Abstract: 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.

Abstract: In the oil industry, the acoustic sounding method is a well-known technique for taking the depth measurements of particular attributes of an oil well or borehole. The method involves sending a short, sharp, clear, loud bang sound down a borehole, normally between the inside wall of the borehole casing, commonly referred to as the annulus and the outside of the production tubing string, and recording the echoes generated. One device for generating the sound needed in the acoustic sounding method is an air or gas pressurized chamber which is discharged at or near the wellhead of the borehole. The sound being generated by this device, commonly known as an acoustic generator, comes from the energy released by the equilibration of the different gas pressures.

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.
