A fluid pressure regulating apparatus is provided. The apparatus includes a chamber having a first bore diameter, a second bore diameter, a fluid inlet for receiving fluid at an unregulated pressure, and a fluid outlet for discharging fluid at a regulated pressure. A shuttle assembly is located in the chamber, the shuttle assembly including a valve that is in fluid communication with both the fluid inlet and the fluid outlet, and a first sealing member located at an upper portion of the shuttle assembly and a second sealing member located at a lower portion of the shuttle assembly. An unregulated pressure zone communicates with the fluid inlet, a regulated pressure zone communicates with the fluid outlet and a fluid pressure control zone communicates with a portion of the shuttle assembly, the fluid pressure control zone controlling the regulated pressure at the fluid outlet.

The fluid pressure regulating apparatus of claim 1, where the third Schrader valve is operated by the shuttle assembly. 5. The fluid pressure regulating apparatus of claim 1, further comprising a fluid pressure setting element abutting the shuttle assembly, the fluid pressure setting element structured to adjustably set a fluid pressure of the fluid pressure regulating apparatus. 6. The fluid pressure regulating apparatus of claim 1, where the fluid pressure regulating apparatus can regulate a fluid selected from a group consisting of: a liquid and a gas, and a combination of a liquid and a gas. 7. A fluid pressure regulating apparatus, comprising: a chamber comprising a first bore diameter, and a second bore diameter adjacent and concentric to the first bore diameter, the second bore diameter larger than the first bore diameter;a fluid inlet for receiving a fluid at an unregulated pressure;a fluid outlet for discharging the fluid at a regulated pressure;a shuttle assembly located in the chamber, the shuttle assembly moveable during operation of the fluid pressure regulating apparatus, the shuttle assembly comprising: a) a first Schrader valve that is in fluid communication with both the fluid inlet and the fluid outlet, the first Schrader valve including a pin element that moves relative to the shuttle assembly and abuts an adjustable pressure release element to open the first Schrader valve when the shuttle assembly moves during operation;b) a first sealing member located at an upper portion of the shuttle assembly; andc) a second sealing member located at a lower portion of the shuttle assembly;an unregulated pressure zone communicating with the fluid inlet;a regulated pressure zone communicating with the fluid outlet;a fluid pressure control zone communicating with a portion of the shuttle assembly, the fluid pressure control zone including a plurality of springs that communicate with a portion of the shuttle assembly, the fluid pressure control zone and the plurality of springs structured to variably control the regulated pressure at the fluid outlet;a second Schrader valve in fluid communication with the fluid outlet and a fluid outlet relief vent; anda third Schrader valve in communication with the fluid inlet and a fluid inlet relief vent. 8. The fluid pressure regulating apparatus of claim 7, where a hydraulic area of the shuttle assembly at the regulated pressure zone, minus an area of the first valve, is equal to a hydraulic area of the shuttle assembly at the fluid pressure control zone. 9. The fluid pressure regulating apparatus of claim 7, where the fluid is selected from a group consisting of: a gas and a liquid, and a combination of both a liquid and a gas. 10. The fluid pressure regulating apparatus of claim 7, where the regulated pressure at the fluid outlet is set by a moveable fluid pressure adjuster. 11. The fluid pressure regulating apparatus of claim 7, where the regulated pressure at the fluid outlet is set by a hydraulic pressure acting on the shuttle assembly. 12. The fluid pressure regulating apparatus of claim 7, further comprising: an upper collar adjacent to the first sealing member and a lower collar adjacent to the second sealing member; anda sidewall located on both the upper collar and the lower collar, each sidewall adjacent to the chamber, with each sidewall angled relative to the chamber.
