Abstract
In one exemplary embodiment of the invention, an assembly for an internal combustion engine includes a crankshaft, a drive mechanism coupled to the crankshaft and an oil pump actuated by the drive mechanism. The engine also includes a vacuum pump actuated by the drive mechanism, wherein the drive mechanism, oil pump and vacuum pump are disposed in an oil pan and a housing disposed between the oil pump and vacuum pump configured to enclose at least a portion the drive mechanism and restrict a flow of oil from the oil pan into the housing to reduce aeration of the oil during operation of the internal combustion engine.
