Abstract

A thermal energy machining ("TEM") machine gas handling system in which the improvement is a fluid-controlled pressure regulation subsystem for controlling the dispensing of a TEM process gas via the regulation of the pressure of the TEM process gas. Such subsystems include a pressure regulator, a pressure transducer, and a digital controller working in combination to control the process gas outlet pressure of the pressure regulator. The pressure regulator's diaphragm that controls the valve that regulates the process gas outlet pressure is mechanically acted upon by the piston of a pneumatic or hydraulic cylinder. Controlling the pneumatic or hydraulic cylinder regulates the output pressure of the process gas. The pressure transducer and the digital controller work in combination to adjust the feed pressure of the pneumatic or hydraulic cylinder, which in turn regulates the pressure of the process gas at the outlet of the pressure regulator.
