Abstract

The invention relates to a metering installation for powder pigments, having an arrangement for supplying the powder pigments into a weighing container of a weighing arrangement. The weighing container may be emptied into a pneumatic conveying conduit which leads into a consuming unit, if appropriate, via an intermediate store. The conveying arrangement has a hopper-like pressure container which can be subjected to the action of compressed air. The pressure container has a closure at the base and a laterally curved outlet connector. An injector tube, which can be subjected to the action of compressed air and has lateral exit openings for the compressed air, extends axially into the outlet connector.
