What do these abbreviations stand for?

I found the diagram for my vacumm system on AutoZone, but do not know what some of the abbrev(s) stand for. Could someone tell me what these are: VRDV, TAB, TAD, SV-CBV, CPRV. If I con be told what they are, maybe I can find them and continue checking the vacumm lines out for leaks, crackage and other problems. Thank you.

VRDV - Vacuum Retard Delay Valve
TAB - Thermactor air bypass
TAD - Thermactor air diverter
SV-CBV - Solenoid Valve Carb. Bowl Vent
CPRV - Canister purge regulator valve

Hope this helps

Yes, helps a lot. Thank you so very much. Off to autoparts store again now that I know what to ask for. I found all of them and today replace all the vacuum lines and EGR and a few other things that I know what they were. Also replaced the two fuel filters.
Slowly learning what to do and how, thanks to help from nice people like you.
