  • Publication number: 20150101674
    Abstract: A pressure regulator having an outlet port, an inlet port, and a vent port, and a regulator piston having an internal passage in constant fluid communication with the outlet port. The regulator piston has a first position where the passage is in fluid communication with the inlet port and not the vent port, a second position where the passage is not in fluid communication with either the inlet port or the vent port, and a third position where the passage is in fluid communication with the vent port and not the inlet port. The pressure regulator also has a spring piston in mechanical communication with the regulator piston that is biased to exert a force on the regulator piston sufficient to move the regulator piston between the first, second, and third positions. The spring piston is enclosed in a spring housing with an internal area maintained at about atmospheric pressure.

  • Publication number: 20150075635
    Abstract: A system actively regulates the fluid pressure entering the pump of a fluid-dispensing system to provide a more uniform fluid flow exiting the pump. The pump is supplied with fluid from a pressurized reservoir (e.g., that is pressurized from an external air source, or by mechanical or electrically-driven pressurization). A pressure sensor monitors the fluid pressure in the fluid supply line between the reservoir and pump. A controller receives this fluid pressure reading as an input to regulate the pressurization of the reservoir. Optionally, a second pressure sensor can be used to monitor the fluid pressure at the pump exit to provide an additional input for the controller.
