ABSTRACT:
A proportioning device is provided for use with a sealable chamber for unloading pulverulent material from a bulk transport system which includes a fluid inlet conduit having one terminal end in communication with the chamber for transmitting fluid into the chamber for fluidizing the pulverulent material therein, a fluid outlet conduit having one terminal end in communication with the chamber for transmitting fluidized solids therefrom. The proportioning device is in communication with the other terminal end of the fluid inlet conduit and with the fluid outlet conduit and is adapted to be connected to a source of fluid for supplying the fluid to the fluid inlet conduit and the fluid outlet conduit, the fluid proportioning device being responsive to the fluid pressures in the fluid conduits for proportioning the fluid into the fluid inlet conduit and the fluid outlet conduit to maintain a predetermined ratio between the fluid pressures in the fluid inlet conduit and the fluid outlet conduit.
