Abstract: Oil sealing unit for a turbocharger used for sealing a passage from a bearing housing to a compressor housing. An end wall serves to delimit an oil expansion chamber in the direction of a compressor wheel. A sealing sleeve is designed for a non-rotating connection with a shaft, which connects the compressor wheel to a turbine wheel. The sealing sleeve is at least partially surrounded by the end wall. An oil guiding means is designed in such a way that an overhang is formed in relation to an oil deflection ring and in a direction radially upward in relation to at least a portion of the oil deflection ring. A sealing gap is formed between the overhang of the oil guiding means and the oil deflection ring.
