摘要： A spray nozzle assembly for producing an oscillating spray discharge is provided. The spray nozzle assembly includes a nozzle body with a liquid inlet passage that converges via an inwardly converging conical section that defines a liquid inlet orifice. An expansion chamber communicates in a downstream direction with the liquid inlet orifice. An exit orifice communicates in the downstream direction with the expansion chamber. A pair of longitudinal veins and a pair of outwardly disposed feedback passages are provided in the expansion chamber. Each vein defines a respective downstream orifice to a respective one of the feedback passages adjacent the exit orifice and an upstream orifice to the respective one of the feedback passages adjacent the inlet orifice.

摘要： A modular liquid distribution system in which each module has a module body, a spray nozzle, and a piston for controlling the dispensing of liquid from the nozzle. Each module has a pneumatically operated system for moving the piston to an open position while facilitating quicker return movement to a closed position, enabling the dispensing of precisely controlled small droplet sized quantities of highly viscous liquids.

摘要： A modular liquid distribution system in which each module has a module body, a spray nozzle, and a cyclically operable piston for controlling the dispensing of high viscous liquids from the spray nozzle. Each spray nozzle has a nozzle body with a liquid inlet and a tear dropped shaped pintle which together with the nozzle body defines an expansion chamber that reduces velocity of the liquid sufficient to be dispensed in small droplet form without splattering. In one embodiment, the nozzle body has a discharge orifice sized smaller than the outer diameter of the expansion chamber for accelerating liquid flow upon discharge sufficient to enhance consistent and repeatable breaks in the cyclically controlled fluid flow stream for enabling the discharge of smaller and more consistent volumes.
