Beschreibung
Zusammenfassung:	The invention relates to a fluid dispensing device (100) for controlling the atmosphere of a work zone (20), said device having: a first connection stage (103), comprising an intake chamber (105) which is intended to receive the incoming fluid (101) and evacuation chamber (106) which is intended to collect the outgoing fluid (102) and is separated from the intake chamber (105) by a first partitioning structure (110); and then a second dispensing stage (104), comprising a plurality of injection cells (111), which communicate with the intake chamber (105) and which are connected, respectively, to several injection points (46) provided in the work zone (20), and a plurality of extraction cells (112), which communicate with the evacuation chamber (106) and which are connected, respectively, to several extraction points (47) provided in the work zone (20), in the form of alternating angular injection sectors (A111) and angular extraction sectors (A112) defined by a second partitioning structure (114).
