An apparatus (10) for inflating an inflatable vehicle occupant protection device (14) includes a housing (20) defining a generally ring-shaped propellant chamber (116) extending around an axis (50) of the inflator. The housing (20) has a fluid outlet (52) for directing flow of inflation fluid out of the housing to the inflatable device (14). The propellant chamber (116) has first and second axially spaced portions (158, 159). A quantity of ignitable propellant (140) is located in the first portion (158) of the propellant chamber (116) for, when ignited, producing inflation fluid for inflating the inflatable device (14). A heat sink (160) is located in the second portion (159) of the propellant chamber (116) for cooling inflation fluid flowing from the propellant chamber. The heat sink (160) has a generally conical configuration and acts between the propellant (140) and the housing (20) to limit movement of the propellant in the housing.
