The invention relates to a device for guiding powdery fluidic media, in particular powder paint, comprising a receptacle (12) which is provided with an inner chamber (26) for the media which is to be guided, and from where the medium is suctioned via a connection channel (48) which can be closed by a valve body (82). The connection channel (48) and the valve body (82) comprise, respectively, an upper end area (64, 102). Said upper end areas are formed in such a manner that an annular Venturi nozzle (107) is formed therebetween which is used as a pump. The valve body (82) is inserted in a sealed manner in the end region (64) of the connecting channel (48) by means of a sealing section (92) when in the closed position thereof and comprises a conveyor gas channel (114, 104, 106, 108) which can be impinged upon by conveyor gas, through which the conveyor gas can be guided to the connection channel (48) in the vicinity of the sealing section (92), essentially, in the direction of flow of the medium.
L'invention concerne un dispositif pour acheminer des substances fluidisées pulvérulentes, notamment une poudre de revêtement, comprenant un réservoir (12) pourvu d'une chambre intérieure (26) qui est destinée à la substance à acheminer et à partir de laquelle la substance est aspirée par l'intermédiaire d'un canal de raccordement (48) pouvant être obturé par un corps de soupape (82). Le canal de raccordement (48) et le corps de soupape (82) présentent chacun une zone terminale supérieure (64,102). Ces zones terminales supérieures sont façonnées de façon à former entre elles un tube de Venturi annulaire (107) servant de pompe. Le corps de soupape (82) est inséré de manière étanche dans la zone terminale (64) du canal de raccordement (48) par l'intermédiaire d'une partie d'étanchéité (92), lorsqu'il se trouve en position fermée, et présente un canal de gaz de transport (114, 104, 106, 108) alimenté en gaz de transport, à travers lequel le gaz de transport peut être acheminé au canal de raccordement (48) à proximité de la partie d'étanchéité (92) sensiblement dans le sens d'écoulement de la substance.
