Abstract: An engine turbocharger (10) includes a radially oriented oil deflector (50) that incorporates an oil guiding feature (70) to improve control of a continuous turbulent mass of oil being impelled against the deflector by an oil flinger (35). The oil deflector (50) has a downwardly extending tongue (60) to assist in directing oil flow from a thrust bearing chamber. The feature (70), formed on the tongue (60), enhances otherwise gravitationally directed oil flow into an engine oil sump. The feature is vertically oriented, and redirects oil thrown axially and rotationally against the deflector, providing improved piston ring sealing through more efficient evacuation of oil from the thrust bearing chamber. The feature may be formed by stamping, as either an integral disruptive surface rib, or as an otherwise radially oriented flange protruding axially from the surface of the tongue. Such flange may be integral with, or otherwise attached to, the oil deflector tongue, as for example via welding.

Abstract: A low-backlash multimode clutch includes a one-way bearing allowing rotation in a first direction as well as a number of actuatable pawls in one race and a number of receiving slots having engagement faces in the other race. The engagement faces are tilted such that when the pawls are actuated, any torque applied in the first direction tends to force the pawls outward but the pawls are retained inward, such as by actuator rods. In this way, the one-way clutch may be selectively locked and unlocked with zero backlash against the one-way bearing.
