Liquid dispensing system with improved pressure control

A liquid dispensing system (100) is provided. The liquid dispensing system (100) comprises a fluid applicator (130) 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 (110) on a first end, and the fluid applicator (130) on a second end. The liquid dispensing system (100) also comprises a pump system (120) configured to drive flow of fluid from the fluid source (110) along the fluid flow path to the fluid applicator (130). The liquid dispensing system (130) also comprises a pressure relief system (132). The pressure relief system (132) comprises a return line (126). The pressure relief system (132) also comprises a pressure relief valve (216). The pressure relief system (132) when actuated, is configured to actuate a pressure relief valve (216) such that the return line (126) receives a portion of fluid within the fluid flow path in response to a detected pressure proximate the fluid applicator (130). 提供了种液体分配系统(
