Device for camshaft adjustment in internal combustion (IC) engine, has labyrinth seals for suppressing oil leakage between device components, including inner and outer rotors, side panels, and extension elements

摘要

The device (1) has inner and outer rotors (3,4) arranged between the side panels, and extension elements (8) radiated from the inner rotor to the outer rotor. Labyrinth seals (11), formed within both rotors, the side panels, and around the extension elements, suppress oil leakage between both rotors, extension elements, and the side panels. Each seal forms alternating ridges and valleys.
