Abstract: The present invention relates to a spray-coating gun for the spray coating of objects with coating powder. The front end region of the spray-coating gun has a coating-powder spray head and the opposite, rear end region of said spray-coating gun has a coating-powder connection and at least one compressed-gas connection. Coating powder can be supplied via the coating-powder connection to a coating-powder channel extending to the coating-powder spray head, while compressed gas can be supplied via the at least one compressed-gas connection to at least one compressed-gas channel extending to the front end region of the spray-coating gun.

Abstract: The invention relates to a separating powder filter, particularly for supplying different types and/or sorts of powder, as selected, to a powder delivery device. The separating powder filter comprises the following: a first powder inlet, at least one additional, second powder inlet, and a powder outlet. Either the first powder inlet or the at least one second powder inlet can be fluidically connected to the powder outlet of the separating powder filter.

Abstract: The invention relates to a powder supply device for a powder coating system having at least one powder container (24), which has a powder chamber (22), and having at least one powder dispensing device, which is connected or can be connected to a powder dispensing channel (13) opening into the powder chamber (22) via a powder dispensing opening (36), in order to extract coating powder from the powder chamber (22) during powder coating operation of the powder coating system. In order to achieve as homogeneous and effective a powder conveyance as possible using the powder supply device according to the invention, the at least one powder dispensing device is designed as a powder dense flux pump (4), in particular as a single-chamber powder dense flux pump (200).

Abstract: The invention relates to a jet-receiving nozzle for a powder-delivery injector with an arresting region on the injector side and a connecting region remote from the injector, the arresting region having a configuration preventing incorrect connection. The invention also relates to a powder-delivery injector for delivering a powder-air mixture, the powder-delivery injector having an accepting channel for accepting a jet-receiving nozzle.

Abstract: The invention relates to a nozzle (1) for atomizing coating materials, in particular coating powder, wherein the nozzle (1) comprises a housing (10), which has a first, inlet-side opening (11) and a second, outlet-side opening (12), and the openings are connected to each other by means of a passage channel (13). The housing (10) has an inner housing part (20), which defines the passage channel (13), and an outer housing part (30), which is designed to detachably connect the nozzle (1) to a coating device. According to the invention, in order to optimize the production process for the nozzle and to reduce costs, the inner housing part (20) and the outer housing part (30) are designed as separate individual pieces.

Abstract: The present invention relates to a spray-coating gun (1) for the spray coating of objects with coating powder. The front end region of the spray-coating gun (1) has a coating-powder spray head (5) and the opposite, rear end region of said spray-coating gun has a coating-powder connection (12) and at least one compressed-gas connection (13, 14). Coating powder can be supplied via the coating-powder connection (12) to a coating-powder channel (11, 26) extending to the coating-powder spray head (5), while compressed gas can be supplied via the at least one compressed-gas connection (13, 14) to at least one compressed-gas channel (9, 28; 10, 29) extending to the front end region of the spray-coating gun (1).

Abstract: The invention relates to a device for pneumatically conveying powder, the device having an injector with a conveying gas connection and a metering gas connection as well as a powder intake channel connected in terms of flow to the injector. To achieve the effect that the powder conveying device can be effectively flushed through in the cleaning mode of said device, it is provided according to the invention that a purging gas connection, which is connected or can be connected to a purging gas line, is provided between the negative pressure region of the injector and the powder intake opening of the powder intake channel for the feeding, as and when required, of purging gas, in particular compressed purging air. Furthermore, a shut-off element is assigned to the purging gas connection to prevent purging gas from being able to escape from the powder output opening of the powder intake channel.

Abstract: The invention relates to a powder pump (100; 100?) for conveying coating powder, the powder pump (100; 100?) having a powder chamber (10; 10?) with a casing tube (1; 1?) and a gas-permeable filter element (2; 2?) arranged inside the casing tube (1; 1?) a first pinch valve (3; 3?), connected to the intake-side end region of the powder chamber (10; 10?), and a second pinch valve (4; 4?), connected to the delivery-side end region of the powder chamber (10; 10?). In order to achieve the effect that the powder pump (100; 100?) can be maintained with relatively little effort, according to the invention a first connection element (6; 6?) is provided, connected to the first pinch valve (3; 3?) and fitted onto or inserted into the intake-side end region of the powder chamber (10; 10?). A second connection element (7; 7?) is also provided, connected to the second pinch valve (4; 4?) and fitted onto or inserted into the delivery-side end region of the powder chamber (10; 10?).

Abstract: A coating powder feed unit containing a powder pump which in a suction operating mode aspirates coating powder into a powder chamber (30) and in a pressure operating mode expels coating powder by means of compressed air out of the powder chamber (30). Said unit includes a pressure tester (64) measuring the compressed air pressure and generating a test signal based on the measured compressed air pressure.
