Device and installation for injecting matter, particulate matter in particular, into an enclosure, and associated method. The device for injecting matter into a reaction enclosure in a treatment method using pressurized water comprises a pressurizing capacity ( 24 ) having an inner volume in which a mobile assembly ( 29 ) is arranged, e.g. a bellows which compartments it sealingly into two variable volumes, namely a pressurizing capacity ( 32 ) and a hydraulic pressurizing capacity ( 34 ). The variable, hydraulic pressurizing capacity of this device is connected to the outlet ( 15 ) of the aqueous phase of a liquid/gas separator ( 14 ) which separates the liquid and gaseous phases of an effluent leaving the reaction enclosure ( 2 ).
