Abstract: An exhaust gas turbocharger may include a shaft mounted in a bearing housing carrying a compressor wheel and a turbine wheel. The shaft may include a sealing bush arranged on the shaft in a rotationally fixed manner. The sealing bush together with a bearing housing cover may at least partially delimit an annular oil centrifuging space arranged coaxially to the sealing bush. The bearing housing cover may include a guiding nib located radially outside the sealing bush partially covering the sealing bush in axial direction. The guiding nib may be configured to guide oil separated in the oil centrifuging space onto the rotating sealing bush. The rotating sealing bush may be configured to direct the oil into the oil centrifuging space in response to centrifugal force creating an oil swirl.

Abstract: The invention relates to a charging device (1), more preferably an exhaust gas turbocharger for a motor vehicle, with a turbine housing (3) adjoining a bearing housing (2), in which a variable turbine geometry (4) is arranged. It is substantial for the invention that a one-piece disc spring (5) of plate with a bent over edge region is provided, wherein the bent over edge region forms a spring leg (6), while a protective leg (7) is designed as heat protection for the spring leg (6), that the spring leg (6) on the one hand supports itself on the bearing housing (2) and on the other hand on the variable turbine geometry (4), preloading the latter against the turbine housing (3).
