Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side.

The invention relates to a method for providing a spray gun (1) in a washing space (2) in a spray gun washing device (3), said spray gun comprising a paint passage (7) with a paint inlet (8). The washing space (2) comprises at least one cleaning nozzle (4) and an attachment surface (10). The cleaning nozzle (4) communicates with a cleaning medium system (5). The attachment surface (10) in the washing space (2) is configured to receive a spray gun (1) with a spray gun holder (9) since the position of the spray gun in the washing space is variable depending on the position of a paint inlet (8) of the spray gun relative to the position of the cleaning nozzle (4) in the washing space. The invention also relates to a spray gun washing device (3) comprising said characterizing features for cleaning the spray gun (1) which during cleaning is provided in said spray gun holder (9).

A dispenser machine includes a dispenser device with a valve assembly. The valve assembly includes at least one distribution duct, at least one distribution nozzle connected to a second end of the distribution duct, at least one first shutter, and at least one valve body, operationally interposed along the distribution duct. The valve assembly includes a closing device for closing the nozzle. The closing device has at least one obstructing element acting upon an aperture of the nozzle for selectively opening or closing the nozzle, and a mechanical connector for connecting the obstructing element to the first shutter, so that switching the shutter will cause the obstructing element to be switched. The shutter is adapted to translate within the valve body between first and second configurations, causing the corresponding obstructing element to switch, respectively, between the closed condition and the open condition.

A dispensing method is disclosed that includes the following steps: a cleaning sleeve is provided to surround a spray member. A first fluid is previously dispensed from a first fluid outlet of the spray member. A second fluid is sprayed from a second fluid outlet of the cleaning sleeve to clean the spray member. The cleaning sleeve is opened or slid away from the spray member, such that the first fluid outlet of the spray member is exposed to a substrate. The first fluid is dispensed from the first fluid outlet of the spray member to the substrate.

A coating system for coating objects having an application device and a supply system which supplies the application device with a liquid material. The supply system includes at least one base supply device with a piggable supply line which extends between a first pigging station and a second pigging station and can be connected to one of multiple material sources by a supply unit. The piggable supply line is a piggable primary supply line which can be connected to a discharge line of the supply unit by a valve unit. A piggable secondary supply line is provided which is connected to the valve unit and is connected to a secondary pigging station at the end remote from the valve unit. The valve unit is designed as a multi-way valve such that the discharge line of the supply unit can be at least selectively connected to the primary supply line (68.1); or the discharge line of the supply unit can be at least selectively connected to the primary supply line and the secondary supply line; or the primary supply line can be at least selectively connected to the secondary supply line.

The invention relates to a shower arm with a torus regulator and a magnetic ring that is comprised of a body (1) with a body head (25), a bell (2), a cover (3), a torus (4), a mixing element (5), a ring (6), a pin (7) and a barrier (9) on the cover, a barrier (8) and a nozzle (10) on the bell, a cavity (11) for water inlet, an inlet (12) of water into the shower head (25), a space (13), a gap (14) on the mixing element, a chamber (15), gaskets (16) and (17), a thread (18), a space (19) for directed flow, pins (20) and a groove (21) on the ring, a groove (22) on the bell, a thread (23) for connecting a hose, a support surface (24) a magnetic ring (26) and an output spray (27) of water and air. When the water circulates within the space (19) underneath the torus (4), negative pressure—vacuum occurs from both the internal and the external sides of the torus cross-section that conditions suction of the air from the chamber (15) of the cone of the bell (2). This air is suctioned through the nozzle (10). In the space below the mixing element (5) the air and the water swirl which alternately enter into the air/water mixture and form a wide conical spray (27). The bell is provided with the groove (22), into which the ring (6) with pins (20) is tightly inserted. The pins are made from a soft material and serve for mechanical massage of the skin and the crown of the hair. On the other side in the ring there is the groove (21), into which the magnetic ring (26) is inserted. Its role is to normalize the water crystals and to arrange them into a natural shape. The nozzle (10) for spray outlet has an orifice large enough in order not to clog due to impurities in the water and limescale.

A manufacturing method of a liquid ejection head, which includes a step of preparing a substrate including a first layer, a step of forming a flow path mold for forming the flow path and a member located outside the mold with a gap between the mold and the member from the first layer, a step of providing a second layer so that the second layer fills the gap and covers the mold and the member located outside the mold with the gap between them, a step of forming an ejection orifice forming member for forming an ejection orifice from the second layer, a step of removing the member located outside the mold with the gap between them, and a step of forming a wall member located outside the ejection orifice forming member with at least a partial gap between the ejection orifice forming member and the wall member.

A spray dryer absorber operative for removing gaseous pollutants from a hot process flue gas and a vibrator device for removing accumulated deposits therefrom is provided. The spray dryer absorber includes a spray dryer chamber equipped with a plurality of dispersers and atomizers mounted at a roof of the spray dryer chamber. The vibrator device is operative to remove accumulated deposits from the spray dryer absorber and its components, such as its dispersers and atomizers, to avoid spray dryer absorber performance interference caused by such deposit accumulations.

A nozzle cleaning device and a method of using the same are disclosed. The nozzle cleaning device has a cavity and a sealed chamber formed therein. The sealed chamber is provided with a cleaning tank, motors, driving bearings connected to the motors, rotation shafts connected to the driving bearings, a cleaning block fitted on the rotation shafts disposed above carrier portions, a heating means, and an ultrasonic wave device, so as to thoroughly clean nozzle portions which the mechanical procedure cannot clean, achieving a better cleaning effect, and being easier to use.

The disclosure relates to a painting system component, in particular a rotating bell (1) for a rotating atomizer, including a main body (1) and a surface coat (8) at least on a part of the surface of the main body (1). The surface coat (8) reduces the tendency of the painting system component to become dirty and/or improves the ease of cleaning of the painting system component.
