We present the analysis of the latest Suzaku observation of 3C111 performed on three epochs spaced by 7days. We detected an anti-correlated variation of a relativistic line, consistent with reflection from an ionized disk at 10rg from the central black hole, and blueshifted FeK absorption lines, indicative of the ejection of an outflow with velocity 30,000km/s, following a flux increase. This may provide the first direct evidence of accretion disk-winds coupling in an AGN, similar to what observed in the microquasar GRS1915+105. We show also the results of our ongoing systematic spectral analysis of long Suzaku observations of broad-line radio galaxies. The main result for 3C382 is the detection of a relativistic iron line consistent with reflection from a highly ionized region of the disk at 10-20rg, viewed at an inclination of 30deg. This provides the most detailed profile for such lines in a radio-loud AGN to date. Moreover, we discovered the presence of blueshifted FeK absorption lines in three out of five sources, namely 3C111, 3C120 and 3C390.3, which are indicative of ultra-fast outflows with velocities 10,000-50,000km/s. A detailed photoionization modeling reveals a very high ionization, large column densities and a location on sub-pc scales, which indicates a likely association with accretion disk winds, similar to Seyferts and BAL-QSOs. The high associated mass outflow rate and the mechanical power comparable to that of jets then suggests they may play a new significant role in the AGN cosmological feedback.
