Patent number: 7914040Abstract: A gas generating system incorporating a gas flow control mechanism including opposed wall portions defining a cavity for slidably receiving a support member therein. A gas exit passage is exterior of the cavity and in fluid communication with the cavity. An opening in one wall portion enables fluid flow into the cavity. An opening in another wall portion enables a fluid flow from the cavity into the gas exit passage. A seal prevents fluid flow into the cavity when the seal is supported against a force exerted by the fluid. A support member slidably received within the cavity supports the seal against the fluid force. A mechanism is provided for moving the support member from a first position supporting the seal to a second position wherein the seal is unsupported by the support member, enabling failure of the seal and flow of the fluid.Type: GrantFiled: April 28, 2008Date of Patent: March 29, 2011Assignee: TK Holdings, Inc.Inventor: Bruce A.
