Leakage sealed camshaft adjuster with return spring

摘要

The adjuster has a rotor (5) including a core and blade (7). The rotor includes an elevation profile sliding along its diameter with minimum radius. The largest profile is provided in extremities (73) of the blade such that a spring chamber (53) extends along a rotor surface, where the chamber completely lies in an area of the core. The width of the chamber is larger than the height of the chamber. The chamber is surrounded by a rotor core edge (29) in a radial direction of the blade, where the chamber has a space rinsed with hydraulic medium such as oil.
