They are the “Control Valves” in your second figure, otherwise known as “Load Limiters”. I believe that they are not called RPR/RPL in post-RSEP aircraft because the activation criteria are different (135kts not RA/N1/Hyd pressure).
Your first figure is an amalgam of systems; it is meant to be read in the context of the text with it.
Anyway, enough from me. I look forward to other responses if I have mis-understood the rudder system in all its many forms!
