Zusammenfassung:	A coating device for applying a coating agent to the surface of a workpiece. The coating device includes a frame with a workpiece receptacle, a coating agent source and a rotary unit which is rotatable in relation to the frame. The rotary unit has a pump and a plurality of spray units, with the pump on the suction side being connected to the coating agent source by a fluid-conducting rotary joint connection. The rotary unit has a pneumatic valve device, and the spray units have in each case one compressed air controlled valve for controlling the delivery of coating agent. The inlet side of the valve is connected to the compressed air source by a fluid-conducting rotary feedthrough, which simplifies the overall construction of the coating device by providing a pneumatic connection between the compressed air source and the rotary unit that is independent of the rotation angle.
