COMPACT VARIABLE PITCH FAN |
摘要 |
A compact variable pitch fan has a hydraulic pitch change mechanism. A pitch change piston is constrained to follow reciprocating motion under hydraulic control within a peripheral hub from which fan blades extend outward. An additional feature is the use of separated guiding and seal surfaces. A still further feature is the use of a pitch sensor, particularly on the hydraulic line leading to the variable pitch fan.
