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. |
