A line captain reported his concerns as he continues to be assigned B737-800 aircraft with known cfm-56 thrust reverser malfunctions. Repetitive cycling of engine thrust reversers to clear engine accessory unit (eau) faults and reverser overhead light illuminations have not corrected the system warnings.

Narrative:
I continue to be assigned B737-800 aircraft with known; hidden thrust reverser malfunctions. Direct and indirect pressure from certain management individuals continues to some degree or another. I have previously reported in great detail the exact malfunction as I had in this aircraft today; this particular flight. [During] this sequence [of flights] I [recently] finished; I had three separate aircraft with this malfunction. I have had this same problem in recent months; same request for positive corrective action; same inappropriate sign-off by clearing the engine accessory unit (eau) [faults] and cycling the thrust reverser. Maintenance attempted to sign-off as I just mentioned; but I said I would refuse aircraft unless reverser was pinned [locked-out]. The current list of aircraft with this malfunction I have personally found includes six tail numbers. None to date have been fixed. Every time I fly these planes. Every time; the same thrust reverser (T/right) issue is always there.
