    • The present invention relates to a charging device (1) for a combustion engine, more preferably exhaust gas turbocharger, preferentially in a motor vehicle, comprising a rotor having a compressor wheel (4) and a shaft (5), a stator (3) having a bearing housing (6) in which the shaft (5) is rotatably mounted about an axis of rotation (7) and a compressor-sided sealing zone (8), in which a rotor-sided sealing surface (9) and a stator-sided sealing surface (10) are located axially opposite each other.An improved sealing effect can be achieved if at least one of the sealing surfaces (9, 10) has a plurality of depressions (15) arranged distributed in circumferential direction.
    • 本发明涉及一种用于内燃机的充气装置(1),更优选的是排气涡轮增压器,优选地在机动车辆中,包括具有压缩机叶轮(4)和轴(5)的转子,定子(3) 具有轴(5)围绕旋转轴线(7)可旋转地安装的轴承壳体(6)和压缩机侧密封区域(8),转子侧密封面(9)和定子 - 密封表面(10)彼此轴向地相对定位。 如果密封面(9,10)中的至少一个具有沿圆周方向分布的多个凹部(15),则可以实现改善的密封效果。
