Abstract

A return flow filtration assembly for filtering return hydraulic fluid is provided. The filtration assembly includes a first return fluid chamber including a first inlet and first and second of outlets. The second outlet is configured to be coupled to a secondary return flow filter for providing micro-filtering of the return fluid. The first outlet includes a restriction element for restricting flow through the first outlet and generating an artificial back pressure within the first return fluid chamber to drive fluid through the second outlet, when the second outlet is coupled to a secondary return flow filter.
