ABSTRACT:
A thruster gas control mechanism for controlling a flow of thrust gas through a gas nozzle, the mechanism having a plunger movable into and out of the gas nozzle, the plunger being connected to two movable baffles. The two baffles form two channels with two side walls of the mechanism. A movable armature controls flow of other thruster gas through either of the two channels, or through both channels, to cause the baffles and plunger to move toward or away from the gas nozzle, and causing the plunger to move into or out of the gas nozzle.
