An inflator ( 14 ) for an inflatable vehicle occupant protection device ( 12 ) has a housing ( 20 ). A propellant charge ( 240 ) in the housing ( 20 ) is actuatable to provide inflation fluid for inflating the device ( 12 ). The housing ( 20 ) has an end wall ( 42 ) and a side wall ( 44 ). The side wall ( 44 ) has a fluid passage ( 55 ) for directing flow of inflation fluid to the device ( 12 ). A flow control member ( 16 ) extends over the end wall ( 42 ) and the side wall ( 44 ) and has a movable portion ( 300 ) at least partially blocking the fluid passage ( 55 ). The control member ( 16 ) has an outlet opening ( 288 ) located over the end wall ( 42 ). The movable portion ( 300 ) moves as the pressure of inflation fluid acting on it increases upon inflator actuation to control the pressure in the housing ( 20 ) and to direct inflation fluid toward the outlet opening ( 288 ).
