US 2016/0256883 A1 · LIQUID DISPENSING SYSTEM WITH IMPROVED PRESSURE CONTROL

Abstract

A liquid dispensing system is provided. The liquid dispensing system comprises a fluid applicator with an inlet and an outlet. The liquid dispensing system also comprises a fluid flow path comprising an inlet configured to couple to a fluid source on a first end, and the fluid applicator on a second end. The liquid dispensing system also comprises a pump system configured to drive flow of fluid from the fluid source along the fluid flow path to the fluid applicator. The liquid dispensing system also comprises a pressure relief system. The pressure relief system comprises a return line. The pressure relief system also comprises a pressure relief valve. The pressure relief system when actuated, is configured to actuate a pressure relief valve such that the return line receives a portion of fluid within the fluid flow path in response to a detected pressure proximate the fluid applicator.
