  • Publication number: 20140131463
    Abstract: Systems and methods for producing consistent spray patterns and for diminishing clogging experienced when applying spray adhesive from a spray gun are provided. One system includes an automatic non-atomizing spray valve operably coupled to a first and second flow valve. The spray and flow valves are electronically controlled using logic running on a processing unit. The logic is programmed to carry out a spray cycle that involves dispensing a first liquid from the spray valve (first phase) and then dispensing a second liquid through the same spray valve (second phase). Because the first liquid (e.g., water-based adhesive) has the potential to clog a nozzle of the spray valve, a short burst of the second liquid (e.g., cleaning fluid) is introduced to prevent the nozzle from clogging. The spray valve is configured as a pulse width modulated spray gun to further reduce clogging and to generate an evenly distributed spray pattern.

    Abstract: A valve arrangement for spray dampening units on printing machines with a feeder system to supply the valve arrangement with pressurized dampening agent and spray nozzles downstream of the valve arrangement, includes two valves disposed behind each other with staggered opening times. In a first embodiment, the opening times are staggered so that both valves are only open at the same time for a small period of time. This means shorter effective opening times can be achieved than with individual valves. In a second embodiment there is an elastic buffer element between the two valves, and the opening times are completely staggered so that there are no common opening times. When the upstream valve is opened the buffer element generates an additional uptake of dampening agent, which is ejected by the buffer element when the first valve is closed and the downstream valve is opened.

  • Patent number: 6053433
    Abstract: A nozzle mechanism for generating an aerosol-type liquid discharge is provided, which nozzle mechanism ensures one-way movement of liquid during discharge and also has a substantially zero "dead volume" at the tip of the nozzle. The nozzle mechanism includes a flexible nozzle portion with an outlet and a fluid channel, a rigid shaft received within the flexible nozzle portion, and a rigid housing surrounding the flexible nozzle portion and exposing the outlet. The rigid shaft interfaces the outlet to form a first normally-closed, one-way valve, as well as to define a swirling chamber for collecting the liquid which has been channeled from the liquid reservoir, prior to being discharged via the outlet. The outlet has a tubular wall with thickness that decreases along the elongated axis of symmetry for the outlet toward the tip of the outlet. The fluid channel is circumferentially positioned within the flexible nozzle portion to create swirling action of the liquid delivered to said swirling chamber.

  • Patent number: 6016974
    Abstract: The present invention relates to a micropump for the nebulization of fluids with enhanced metering valve. The micropump comprises a hollow body and a set of stem and piston such as to constitute a "metering chamber" in the body. The hollow stem, which exits the body, is joined with a dispensing push-button fitted with a nebulization element. Pressing the dispensing push-button allows the passage of the fluid to be nebulized from the "metering chamber" to an exit duct, comprising the longitudinal cavity of the stem, a "compression pre-chamber" in the dispensing button and passages from the chamber to the nebulization element. The metering valve is obtained by interposing, in said fluid exit duct, an elastically deformable shutter.
