1. A gas generator comprising:
- a housing comprising a base and a cap fixed to said base;
a divider separating said housing into a first combustion chamber and a second combustion chamber, wherein said divider prevents sympathetic actuation of said second combustion chamber when said first combustion chamber is actuated, said divider including a peripheral lip extending therearound, the peripheral lip having an outer peripheral surface; and
a filter defining an inner wall within said housing, said outer peripheral surface of the peripheral lip of the divider being slidably engaged with said inner wall upon actuation of said first and second combustion chambers.

Abstract
A gas generator is provided that contains a housing containing a base and a cap fixed to the base; a divider separating the housing into a first combustion chamber and a second combustion chamber, wherein the divider prevents sympathetic actuation of the second combustion chamber when the first combustion chamber is actuated; and an inner wall within the housing, the divider slidably engaged with the inner wall upon actuation of the first and second combustion chambers. Accordingly, a valve assembly of the present invention generally contains a movable divider that substantially seals an enclosure thereby defining a secondary combustion chamber within the gas generator.

12. A gas generator comprising:
-
a housing comprising a base and a cap fixed to said base; a movable divider separating said housing into a first combustion chamber and a second combustion chamber, said movable divider including a peripheral lip, the peripheral lip having an outer peripheral surface; an enclosure seated within said housing and at least partially enclosing said second combustion chamber, wherein said movable divider is seated against said enclosure and substantially seals said second combustion chamber prior to actuation of said second combustion chamber; and wherein a filter defines an inner wall within said housing, wherein the outer peripheral surface of the peripheral lip of the movable divider is slidably engaged with said inner wall upon actuation of said first and second combustion chambers. - View Dependent Claims (13, 14, 15, 16)

17. A gas generator comprising:
-
a housing comprising a base and a cap fixed to said base; a valve assembly separating said housing into a first combustion chamber and a second combustion chamber, said second combustion chamber operably independent of said second combustion chamber, wherein said valve assembly prevents fluid and thermodynamic communication between said first and second combustion chambers prior to actuation of said second combustion chamber, and wherein said valve assembly includes a movable divider separating said housing into said first combustion chamber and said second combustion chamber, the movable divider including a peripheral lip, the peripheral lip having an outer peripheral surface; and a filter defining an inner wall within said housing, wherein the outer peripheral surface of the peripheral lip of the movable divider is slidably engaged with said inner wall upon actuation of said first and second combustion chambers. - View Dependent Claims (18, 19, 20)
