Precision gas regulator adjustment mechanism utilizing stepper motor control

A precision gas regulator adjustment mechanism, comprising:

• a cylindrical adjust screw having external threads configured for threading into a base positioned atop a plunger of a gas regulator, said adjust screw further comprising internal threads;
• a drive screw configured for threading into the internal threads of the adjust screw, said drive screw contacting the plunger when threaded into the adjust screw;
• a stepper motor paddle inserted into a slot at the top of the drive screw, wherein activation of the stepper motor causes rotation of the stepper motor paddle, thereby rotating the drive screw within the adjust screw;
• a radial protrusion on a top surface of the drive screw, and a vertical protrusion on a top surface of the adjust screw, said radial protrusion and vertical protrusion configured to limit rotation of the drive screw within the adjust screw;
• and
• whereby rotation of the stepper motor paddle adjusts a position of the drive screw within the adjust screw, thereby adjusting a position of the plunger of the gas regulator.
