A powder metering apparatus for making available a powder, in particular for powder coating, and which comprises a metering pump with a rotatably driven metering disk arranged between two lateral plates. The metering pump includes an inlet, through which it receives a powder-air mixture, and an outlet that connects via a suction tube to an injector pump. From the outlet, the powder-air mixture conveyed by means of the metering disk to the outlet is sucked out by a vacuum flow that is generated in the injector pump and enters the metering pump via a suction inlet opening, and the powder-air mixture is then supplied to a consumer.

[ That which is claimed is:] [1.]1. A powder metering apparatus which dispenses a powder-air mixture to a consumer, comprisinga metering pump which includes a rotatably driven metering disk mounted between and immediately adjacent each of two lateral plates, with said metering disk having metering chambers distributed over its circumference, an inlet through which a powder-air mixture is serially supplied to the metering chambers of the rotating metering disk, and an outlet from which the powder-air mixture is serially removed from the metering chambers of the rotating metering disk,an injector pump connected to the outlet of said metering pump via a suction tube for generating a suction in the suction tube which serves to generate a vacuum flow which serially removes the powder-air mixture from the metering chambers of the rotating metering disc and delivers the powder-air mixture to a consumer, anda controller, by which the injector pump can be controlled in a pressure-regulated manner as a function of the rotational speed of the metering disk of the metering pump.
