Abstract
A nozzle assembly for a liquid dispenser includes an outlet member that defines a liquid supply conduit and a nozzle that includes an exit orifice, wherein the nozzle is disposed over an end of the outlet member. A liquid compression path is defined by the nozzle and the outlet member, wherein the liquid compression path includes a liquid compression chamber that supplies liquid from the liquid supply conduit to the exit orifice. The nozzle is adjustable between a first spray position for projecting a liquid spray having a first average droplet size and a second spray position for projecting a liquid spray having a first average droplet size. In the first spray position the liquid compression chamber has a first volume and in the second spray position the liquid compression chamber has a second volume. Preferably, the liquid spray is formed without a swirl chamber.
