Abstract
Impurities of a lubricant in traditional camshaft adjusters can cause a problem, leading to impairment in the function and service life of the camshaft adjuster. In order to address this, flow channel areas are provided in the lubricant circuit, which include a dead chamber () where impurities can be deposited as a result of centrifugal force. Alternatively or additionally, a labyrinth is used to deposit impurities.
