Abstract

Die vorliegende Erfindung betrifft eine Ladeeinrichtung (1) für eine Brennkraftmaschine, insbesondere Abgasturbolader, vorzugsweise in einem Kraftfahrzeug, umfassend einen Rotor (2), der ein Verdichterrad (4) und eine Welle (5) aufweist, einen Stator (3), der ein Lagergehäuse (6) aufweist, in dem die Welle (5) um eine Rotationsachse (7) drehbar gelagert ist, und eine verdichterseitige Dichtzone (8), in der sich eine rotorseitige Dichtfläche (9) und eine statorseitige Dichtfläche (10) axial gegenüberliegen.The present invention relates to a charging device (1) for an internal combustion engine, in particular an exhaust gas turbocharger, preferably in a motor vehicle, comprising a rotor (2) 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 a rotation axis (7), and a compressor-side sealing zone (8) in which a rotor-side sealing surface (9) and a stator-side sealing surface (10) are axially opposite.

Eine verbesserte Dichtungswirkung lässt sich erzielen, wenn zumindest eine der Dichtflächen (9, 10) mehrere, in Umfangsrichtung verteilt angeordnete Vertiefungen (15) aufweist.

Figure imgaf001
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 the circumferential direction.
