Abstract
A hydraulic fluid reservoir for a hydraulic power system includes a reservoir housing having an internal chamber for containing a supply of hydraulic fluid, an outlet for communicating the fluid from the housing to an inlet of a hydraulic pump, and a return flow inlet for receiving a return flow of fluid into the chamber. The reservoir includes a flow diffuser having a diffuser inlet communicating with the return flow inlet for receiving at least a fraction of the return flow into the diffuser. The diffuser has an inner fluid guide wall that is preferably conical which diverges in the downstream direction in order to quiet any turbulence in the flow within the diffuser and to discharge into the bulk of the fluid into the chamber to be deaerated.
