Abstract:
1. A gas pressure regulator comprising: a body defining a proximal end portion, a distal end portion, and a central portion having a longitudinal axis extending therethrough; an inlet disposed proximate the distal end portion of the body, the inlet defining an inlet axis extending therethrough, the inlet having an entry portion and a bottom portion, and the inlet axis being offset from the longitudinal axis; a pocket integrally formed in the body and disposed proximate the bottom portion of the inlet and centrally aligned with the inlet axis, wherein the pocket is in communication with the inlet via a tapered inlet portion of an opening of the pocket, the tapered inlet portion reducing the inlet to the opening having a diameter less than the diameter of the entry portion of the inlet; a cavity disposed within the central portion of the body and defining an upper portion and a lower portion, the cavity centrally aligned with the longitudinal axis; a channel extending between the inlet and the cavity; and a guide disposed within the lower portion of the cavity and the guide defines an exterior surface, wherein a flow of gas through the gas pressure regulator extends through the inlet and flows in a first direction, the first direction extending into the pocket, the flow then changes direction to flow through the channel in a second direction, and changes direction again to flow through the cavity, and the flow of gas changes direction to go through the channel before reaching the pocket and impacts the guide and flows around the exterior surface of the guide and along the exterior surface, prior to changing direction to flow through the cavity, and wherein a total angular change in flow direction of the flow of gas from the first direction to the second direction relative to the first direction is less than or equal to 90°.
