ABSTRACT:
An air bag inflator which includes a gas source and a gas outlet opening for allowing flow of gas from the gas source into the air bag wherein the flow of gas is controlled with a valve assembly including a piston disposed in a cylinder and features a piston which has a pintle shaped surface against which the gas acts to cause movement of the piston in a first direction in the cylinder to provide an increased flow of gas through the gas outlet opening and further includes a spring disposed in the path of movement of the piston so that as the piston moves in the cylinder the spring provides resistance to the movement of the piston.
