Abstract
In a turbocharger for receiving exhaust gas from an internal combustion engine and for delivering compressed air to the internal combustion engine, a backplate may include a lubricant stall protrusion, such as a rib, may be placed in recirculation or collection recesses of the backplate to stall recirculating lubricant flow and direct the lubricant into a bearing housing lubricant core and drain to reduce an amount of lubricant proximate piston rings and leaking into a compressor housing of the turbocharger. When an lubricant deflector is used, the lubricant stall protrusion stalls recirculating lubricant that is outboard of the lubricant deflector, and may have an outer protrusion edge closely matching the outboard contour of the lubricant deflector to minimize a flow gap there between.
