| abstract |
A gas pressure regulator for use with gas delivery systems is provided. The gas pressure regulator includes, in one form, an inlet with an entry portion and a bottom portion. A pocket is disposed proximate the bottom portion of the inlet, and a cavity is disposed within a central portion of the gas pressure regulator. A guide is disposed within a lower portion of the cavity, and a flow of gas through the gas pressure regulator extends through the inlet, changes direction to flow through the cavity, and the flow of gas changes direction to impact the guide prior to flowing through the cavity. The pocket and the guide reduce the amount of particles capable of reaching internal components of the gas pressure regulator, resulting in low sensitivity and high fault tolerance to ignited particles coming through the gas pressure regulator in the event of accidental particle contamination. |
