    Abstract: A color changer has a common feed passage that is connected to two or more inlet passages. The common feed passage can be reverse purged in a direction that is opposite a direction of powder flow through the common feed passage. A valve element seals a supply port that connects the inlet passage to the common feed passage to eliminate dead space and form a near bore line seal. The valve element is an elastic material that expands in response to applied compressed air inside the valve element.

    Abstract: A nozzle assembly for a material application device includes an expansion chamber for slowing down the velocity of powder fed to the nozzle from a dense phase pump. The nozzle assembly includes a nozzle insert that forms the expansion chamber and provides air assist function. The nozzle includes an integral deflector, and further includes a passageway for a charging electrode so that the electrical path is routed away from the powder path, while permitting the electrode tip to be centered in the powder spray pattern from the nozzle. The nozzle also includes air wash for the electrode. The nozzle outlet orifice has a cross-sectional area that is equal to or greater than the inlet cross-sectional area so that a slow moving dense phase powder cloud is produced by the nozzle.

    Abstract: A dense phase pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided.

    Abstract: A coating powder feed method, coating powder feeding device, electrostatic powder spraycoating apparatus containing such a coating powder feeding device. The invention includes a dense phase powder pump fitted with at least one feed chamber. A control signal to create a partial vacuum in the feed chamber is generated no earlier than simultaneously with, preferably by a predetermined delay time after, a control signal opening a powder intake valve of the feed chamber, as a result of which the beginning of partial vacuum buildup in the feed chamber shall take place no earlier than simultaneously with the initial opening of the powder intake valve or by a defined time delay after the opening of the powder intake valve.
