Definitions
- Known vane-cell camshaft adjusters have a rotor with a plurality of radially projecting vanes which are pressed radially outward against a stator housing by the force of a spring.
- a plurality of radially inwardly projecting stops are formed on the stator, which limit the adjustment movement of the rotor in both directions of rotation when the blades run against the stops.
- the wings rest with their end edges on the stator, so that between each wing side and the adjacent side of a stop of the stator, a chamber is formed, into which a fluid, usually the engine oil, is conveyed via a valve assigned to the camshaft adjuster.
- the stator serves on the one hand to separate and seal the fluid chambers, on the other hand to determine the adjustment angle between the camshaft and the crankshaft.
- a particularly favorable stress curve results if the transition between the non-enlarged and the enlarged groove cross section is curved. is shaped.
- the transition between the two cross sections with different diameters, which is designed as an arc, causes a gradual increase in stress, so that local stress peaks are avoided.
