Zusammenfassung:	A rocker arm assembly includes first and second rocker arms defining a pivot location. The first rocker arm includes, toward a first axial end thereof adjacent the pivot location, a fulcrum surface and, toward a second axial end thereof, a latch assembly including a latch member moveable between latched and unlatched conditions relative to a latch surface defined by an adjacent portion of the second rocker arm. The latch assembly further including a spring biasing the latch member toward one of the latched and unlatched conditions, and a pressure chamber operable to bias the latch member toward the other of the latched and unlatched conditions. The first rocker arm further includes a fluid passage having a first end in open fluid communication with the fulcrum surface and a second end in open fluid communication with the pressure chamber of the latch assembly.
