Summary for Patent: 5,405,084
Title: Nozzle assembly for preventing back-flow
Abstract:A nozzle assembly which comprises a nozzle aperture for discharge of a fluid as a spray of droplets, and a conduit in fluid flow communication with the nozzle aperture. The flow of fluid through the conduit is restricted by the minimum effective cross-sectional area of the conduit transverse to the line of flow of fluid through the conduit so that back flow of fluid from the nozzle aperture through the conduit at ambient and operational pressure differentials is substantially prevented. The invention further provides for a method of discharging a fluid as a spray of droplets, and a spray generating device which includes the nozzle assembly of the present invention.
