This pressure regulator is specifically designed to operate with a portable compressed gas cartridge thus reducing the high vapor pressure found in compressed gas cartridges down to a substantially consistent outlet pressure. Due to the nature of the crowded regulator art, the soon to be embodied pressure regulator has been specifically embodied for use in the portable compressed gas cartridge harnessing art and this specific use is carried into the claims. Exemplified in the pressure regulator embodiments is a reduced amount of components over existing designs. Additionally, safety and reliability features have been integrated into the design and will shortly be taught in the following paragraphs. A burp-off feature in all embodiments will be exemplified that vents back-pressure spikes as well as a method of adjusting the burp-off back-pressure spikes independent of regulated pressure in some embodiments.

I claim: 1. A pressure regulation device adaptable to a compressed gas cartridge capable of delivering a substantially consistent outlet pressure, comprising: a body comprising an externally threaded top portion and formed to include an internal piston bore, a negative vent interconnecting with said piston bore and extending outwardly through said body, a valve chamber extending inwardly through a bottom portion, and a plunger channel interconnecting said piston bore and said valve chamber; a lance housing disposed in said valve chamber and terminating with a cartridge-piercing lance and a deformable seal situated around said cartridge-piercing lance; a first spring disposed within said valve chamber and comprising a first end and a second end, wherein said first end of said first spring is in contact with said lance housing; a valve ball in contact with the second end of said first spring; a piston moveably disposed within said piston bore, wherein said piston is formed to include an exit conduit formed to include a lumen extending therethrough, wherein said lumen communicates with said plunger channel; a plunger extending downwardly from said piston and comprising a distal end, wherein said distal end contacts said valve ball; a cap rotatably and threadedly disposed around said top portion of said body; a second spring having a first end and a second end, wherein said first end of said second spring contacts said cap, and wherein said second end of said second spring urges said piston downwardly in said piston bore with a preload force such that said piston blocks said negative vent; wherein introduction of a back pressure into said piston bore greater than said preload force causes said piston to move upwardly thereby exposing said negative vent. 2. The pressure regulation device of claim 1 further comprising male threads externally disposed on said bottom portion of said body. 3. The pressure regulation device of claim 2, further comprising a cartridge-retaining container removeably attached to said bottom portion. 4. The pressure regulation device of claim 1, wherein said lance housing comprises a female 3/8-24 Unified National Fine thread. 5. The pressure regulation device of claim 1, wherein: said plunger is threadedly attached to said piston; said plunger comprises an adjustable height; said adjustable plunger height permits tuning said regulator to vent a desired back-pressure independent of said preload force. 6. The pressure regulation device of claim 1, further comprising: a body formed to include a plurality of negative vents interconnecting said piston bore and extending outwardly through said body; wherein said second end of said second spring urges said piston downwardly in said piston bore with a preload force such that said piston blocks said plurality of negative vents; wherein introduction of a back pressure into said piston bore greater than said preload force causes said piston to move upwardly thereby exposing said plurality of negative vents.
