A gas pressure regulator adapted for being mounted to a gas cylinder is provided. The gas pressure regulator includes a body defining a front portion and opposed side portion and a plurality of gas pressure indicators mounted to the front portion of the body. A bonnet is mounted to an exterior portion of the body, and a pressure adjustment knob is mounted to one of the side portions of the body, proximate the bonnet, and horizontally relative to a longitudinal axis of the pressurized gas cylinder. An energy absorbing device is operatively engaged with the pressure adjustment knob and the bonnet, the energy absorbing device being capable of absorbing energy from impact loads imposed on the pressure adjustment knob.

1. A gas pressure regulator adapted for being mounted to a gas cylinder, the gas pressure regulator comprising: a body defining a front portion and opposed side portions;a plurality of gas pressure indicators mounted to the front portion of the body;a bonnet mounted to an exterior portion of the body;a pressure adjustment knob mounted to one of the side portions of the body, proximate the bonnet, and horizontally relative to a longitudinal axis of the pressurized gas cylinder; andan energy absorbing device operatively engaged with the pressure adjustment knob and the bonnet, the energy absorbing device being capable of absorbing energy from impact loads imposed on the pressure adjustment knob;wherein the energy absorbing device comprises a series of members that progressively slow a velocity of the pressure adjustment knob under impact loads, and the series of members comprise: a first stage member defining an arcuate wall that extends along an interior central portion of the pressure adjustment knob and an end portion;a second stage member defining a plurality of walls positioned around an inner periphery of the pressure adjustment knob;wherein the arcuate wall defines a specific thickness to buckle under a load limit, thereby allowing the second stage member to engage the bonnet to slow a velocity of the pressure adjustment knob under impact loads. 2. The gas pressure regulator according to claim 1, wherein the first stage member is further defined as an arcuate wall that extends along the interior central portion of the pressure adjustment knob to an end portion of the first stage member. 3. The gas pressure regulator according to claim 2, wherein the arcuate wall defines the specific thickness along the interior central portion and the specific thickness buckles when the loads reach a limit. 4. The gas pressure regulator according to claim 3, wherein the specific thickness is along the interior central portion adjacent the end portion. 5. The gas pressure regulator according to claim 1, wherein the plurality of walls of the second stage member are further defined as a plurality of angled walls positioned around the inner periphery of the pressure adjustment knob. 6. The gas pressure regulator according to claim 5, wherein the plurality of angled walls are inclined inward toward the interior central portion. 7. The gas pressure regulator according to claim 6, wherein the plurality of angled walls engage the bonnet when the first stage member buckles and the angled walls progressively wedge tighter onto the bonnet deforming the inner periphery of the pressure adjustment knob outward. 8. The gas pressure regulator according to claim 1, wherein the series of members further comprise: a third stage member positioned around the interior central portion of the pressure adjustment knob;wherein the first, second, and third stage members progressively engage the bonnet to slow the velocity of the pressure adjustment knob under impact loads. 9. The gas pressure regulator according to claim 8, wherein the third stage member is disposed between the first stage member and the second stage member. 10. The gas pressure regulator according to claim 9, wherein the third stage member defines a plurality of pegs. 11. The gas pressure regulator according to claim 10, wherein the series of members progressively slow a velocity of the pressure adjustment knob under impact loads of approximately 8,000 to 9,000 pounds-force. 12. The gas pressure regulator according to claim 1, wherein the first stage member is adjacent the bonnet, the second stage member is spaced a distance along the longitudinal axis from the bonnet. 13. A method for absorbing energy from an impact load by a gas pressure regulator adapted for being mounted to a gas cylinder comprising a body defining a front portion and opposed side portions and a bonnet mounted to an exterior portion of the body and a pressure adjustment knob mounted to one of the side portions of the body, proximate the bonnet, and horizontally relative to a longitudinal axis of the pressurized gas cylinder, the method comprising: providing an energy absorbing device within the pressure adjustment knob having a series of members that progressively slow a velocity of the pressure adjustment knob under the impact load, the series of members comprise: a first stage member defining an arcuate wall around the interior central portion and the arcuate wall having a specific thickness; anda second stage member defining a plurality of angled walls positioned around an inner periphery of the pressure adjustment knob;imparting an impact load on the pressure adjustment knob;engaging the first stage member against the bonnet under the impact load;buckling the first stage member at the specific thickness under a load limit and engaging the second stage member against the bonnet to slow a velocity of the pressure adjustment knob under impact loads. 14. The method according to claim 13, further comprising wedging the angled walls around the bonnet to deform the inner periphery of the pressure adjustment knob generally outward around the bonnet to slow the velocity of the pressure adjustment knob under impact loads. 15. The method according to claim 14, wherein the series of member further includes a third stage member position around the interior central portion of the pressure adjustment knob. 16. The method according to claim 15, further comprising engaging the third stage member against the bonnet after the plurality of angles walls have wedge onto the bonnet. 17. The method according to claim 16, wherein the third stage member further comprises a plurality of pegs spaced around the interior central portion of the pressure adjustment knob. 18. The method according to claim 17, further comprising deforming the plurality of pegs around the bonnet to continue to slow the velocity of the pressure adjustment knob under the impact load. 19. The method according to claim 18, wherein the impact load is further defined between 8,000 to 9,000 pound-force. 20. The method according to claim 18, wherein the series of member deform around and progressively engage with the bonnet to slow the velocity of the pressure adjustment knob under the impact load to reducing damage to the gas pressure regulator and gas cylinder.
