Injection termination feature

摘要

In an inflator of a vehicle safety restraint system utilizing liquid propellant as the inflation gas generator, decomposition of residual liquid propellant within the inflator produces undesirable gases which can result in unacceptable inflator effluent. The injection termination features of the present invention are formed onto an encapsulation or plug of a regenerative piston inflator. Upon completion of the piston stroke, the injection termination feature makes contact with the injection ports and plugs the injection ports to prevent combustion and decomposition reactions from propagating through the piston.
