Engine 9111 · Vane cell adjuster

Engine 9111 Vane cell adjuster The vane cell adjuster mainly consists of the stator (red, above the chain sprocket, crankshaft-fixed), the rotor (green, camshaft-fixed) and the inserted vanes (yellow, inserted in rotor) and two covers. The stator is fitted with the chain sprocket on the outer diameter. It interlocks with the crankshaft via the chain drive. The rotor is securely bolted to the camshaft. Repositioning between rotor and stator is possible (inner bearing of adjuster). This repositioning is limited by the vanes inserted into the rotor and by the stops on the stator. The vanes also split the recesses on the stator into two chambers each. These chambers can be filled with oil via oil holes and oil guides in the rotor. To ensure efficient sealing, small springs are fitted between vanes and rotor. The chambers are each sealed laterally by a chain sprocket fixed cover. The adjuster is locked at a stop (retard stop). For this a spring-loaded pin in the retard 1_01_02 stop of the adjuster moves into a hole in the cover. This creates a interlocking connection between the stator and rotor during the engine starting process. Noise during this oil-pressure-free period is avoided by this locking process. 1_02_02 1 - 8 Service Information 2002
