The purpose is to provide a discharge system which can minimize wear of a connecting part of a discharging device and a refilling device which is caused under the influence of particulate matters contained in fluid even if connection and disconnection for refilling the discharging device with the fluid is repeated. A discharge system includes a discharging device capable of discharging the fluid, and a refilling device capable of refilling the discharging device with the fluid. The fluid is suppliable from the refilling device side to the discharging device side by inserting one of a discharge-side coupler provided to the discharging device side and a refill-side coupler provided to the refilling device side into the other to connect the discharging device to the refilling device. A clearance size d formed between the discharge-side coupler and the refill-side coupler is determined based on the particle size distribution of the particulate matters that constitutes the fluid.

The disclosure concerns a coating device for coating components with a coating agent, in particular for painting motor vehicle body components with a paint, with a printhead for applying the coating agent to the component, and with a coating agent supply for supplying the printhead with the coating agent to be applied, wherein the coating agent flows from the coating agent supply to the printhead at a specific coating agent pressure and a specific flow rate. The disclosure provides that the coating supply will control the coating agent pressure and/or the flow rate of the coating agent. Furthermore, the disclosure includes an associated operating method.

A fluid pressure-feed device includes a main tank and a sub tank. The sub tank is connected integrally with an upper portion of a main follower plate that applies pressurizing force to a urethane adhesive inside the main tank. A drum pump is provided in an upper portion of a sub follower plate provided in the sub tank. While the urethane adhesive is flowing into the sub tank from the main tank, the urethane adhesive is fed under pressure from the sub tank to a fluid passage by actuation of the drum pump. While the main tank is being replaced, the urethane adhesive inside the sub tank is fed under pressure to the fluid passage by the drum pump.

Provided is an accumulator which can surely discharge a collected fluid material in a first-in first-out manner without causing stagnation of the fluid material. The accumulator includes a housing having a temporarily accumulating space configured to change an inner volume thereof in an axial direction. The housing includes a supply port and a discharge port formed at positions spaced apart from each other in the axial direction and communicating with the temporarily accumulating space. The housing also includes a flow passage for uniformly supplying a fluid material into the temporarily accumulating space through the supply port.

A device for intermittent coating of a substrate moving in a transport direction relative to the device includes a nozzle body comprising two nozzle jaws; an insertion film having a cut-out provided between the two nozzle jaws, wherein the cut-out in the insertion film forms a nozzle slot within the nozzle body, wherein the nozzle slot extends transversely to the transport direction of the substrate and in parallel with the substrate, and wherein the nozzle slot ends in an outlet gap; and a supply channel, wherein the outlet gap is in flow connection with the supply channel via the nozzle slot. A first of the two nozzle jaws is provided with at least two openings which lead into the nozzle slot in series between the supply channel and the outlet gap and which are closed in a fluid-tight manner toward the nozzle slot by at least two elastically deformable elements.

Techniques herein include a bladder-based dispense system using an elongate bladder configured to selectively expand and contract to assist with dispense actions. This dispense system compensates for filter-lag, which often accompanies fluid filtering for microfabrication. This dispense system also provides a high-purity and high precision dispense unit. A process fluid filter is located downstream from a process fluid source as well as a system valve. Downstream from the process fluid filter there are no valves. Dispense actions can be initiated and stop while the system valve is open by using the elongate bladder. The elongate bladder can be expanded to stop or pause a dispense action, and then be contracted to assist with a dispense action.

One embodiment of a container for transferring, storing, and dispensing paint indefinitely for touch-up painting by the use of a plurality of open-ably close-able apertures (310, 320) that cause transferring, storing, and dispensing of paint, in conjunction with a plurality of paint storage areas (1391, 153) that are independently open-ably sealable to allow for various functions such as, sealed storing of paint in one paint storage area while doing touch-up painting from another paint storage area, moving paint from external paint source to a paint storage area, moving paint between paint storage areas. Using standard (180, 190), as well as custom paint applicators allowing for ease of use, and with various features that allow for use with no clean up needed, such as replaceable components (121, 130, 170, 180, 190, 191, 192, 250) non-stick components (121, 130, 141), integral paint tray (130), paint containment features such as paint retaining walls (130) and paint catching recesses (130, 140). Carrying Tray (210) prevents spilling and holds replaceable parts (121, 130, 170, 180, 190, 191, 192, 250) for storage and transport. Other embodiments are described and shown.

Described herein is an apparatus for dynamic metering of sealant volumes, and also described herein is a corresponding method.

The apparatus of the invention includes two containers for sealant components; a first drive, which is connected to two devices, each of which is able to convey one of the sealant components from its container; a drive controller; a mixing unit for mixing the sealant components conveyed from the containers, having an opening for applying the sealant to a component; and also, additionally, a compensating container with a compensating volume; and a second drive, which is connected to a piston which reaches into the compensating volume of the compensating container.

The compensating container in this arrangement is connected to the mixing unit. The first drive and the second drive can be dynamically controlled jointly by the drive controller.

Techniques herein include a bladder-based dispense system using an elongate bladder configured to selectively expand and contract to assist with dispense actions. This dispense system compensates for filter-lag, which often accompanies fluid filtering for microfabrication. This dispense system also provides a high-purity and high precision dispense unit. A meniscus sensor monitors a position of a meniscus of process fluid at a nozzle. The elongate bladder unit is used to maintain a position of the meniscus at a particular location by selectively expanding or contracting the bladder, thereby moving or holding a meniscus position. Expansion of the elongate bladder is also used for a suck-back action after completing a dispense action.

An adhesive dispensing system and method are configured to melt adhesive on demand and maintain the adhesive in a liquid state between dispensing cycles. The dispensing system includes a dispensing applicator with a manifold passage, a receiving device including a receiving chamber for holding a small amount of solid adhesive at the dispensing applicator and a first heating device for melting the adhesive on demand, and a second heating device at the manifold to maintain the temperature of the melted adhesive before dispensing. The second heating device applies heat energy to maintain the adhesive in the manifold passage as a liquid.
