When the cleaning fluid is positively supplied directly to the discharge flow path of the coating solution discharge nozzle, the supply pressure of the cleaning fluid as well as the capability of cleaning is added. Therefore, further effective cleaning is attained in compare with the conventional case where a coating solution discharge nozzle is simply dipped into a cleaning fluid. In consequence, even when the discharging port of the nozzle is minute, it is possible to perfectly remove the contamination. This allows the discharge pressure to remain constant so as to form a uniform coating layer on the substrate.

  • Patent number: 5813608
    Abstract: A multi-color rotary spraygun has a bell-shaped head which is supported for rotation on a front end of a casing. The front end portion of the bell-shaped head is covered with a partition wall having coating material spraying ports. A plurality of coating material lines open into the bell-shaped head at their front ends and are respectively connected to separate coating material sources at their base ends. A coating material supplied to the bell-shaped head from one of the coating material sources through one of the coating material lines is atomized and sprayed on an object through the spraying ports by rotation of the bell-shaped head. The front end portion of a cleaner line which is connected to a cleaner source at its base end is disposed in the bell-shaped head and the front end portion of the coating material lines are disposed around the front end portion of the cleaner line.

  • Patent number: 5435488
    Abstract: An improved method and apparatus for discharging a liquid material which includes volatile components comprises a gun body for discharging the liquid from a nozzle orifice at a nozzle end thereof, and a hood mounted to the nozzle end, the hood defining an open inner space around the nozzle hole. The open space provided by the hood maintains the nozzle end in a state of relatively stable conditions to reduce viscosity changes and/or hardening of the liquid on the nozzle end, particularly during intermittent discharge operations. A water permeable liner may be located in the hood to actively humidify the discharged liquid as it traverses the open space. A cleaning nozzle may be aimed at the nozzle end of the gun body to direct a cleaning agent thereagainst, the cleaning agent being removed from the open space via an exhaust outlet aligned with the cleaning nozzle. One or more additional hoods may be used to provide further stages of protection.

  • Patent number: 5429303
    Abstract: A steam spray tube with an inlet line (16) for steam, a nozzle arrangement (33) and a valve (19) positioned between the inlet line and the nozzle arrangement is described. With such a steam spray tube, adequate moistening of a web to be moistened can be assured even at high web velocities. To do so, an essentially straight acceleration channel (35) is arranged downstream from valve (19) in the direction of flow of the steam and a nozzle channel (36) to the nozzle arrangement (33) branches off from the acceleration channel at a predetermined distance from the end (37) of the acceleration channel (35).

  • Patent number: 5411210
    Abstract: A device for atomizing and dispensing a first liquid coating material onto a first group of one or more articles to be coated by the first coating material and then for dispensing a second liquid coating material onto a second group of one or more articles to be coated by the second coating material. The device includes at least one atomizer providing a first flow rate of the first and second coating materials required for high quality atomization of the first and second coating materials, and a second outlet providing a second and substantially greater flow rate of the first and second coating materials and lower quality atomization than the first atomizer, or no atomization. A first conduit couples the second outlet to the first atomizer. A second conduit couples the first atomizer to a source of fluid to be dispensed. A valve controls the flow of liquid to the second outlet.

  • Patent number: 5211335
    Abstract: A spray tube nozzle adapted to be cleaned during its operation. The nozzle includes a nozzle head having an inlet connectable to a conduit and an outlet for spraying liquid. Within the nozzle head is located a rotatable element defining a through-hole. The through-hole is shaped in such a way that the opening at one end is of relatively small cross-section and at the opposite end of a relatively large cross-section. The rotatable element is sealingly arranged in the nozzle head and has an external groove. The rotatable element can be positioned in at least a first rotational position to facilitate flow of spraying liquid from the conduit, to the nozzle inlet, and through the through-hole in the rotatable element, to the nozzle outlet for forming spray jets at the outlet. A second rotational position allows liquid to be flushed through the conduit by flow of the spraying liquid from the inlet, through the groove, and exiting the nozzle through a flush hole.

    Abstract: A liquid mixing and dispensing nozzle for a beverage which is to combine a concentrate (syrup) with a non-viscous liquid in a manner to increase the amount of carbonation leaving the soda yet achieving even mixing of the soda and the syrup. These advantages are obtained at a high flow rate, such as approximately six ounces per second of the beverage. The nozzle discharges the soda in an annular pattern with the syrup being discharged centrally within this pattern.

  • Patent number: 4745011
    Abstract: A two-component mixing type coating method which is utilized for coating car components, and the like. A main component solution and a hardner solution are run together at an intermediate portion of a supply conduit and are mixed. The mixture solution is sent to a coating spray gun and injected from the gun for coating. The two-component mixing type coating method of the present invention is characterized in that check valves and stop valves are disposed at positions of the flow conduits upstream from the junction, an escape valve is connected to a flow conduit at a portion downstream from the junction, and when the coating spray operation from the coating spray gun is stopped, the escape valve is opened and then the stop valves are closed by control means.

  • Patent number: 4735361
    Abstract: A fluid dispersing apparatus suitable for use as a sprinkler in water irrigation applications whereby a jet of fluid is reflected from one or more rigid surfaces to preserve fluid particle speed. The reflecting surfaces are shaped to provide a variable but adjustable range of sector coverage in the spray pattern while maintaining range of fluid dispersal coverage. Through substitution of system components, a broad range of fluid dispersing requirements can be met with the same basic substructure. In the absence of fluid jet pressure, the principal jet reflecting assembly settles into a compact, low profile configuration.
