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.

What is claimed is: 1. A thruster gas control mechanism, comprising: (a) a shell, the shell having opposing walls, the opposing walls being parallel to each other to form two parallel walls, the shell having a gas entrance, a gas exit, a parallel wall of the shell having a plunger opening, the shell having a hollow interior; (b) first and second supports within the hollow interior; (c) two parallel baffles, the two baffles being able to slide between the first and second supports; a first channel being formed between an interior side of a first parallel wall and the first baffle and between a first side of each of the first and second supports, the first channel having an upstream end and a down stream end, a second channel being formed between an interior side of a second parallel wall and the second baffle, and between a second side of each of the first and second supports, the second channel having an upstream end and a down stream end, the first baffle being able to be positioned to close the downstream end of the first channel and the second baffle being able to be positioned to close the downstream end of the second channel; (d) a plunger passing through the two baffles and connected to the two baffles, the plunger also passing through the plunger opening of the shell; and (e) an armature, the armature being able to be positioned to close the upstream end of the first channel and alternately being able to be positioned to close the upstream end of the second channel. 2. A thruster gas control mechanism, comprising: (a) a shell, the shell having first and second parallel walls, the shell having a gas entrance and a gas exit; (b) first and second baffle supports, the first and second baffle supports being separated from the first and second parallel walls, a space between the first baffle support and a first parallel wall forming a portion of a first channel, a space between the second baffle support and the first parallel wall forming another portion of the first channel, a space between the first baffle support and the second parallel wall forming a portion of a second channel, a space between the second baffle support and the second parallel wall forming another portion of the second channel; the first and second channels being connected between the gas entrance and the gas exit, each of the first and second baffle supports having a smooth surface, the smooth surfaces being parallel to each other, the smooth surfaces being perpendicular to the parallel walls; (c) first and second baffles located between the smooth surfaces of the first and second baffle supports; the first and second baffles being spaced from the first and second parallel walls, a space between the first baffle and the first parallel wall forming a portion of the first channel and a space between the second baffle and the second parallel wall forming a portion of the second channel, the baffles being rectangular parallelepiped, the baffles having parallel sides, the parallel sides being perpendicular to the smooth surfaces; and (d) a plunger, the plunger being connected to the baffles, the plunger passing through the parallel sides of the baffles, a longitudinal axis of the plunger being perpendicular to the parallel walls, the plunger also passing through a parallel wall. 3. A thruster gas control mechanism, comprising: (a) a rectangular shell having a single gas entrance, a single gas exit, a plunger opening and a hollow central rectangular interior; (b) a central body within the hollow central rectangular interior, the central body comprising a first support and a second supports; (c) two parallel baffles, the two parallel baffle being between the first and second supports; (d) a plunger, the plunger passing through the two baffles, the central body and two baffles forming a first channel with a first interior side of the rectangular shell and forming a second channel with a second interior side of the rectangular shell, the first and second interior sides being opposite to each other, the plunger passing through the plunger opening of the rectangular shell, the first baffle being able to be positioned to close a downstream end of the first channel and the second baffle being able to be positioned to close a downstream end of the second channel; and (e) an armature being able to be positioned to partially close an entrance portion of the first channel and to partially close an entrance portion of the second channel.
