An atomizing spray device includes a housing having inlets that receive a first fluid and a slurry of ceramic particles and a second fluid. The inlets are fluidly coupled with outlets by an interior chamber that mixes the first fluid with the slurry to form a primary mixture of the first fluid and first atomized droplets of the slurry. A first outlet on a first side of the housing and a second outlet on the first side of the housing are shaped to change the primary mixture to form a secondary mixture of the first fluid and second atomized droplets of the slurry. The first outlet sprays the secondary mixture onto a first surface as a first layer of coating and the second outlet sprays the secondary mixture onto the first surface as a second layer of coating while the housing moves in a direction along the first surface.

A spray device includes a first spray tip having a first fluid pathway defining a first flow area, and a second spray tip includes a second fluid pathway that defines a second flow area that is larger than the first flow area of the first spray tip. The first and second spray tips are side-by-side and spaced from one another at a distal end of the spray device. When a first fluid having a volumetric flow rate is introduced into the first spray tip and a second fluid having the same volumetric flow rate is introduced into the second spray tip, the first fluid will flow through the first fluid pathway at a greater velocity than the second fluid will flow through the second fluid pathway.

A liquid dispensing apparatus has a frame, a plurality of tubes supported by the frame, and a roller assembly supported by the frame. The roller assembly is movable between an upper position and a lower position. The roller assembly is cooperative with the plurality of tubes so as to apply compressive force to the plurality of tubes in the upper position and to release the compressive force in the lower position. The roller assembly is movable for a desired distance along the length of the plurality of tubes. The roller assembly is adapted to urge a liquid out of a lower end of the plurality of tubes by applying the compressive force to the plurality of tubes and moving the roller assembly downwardly along the plurality of tubes while the compressive force is applied to the plurality of tubes.

A spray head for supplying at least one die of a forming machine with lubricating coolant, the forming machine including a lower die and an upper die, is preferably produced by rapid manufacturing and is designed as a single piece to a large extent. The use of rapid manufacturing allows the production of the most varied configurations, such as stabilizing honey-comb structures or drip points, which allow a more advantageous design of the spray head. The spray head carries at least one two-substance nozzle connected with at least one feed channel. The nozzle body of the nozzle and the channel wall of the feed channel are configured in one piece with one another or the channel wall of the feed channel and a spray head foot carrying a supply connector connected with the feed channel are configured in one piece with one another.

A method for spraying a mixture comprising at least a first liquid in the form of a liquid preparation of water-soluble or water-swellable polymers and at least a second liquid, characterized in that it implements a nozzle for simultaneously spraying at least two liquids, comprising: a body provided with a first chamber within which a first liquid flows and a second chamber within which a second liquid flows, each of the two chambers having a through-hole on the outside of the body, a deflector secured to the body arranged downstream from at least one of the through-holes, in the direction of flow of the first and second liquids, said deflector being capable of modifying the direction of flow of the first and second liquids. The invention also relates to a nozzle for implementing the method.

The heterogeneous contents mixing container includes a first container formed therein with a content storage space and a container coupling space separated from each other; a second container coupled to the first container and formed with an inlet and a coupling portion; a first discharge unit installed in the first container to discharge stored contents; a second discharge unit installed in the second container to discharge stored contents; and a push button configured to operate the first and second discharge units and formed with first and second discharge passages and first and second outlets which are connected to the first and second discharge units, respectively, wherein the container coupling space of the first container and the inlet and the coupling portion of the second container deviate to one side from a center between the first and second containers, and the second discharge is connected to the second discharge passage.

A generator of air/oil mist includes an accumulation chamber for a mist of particles of oil in air, and equipped with a first mist outlet and a nebulizer feeding into the accumulation chamber, the nebulizer including a first nozzle supplied with pressurised air, which features at least a first channel supplied with the pressurised air, each channel being equipped with an outlet on a surface of the first nozzle partially defining a first chamber axially symmetrical with respect to an axis, the channels being positioned to generate a rotation of the air fed into the first chamber around the said axis, the surface of the first nozzle featuring a section converging towards an outlet hole, the nebulizer featuring a second nozzle supplied with oil and feeding out into the first chamber so that the oil is suctioned via the second nozzle because of the air flowing through the first chamber.

An air/oil mist generator (1A) including an accumulation chamber (2) inside which a mist of oil particles in air accumulates, the accumulation chamber (2) being provided with at least a first mist outlet (4), the generator (1A) comprising a nebulizer (3, 3A) feeding into the said accumulation chamber (2), the nebulizer (3) being optimised to operate at a first pressure level and being fed by a first line (BA) of compressed air at the said first pressure level, the generator (1A) further including a further nebulizer (3A) which also feeds into the accumulation chamber (2) optimised to operate at a second pressure level which is higher than the first pressure level, the further nebulizer being fed by a second line (AL) of compressed air at the second pressure level; the first line (BA) being optionally associated with a non-return valve (807) which prevents a backflow coming from the accumulation chamber (2).

An air/oil mist generator (1, 1A), comprising an accumulation chamber (2) inside which a mist of oil particles in air accumulates, the accumulation chamber (2) being provided with at least one first mist outlet (4), at least one nebulizer (3, 3A) feeding into the said accumulation chamber (2), wherein the accumulation chamber (2) is associated with a differential pressure regulator (12), which feeds the compressed air into the accumulation chamber when the difference between the internal pressure of the accumulation chamber (2) and the nebulizer supply pressure (3) exceeds a predefined threshold value.

A binary nozzle for atomizing a mixture of agent to be sprayed and spray air is connected to at least one supply duct via which the mixture or the agent to be sprayed can be supplied to the binary nozzle, wherein a valve is arranged between this supply duct and a nozzle outlet of the binary nozzle. A corresponding spray head and also a method for atomizing a mixture of agent to be sprayed and spray air uses a binary nozzle. The binary nozzle includes a nozzle body formed in a single piece and including the nozzle outlet, wherein a movable assembly of the valve is fastened to the nozzle body by a fastening element and/or held tight against the nozzle body by a spring device.
