A pump arrangement, in particular in a coating installation for the coating of components, such as a painting installation for the painting of motor vehicle body components, is provided. The pump arrangement includes a plurality of adjustable pumps for delivering a coating agent, e.g. for delivering a sealing agent for the sealing of weld seams on a motor vehicle body component. The pumps are connected in parallel such that the pumps extract the coating agent for delivery from a common inlet line and deliver said coating agent into a common outlet line. The arrangement further includes a control device for the open-loop or closed-loop control of one fluid variable at the outlet of the individual pumps, respectively, wherein the control device actuates the individual pumps individually, and/or a monitoring unit, which switches the pumps on and off non-simultaneously.

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 valve on the inlet side is connected to the compressed air source by a fluid-conducting rotary feedthrough and on the exhaust air side is connected to the compressed air controlled valves of the spray units.

The present invention relates to a perfume dispensing device, the device being electronically controlled and the actuation of perfume spraying being performed via an actuator (12) located on or under a device housing (1). All components of the device are located on or in the housing (1), wherein the housing also accommodates a control circuit (10) for controlling the device, which may optionally include a system (13) for wireless communication with a smart device (14) having a dedicated application uploaded, through which the user sets the desired parameters. The device may include several storage containers (2), which allows the user to select the desired perfume or to personalise the perfume via a dedicated application. The actuator is actuated by pressing or touching the actuator (12) or via an external device.

Provided is a wet atomizer for processing all-solid-state battery raw materials while ensuring sealing property, operability after completion of processing, and maintenance property. The wet atomizer includes a liquid supply pump for supplying the all-solid-state battery raw materials, a pressure intensifier for pressurizing the all-solid-state battery raw materials supplied from the liquid supply pump, a high-pressure filter for filtering the all-solid-state battery raw materials pressurized by the pressure intensifier, a chamber for injecting the all-solid-state battery raw materials filtered by the high-pressure filter, a sealing member for sealing the space for processing the all-solid-state battery raw materials, and an inert gas supply unit for supplying an inert gas to the sealing member.

In some implementations, a controller may receive an input that indicates a proportion of a spray cycle in which a fluid spray system is to be active. The fluid spray system may include at least a first fluid pump configured to supply fluid to a first fluid spray bar and a second fluid pump configured to supply fluid to a second fluid spray bar. The controller may determine, in accordance with the proportion, a spraying timing for the first fluid pump and the second fluid pump that minimizes an overlap of an active time of the first fluid pump and an active time of the second fluid pump, and/or an overlap of an inactive time of the first fluid pump and an inactive time of the second fluid pump. The controller may cause activation of the first fluid pump and the second fluid pump in accordance with the spraying timing.

A process for the production of spunbonded nonwoven (1) is shown, wherein a spinning mass (2) is extruded through a plurality of nozzle holes (4) of at least one spinneret (3, 40, 50) to form filaments (5) and the filaments (5) are drawn, in each case, in the extrusion direction, wherein the filaments (5) are deposited on a perforated conveying device (10) to form a spunbonded nonwoven (1) and wherein the nozzle holes (4) of the spinneret (3, 40, 50) are arranged along a main axis (6) oriented in a transverse direction (12) to the conveying direction (11) of the conveying device (10) so that the spunbonded nonwoven (1) formed on the conveying device (10) extends in this transverse direction (12). So as to enable the spinning width and the basis weight distribution of the spunbonded nonwoven to be adjusted reliably and, respectively, to allow the basis weight distribution to be kept constant during operation by means of the process, it is suggested that the spinning mass throughput (31) of the nozzle holes (4) is adjusted variably along the transverse direction (12).

A liquid delivery device includes a cylinder having a liquid retention section configured to retain a liquid, a piston configured to change a volume of the liquid retention section, a gas container configured to encapsulate a gas at pressure exceeding atmospheric pressure, a regulator which is coupled to the gas container, and is configured to adjust pressure of the gas delivered from the gas container, a gas flow channel having a supply flow channel configured to supply the gas delivered from the regulator to the piston, and a release-to-atmosphere flow channel configured to release the gas delivered from the regulator to an atmosphere, and a three-way valve provided to the gas flow channel to switch between delivering the gas delivered from the regulator to the supply flow channel and delivering the gas to the release-to-atmosphere flow channel.
