摘要

The device (1) has a rotor (2) provided with a compressor wheel (4) and a shaft (5), and a stator (3) provided with a bearing housing (6) in which the shaft is rotatably supported around a rotation axis (7). A rotor-sided sealing surface (9) and a stator-sided sealing surface (10) are axially faced with each other in a compressor-sided sealing zone (8). The sealing surfaces exhibit recesses that are arranged in a distributed manner in a circumferential direction. The rotor-sided sealing surface is provided at a seal socket (11) attached at the shaft.
