SYSTÈME DE RÉGULATION DE LA PRESSION D'UN FLUIDE POUR SYSTÈMES DISTRIBUTEURS DE FLUIDES

摘要

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.
