  We probe the role that the directional asymmetry, between relativistic
outflows and kilo-parsec scale jets, play in the acceleration of cosmic rays.
For this reason we use two powerful, nearby Active Galactic Nuclei (AGNs).
These radio galaxies are atypical compared to the usual AGN as they contain
ring-like features instead of hotspots. Our VLBI radio data have revealed a
substantial misalignment between their small and large scale jets. Taking into
account the overall information we have obtained about the AGNs themselves (VLA
and VLBI radio data at 18 cm) and their clusters (X-ray observations) our study
supports the present ideas of powerful radiogalaxies (radio quiet and radio
loud) being sources of cosmic rays as well as their ability to accelarate the
latter to ultra high energies.
