Abstract

The invention relates to a camshaft adjustment device for an internal combustion engine, having a chamber housing, an actuating rotor which is received in the chamber housing and which can be pivoted about an axis which is concentric with respect to the circumferential axis of the chamber housing, wherein the actuating rotor has a plurality of dividing flanks which rise up radially over a cylindrical base surface of the actuating rotor, and in each case divide pressure chambers which are formed in the chamber housing into a first chamber section and a second chamber section. Sealing strips are inserted into the actuating rotor. The sealing strips form a fluid passage path. The latter can be blocked via a check valve device in such a way that the fluid passage is possible only in one direction.
