Abstract
A flow restrictor assembly includes a threaded element and a sleeve. The threaded element defines a plurality of threads that extend from a first threaded element end towards a second threaded element end. The sleeve has an inner sleeve surface that engages edges of a portion of the plurality of threads and extends between a first sleeve end and a second sleeve end. A lubrication flow path is defined by the portion of the plurality of threads and the inner sleeve surface and is arranged to create a pressure drop in a lubricant that flows through the lubrication flow path.
