The invention relates to a closed loop fluid buffer (1, 136) for stabilizing an output pressure of a fluid supply system, in particular a bi-component mixing system (100), In particular, it is suggested that the buffer comprises a fluid cavity (10) having a fluid cavity volume and a fluid cavity wall, said fluid cavity (10) having an inlet (12, 138) and an outlet (14, 140), wherein said inlet (12, 138) is adapted to be in fluid communication with at least one fluid reservoir (118, 122) and said outlet (14, 140) is adapted to be in fluid communication with a dispensing applicator (102), wherein said fluid cavity wall comprises at least one flexible buffering portion (18) to allow a volume change of the fluid cavity volume. The invention further relates to systems having such a buffer such as a bi- component mixing system (100) comprising a closed loop fluid buffer (136) and bi-component mixing system (100) mounted on an x-y-mover (500) for movement with a dispenser, and to a method of dispensing a fluid. |
