ABSTRACT:
A fast-acting solenoid actuated valve assembly is disclosed which utilizes a pressure biased primary valve member and a secondary solenoid actuated valve member. The solenoid is operative to initially partially open the secondary valve member to thereby vent the primary valve pressure biasing to thereby enable opening of the primary valve. The secondary valve member is moved to a fully open position by the force generated by the initial venting of the biasing pressure. The speed of operation of the present valve assembly renders it particularly well suited for use in motor vehicle air bag assemblies. Actuating circuits are also disclosed for actuating the valve assembly.
