second positions based on operation of the actuator. The actuation mechanism imparts a first amount of rotational force to drive the drive structure when the guide vanes are in the first position and a second amount of rotational force when the guide vanes are in the second position. The actuation mechanism provides a mechanical advantage to the actuator when the guide vanes are in the first positions as compared to when the guide vanes are in the second position.
