An instrument serves to insert a shuttle into a circuit for circulating a coating product. A chamber for receiving the shuttle, formed in a non-magnetic body is sized for receiving the shuttle in a position where axis of polarization thereof is parallel to a longitudinal axis of the chamber. A mouth connects the chamber to a first end of the body. A control lever equipped with at least two magnets is movable with respect to the chamber between a first position wherein a first magnet is aligned with the longitudinal axis, with a pole oriented towards the chamber having a first polarity, and a second position wherein the second magnet is aligned with the longitudinal axis, with a pole oriented towards the chamber having a second polarity opposite the first polarity.

The disclosure relates to a supply system for supplying multiple consumers with a substance to be applied, preferably paint, for application to motor vehicle bodies and/or add-on parts thereof. The supply system comprises a feed line, a return line, a first consumer device which comprises a first consumer, the first consumer being connected to the feed line and the return line and preferably forming a first consumer of the feed line in the flow direction of the substance to be applied, and a further consumer device which comprises a further consumer, the further consumer being connected to the feed line and the return line and preferably forming a last consumer of the feed line in the flow direction of the substance to be applied and/or being arranged after the first consumer in the flow direction of the substance to be applied. The supply system is distinguished in particular in that the feed line is connected to the return line via a connecting line. The disclosure relates further to an associated coating installation and to an associated supply method.

Apparatus for spraying a fluid, including a pipe, a scraper capable of moving in the pipe, and a casing defining a storage volume for accommodating the scraper in a position for storing the scraper, the scraper being configured to push fluid in front of it which is present in the pipe when the scraper moves in the pipe, the storage volume being in fluid communication with the pipe and being configured to allow the scraper to move between the storage volume and the pipe. The scraper includes a first magnet, and the casing includes a second magnet capable of exerting a first force on the first magnet to move the scraper from the storage volume to the pipe.

The disclosure relates to a supply system for supplying multiple consumers with a substance to be applied, preferably paint, for application to motor vehicle bodies and/or add-on parts thereof. The supply system comprises a feed line, a return line, a first consumer device which comprises a first consumer, the first consumer being connected to the feed line and the return line and preferably forming a first consumer of the feed line in the flow direction of the substance to be applied, and a further consumer device which comprises a further consumer, the further consumer being connected to the feed line and the return line and preferably forming a last consumer of the feed line in the flow direction of the substance to be applied and/or being arranged after the first consumer in the flow direction of the substance to be applied. The supply system is distinguished in particular in that the feed line is connected to the return line via a connecting line. The disclosure relates further to an associated coating installation and to an associated supply method.

A pig for a coating device wherein the coating device has a line system that can be pigged, wherein the pig has an RFID transponder, which is designed to store and/or to transmit and/or to receive data by means of the RFID technology. A coating system for coating an object with a coating material and to a method for controlling a coating system.

A diverter valve can include an inlet; a main line outlet; a flow control outlet; and a bypass member, wherein the bypass member comprises a passage extending through an axis of the bypass member and a plurality of notches. In some embodiments, the diverter valve can provide that the bypass member is configured to be switchable between an open position that allows a flow from the inlet to the main line outlet and a flow control position that allows flow from the inlet to the flow control outlet.

The disclosure relates to a supply system for supplying multiple consumers with a substance to be applied, preferably paint, for application to motor vehicle bodies and/or add-on parts thereof. The supply system comprises a feed line, a return line, a first consumer device which comprises a first consumer, the first consumer being connected to the feed line and the return line and preferably forming a first consumer of the feed line in the flow direction of the substance to be applied, and a further consumer device which comprises a further consumer, the further consumer being connected to the feed line and the return line and preferably forming a last consumer of the feed line in the flow direction of the substance to be applied and/or being arranged after the first consumer in the flow direction of the substance to be applied. The supply system is distinguished in particular in that the feed line is connected to the return line via a connecting line. The disclosure relates further to an associated coating installation and to an associated supply method.

An insulation device for a coating system for coating objects, the coating system having an electrostatically operating application apparatus having a dispensing device which dispenses a coating material, and at least one storage container which is connected to an input valve device via an inlet line and to the dispensing device via a supply line. The insulation device comprises a channel with a physical body which can move in the channel. The physical body has an electrically insulating material and can be moved by means of a fluid pressure between a park position and an insulation position and is designed such that, when it moves from the park position to the insulation position or from the insulation position to the park position, the physical body removes material from an inner casing surface of the channel, so that an electrical insulation path can be formed between the storage container and the input valve device.

A method for conveying a working medium within a supply line (2), wherein a pig package (48) is moved into the supply line (2) by means of a pushing medium conveyed by a first pump (40) to a proximal end of the supply line (2), is intended to enable TPS operation in a manner that is as technically simple as possible. To this end, a first conveying quantity of the pushing medium is determined by means of a first flow-measuring cell (44) associated with the proximal end, wherein a position of the pig package (48) in the supply line (2) is determined from the first conveying quantity and information about the cross-section of the supply line (2).
