Claim 21:
22. A setting tool for actuating a plug in a subterranean wellbore, comprising:
a generally cylindrical housing having an uphole end, a longitudinally opposed downhole end, and a throughbore extending between the uphole end and the downhole end;
a piston positioned at least partially within the throughbore of the housing and configured to move axially within the throughbore, wherein the piston defines an internal firing chamber within the piston that is in fluid communication with at least one exhaust port also formed in the piston;
an expansion chamber formed within the throughbore of the housing and positioned between an outer surface of the piston and an inner surface of the housing wherein the exhaust port is configured to convey combustion products along a combustion flowpath extending from the firing chamber and into the expansion chamber; and
an exhaust diffuser distinct from the piston and the housing and disposed in at least one of the firing chamber and the expansion chamber, wherein the exhaust diffuser comprises at least one baffle face oriented at an angle that is between 60° and 120° relative to a longitudinal axis of the exhaust port, the baffle face configured to redirect the flow of combustion products along the combustion flowpath, and wherein the exhaust diffuser further comprises an exhaust passage that extends from the baffle face to a downhole end of the exhaust diffuser.
