An automotive vehicle includes a vehicle body and at least one reservoir containing a fire suppressant agent. A distribution system receives the fire suppression agent from the reservoir and conducts the agent to at least one location about the vehicle's body in response to the determination by a sensor system and controller that the vehicle has been subjected to a significant impact. The reservoir includes a multifunction valve element which controls pressure and vacuum within the reservoir during standby operation, while causing the fire suppressant agent to be directed through the distribution system if the propellant activates.

What is claimed is: 1. An onboard fire suppression system, comprising: at least one reservoir containing a fire suppressant agent; a propellant, operatively associated with said reservoir, for expelling the fire suppressant agent from the reservoir under pressure; a distribution system for receiving fire suppressant agent expelled from said reservoir and for distributing the suppressant agent; and a multifunction control valve, operatively connected with said reservoir, for maintaining pressure within said reservoir within a predetermined range during standby operation, with said control valve closing in the event that said propellant is activated, wherein said multifunction control valve comprises a vacuum responsive element, a standby pressure relief element, and a high flow closure element. 2. An onboard fire suppression system according to claim 1, wherein said control valve extends through a wall of said reservoir, with said vacuum responsive element having an inward-opening poppet, and with said standby pressure relief element having an outward-opening poppet, and with said high flow closure element comprising an outward-closing poppet responsive to high rate flow of the suppressant agent. 3. An onboard fire suppression system according to claim 2, wherein said outward closing poppet closes in response to an elevated suppressant flow rate and elevated suppressant pressure accompanying discharge of said suppressant from said reservoir. 4. An onboard fire suppression system according to claim 2, wherein said inward-opening poppet opens in the event that pressure within said reservoir falls below a predetermined minimum pressure, with said outward-opening poppet moving to an open position in the event that pressure within the reservoir exceeds a predetermined maximum static pressure, and with said high flow-responsive poppet closing in the event that pressure produced by said propellant exceeds a predetermined maximum dynamic pressure. 5. An onboard fire suppression system according to claim 2, wherein said inward-opening poppet and said outward-opening poppet are resiliently biased into normally-closed positions, with said outward-closing poppet being resiliently biased into a normally-open position. 6. An onboard fire suppression system according to claim 1, wherein said propellant is housed within said reservoir. 7. An onboard fire suppression system according to claim 1, wherein said propellant is external to said reservoir, and said multi-function control valve is located within a conduit extending between said reservoir and said propellant. 8. An onboard fire suppression system according to claim 1, wherein said multifunction control valve is contained within a filler port plug for said reservoir. 9. An onboard fire suppression system according to claim 1, wherein said reservoir comprises a fiber-reinforced resin composite. 10. An onboard fire suppression system, comprising: at least one reservoir containing a fire suppressant agent; a propellant, operatively associated with said reservoir, for expelling the fire suppressant agent from the reservoir under pressure; a distribution system for receiving fire suppressant agent expelled from said reservoir and for distributing the suppressant agent; and a multifunction control valve, operatively connected with said reservoir, for maintaining pressure within said reservoir within a predetermined range during standby operation of said fire suppression system, with said control valve comprising: a vacuum responsive element having an inward-opening poppet; and a dual-mode poppet having an outward-opening valve element for standby pressure relief, and an outward-closing valve element for shutting off flow through the multifunction control valve if the propellant is activated. 11. An onboard fire suppression system according to claim 10, wherein said outward-opening valve element and said outward-closing valve element comprise opposite ends of a unitary valve spool. 12. An onboard fire suppression system according to claim 11, wherein said inward-opening poppet cooperates with a vacuum orifice formed in said valve spool to establish a minimum pressure value for said reservoir. 13. An onboard fire suppression system according to claim 10, wherein said reservoir comprises a fiber-reinforced resin composite.
