A system for utilizing a pressurized fluid (33) includes first, second, and third coaxially disposed body members, each having a cylindrical shape. The third body member is movable relative to the second body member. The second body member has walls that define a cavity (30a) between the first and second body members and a passage within the second body member that directs pressurized fluid (33) from a cavity (30a) to the third body member. A method of utilizing a pressurized fluid (33) includes providing a coupling and a housing (16a) having a cavity (30a) defined therebetween, supplying pressurized fluid (33) to the cavity (30a), and providing a first passage (32a) that extends from the cavity (30a) to a first axially-facing surface of a non-rotating component (23a). The cross-sectional area defined perpendicular to a local flow direction is configured for choked flow within the first passage (32a). |
