Claim 0:
1. A turbocharger comprising:
a bearing device which is arranged between a compressor and a turbine and which is designed to support a shaft, said bearing device having a bearing housing in which an oil-lubricated bearing for supporting the shaft is arranged,
wherein the shaft has a slinger element extending in a circumferential direction for centrifugally dispersing a lubricating oil,
wherein the bearing housing has an oil drainage channel for discharging the lubricating oil from the bearing housing,
wherein an inner region of the bearing housing forms an oil delimitation chamber which is sealed off by seals arranged between the shaft and the bearing housing,
wherein the oil delimitation chamber has a deflection means, wherein the deflection means is shaped to deflect the lubricating oil that is centrifugally dispersed by the slinger element and shaped to conduct deflected lubricating oil in an opposite direction to the seals,
wherein the oil delimitation chamber is formed near the slinger element such that the lubricating oil centrifugally dispersed by the slinger element during operation of the turbocharger can be transferred straight from said slinger element to the deflection means, and
wherein the slinger element is formed such that the lubricating oil sprayed away from the slinger element has a radial directional component and an axial directional component, wherein the axial directional component runs in the opposite direction to the seals, and
wherein the bearing device further comprises a bearing flange, the bearing flange and the bearing housing defining the oil delimitation chamber, a wall element extending from the bearing flange, the wall element positioned separately from the slinger element and configured to prevent the lubricating oil from flowing back into a spray channel.
