The nozzle system is ideally suited for use within a high-pressure chemical spray system. The preferred nozzles are impingement nozzles, where the chemical discharge leaves an orifice, and then collides with a distributor. The distributor breaks the stream of chemical into droplets, which then mix with the surrounding air.

Stock nozzles are altered by: removing a paper filter from each of the one or more nozzles; removing a metal mesh screen from the one or more nozzles; installing a polypropylene filter with a pore size lesser than the orifice size; and installing the one or more nozzles into the nozzle array.

A spray structure for a portable atomizer includes: a case including an opening; a cover exposed through the opening of the case; a head portion placed in the case and coupled to the cover, the head portion including a discharge hole; and an elastic portion between the head portion and the cover, wherein the cover is configured to be rotated on a first axis by a first angle above the head portion to expose the discharge hole through the opening of the case and to be linearly moved in a second direction perpendicular to the first axis in a state in which the discharge hole is exposed.

According to the present invention, there is provided a foaming apparatus that discharges a foamable material obtained by mixing gas into a viscous material of a resin and dispersing bubbles in a liquid of the viscous material. The foaming apparatus includes: a pipe; a material supply unit; a gas supply unit; a first gear pump; a second gear pump; a third gear pump; a mixer; a discharge unit; and a control unit.

A state determination device determines a state of a paint device including an air motor that rotates by a supply of a gas, a rotational shaft that serves as a rotational center of the air motor, and a rotary atomizer head that is connected to the rotational shaft and sprays paint. The paint device further includes a vibration detection unit that detects a vibration of the paint device, and the state determination device includes a frequency component acquisition unit and an abnormality determination unit. The frequency component acquisition unit acquires a frequency component caused by a contact between the rotational shaft and the air motor from a detection result by the vibration detection unit. The abnormality determination unit determines whether an abnormality of the air motor exists or not based on an acquisition result by the frequency component acquisition unit.

A dispensing system for dispensing a hot melt adhesive foam onto a substrate is described. The dispensing system comprises a pump having a first input to receive a hot melt adhesive and a second input to receive a gas, where the pump mixes the hot melt adhesive and the gas to produce a solution. The dispensing system also includes a temperature sensor to detect a temperature of the solution, a dispenser to receive the solution from the pump and dispense the solution, and a controller. The controller instructs the pump to operate at a first speed, receives the temperature of the solution, and instructs the pump to operate at a second speed that is different than the first speed in response to the signal.

The preset disclosure relates to a dishwasher. The dishwasher includes: a tub defining a washing space; a sump disposed below the tub and configured to store wash water therein; a pump configured to supply the wash water stored in the sump to the tub; and a spray arm configured to supply wash water flowing from the pump to the washing space. The spray arm includes: a spray blade configured to spray wash water into the washing space; a bubble generator having therein a bubble generation flow path of a venturi tube shape and configured to supply wash water containing a microbubble to the washing space; and a hub configured to supply wash water discharged from the pump to the spray blade or the bubble generator. The spray arm sprays wash water through the spray blade while simultaneously generating a microbubble through the bubble generator.

A fluid application system includes: an application apparatus that discharges a fluid to a workpiece; a movement apparatus that moves the application apparatus and the workpiece; and a control apparatus. At the time of adjusting the output of a power source to thereby vary the discharge amount of the fluid from the nozzle by a target variation amount F1, the control apparatus sets the output of the power source to a value beyond a theoretical output N1 of the power source obtained from the target variation amount F1 of the discharge amount, and then sets the output of the power source to the theoretical output N1 such that the change amount of the internal pressure of the nozzle is coincident with an amount P1 by which the internal pressure of the nozzle needs to change, the amount P1 being obtained from the target variation amount F1 of the discharge amount.

The invention relates to a method for dispensing viscous or pasty ingredients (12), which are packaged in an aseptic manner, from a tubular bag (1), which is closed prior to the first use, by means of a disposable pump (4) attached to the bag. The disposable pump (4) has an inlet (5) with a cutting element (6), and a nozzle (2) with a flange (3) is welded onto the tubular bag (1). The disposable pump (4) is rotated relative to the nozzle (2), and the tubular bag (1) is thereby cut open. A valve (9) is arranged in the region of the outlet opening of an outlet tube (8) of the pump, and the disposable pump (4) is operated after the initial opening process until a freely selectable volume has exited the closing valve. The disposable pump (4) is then operated in the opposite rotational direction in order to suction ingredients (12) present on or in the region of the valve (9) back into the outlet tube (8). In the process, the valve (9) reaches or remains in the closed valve state. A valve (9) is proposed for carrying out the method. The valve is arranged in the outlet tube (8) and comprises a membrane (93, 191) which is sealingly mounted in a sliding manner or can be inverted. Using the method, the ingredients (12) can be dispensed in a metered manner from a tubular bag (1), in which the ingredients are aseptically packaged, into virtually aseptic containers until the ingredients are practically completely used.
