CLOSED LOOP FLUID BUFFER, BI-COMPONENT MIXING SYSTEM COMPRISING A CLOSED LOOP FLUID BUFFER AND BI-COMPONENT MIXING SYSTEM MOUNTED FOR MOVEMENT WITH A DISPENSER

摘要

A closed-loop fluid buffer for stabilizing an output pressure of a fluid supply system, in particular a bi-component mixing system, is disclosed. The fluid buffer comprises a fluid cavity having a fluid cavity volume and a fluid cavity wall, the fluid cavity having an inlet and an outlet, where the inlet is adapted to be in fluid communication with at least one fluid reservoir and the outlet is adapted to be in fluid communication with a dispensing applicator. The fluid cavity wall includes at least one flexible buffering portion to allow a volume change of the fluid cavity volume. Systems having such a fluid buffer such as a bi-component mixing system and a bi-component mixing system mounted on an x-y-mover for movement with a dispenser, as well as a method of dispensing a fluid, are also disclosed.
