Abstract
A reservoir for powdery media, in particular powder coating, comprises a housing having at least one inlet and an outlet. A fluidising floor of porous, air-permeable material is located in the interior of the housing at a distance from its base. In this way a pressure chamber which is chargeable with compressed air is formed between the fluidising floor and the base of the housing. In order to reduce the quantity of compressed air required for fluidising and to keep low the mechanical stress imposed on the powdery medium when in the fluidised state, the cross-section of the housing narrows downwardly towards the fluidising floor. In addition, this shape of the housing generates turbulence in the fluidised powdery material.
