Abstract: The current invention is a device for controlling, or regulating, fluid pressure from a source of unregulated fluid pressure. Without being bound by theory, the invention controls output fluid pressure by balancing the pressures and/or forces placed upon a shuttle that is located in a chamber; the chamber having an inlet for fluid of an unregulated fluid pressure and an outlet for dispensing fluid with a controlled, or regulated, fluid pressure. The invention controls the fluid communication between the chamber inlet and outlet through a valve; with the valve inlet being located on or in the shuttle. As a result one unique aspect of the invention is that, unlike conventional fluid controllers and regulators, the invention does not require a diaphragm to control fluid pressures as the invention utilizes the various forces on, and resultant movements with relation to the chamber of, the shuttle to control the output fluid pressure.
