VARIABLE BLEED VALVE SYSTEMS INCLUDING A STOP MECHANISM WITH A SELF-LUBRICATING FOLLOWER NUT ASSEMBLY

摘要

Variable bleed valve systems thereof including a stop mechanism with a self-lubricating follower nut assembly are provided. Self-lubricating follower nut assembly includes a follower nut and a pair of grease reservoirs. Follower nut has a recess at each of a first end and a second end and a groove extending between the first and second ends. A grease reservoir is disposed within each recess. Each grease reservoir has an outlet opening substantially aligned with a corresponding end of the groove. Each grease reservoir is compressible to expel lubricating grease into the groove upon compression. The self-lubricating follower nut assembly is configured to translate along a hollow screw between opposed end stops disposed within a housing of the stop mechanism. Each grease reservoir is compressed each time the self-lubricating follower nut assembly impacts an end stop of the opposed end stops.
