Abstract
A fluid dispensing apparatus includes a dispenser body, a valve stem with a valve tip, and a nozzle having a nozzle body defining a fluid chamber terminating in a discharge outlet, an annular valve seat, and a resilient annular portion. A method for dispensing droplets of fluid with the fluid dispensing apparatus includes moving the valve stem relative to the dispenser body and the nozzle body, collecting fluid in the fluid chamber flowing from the dispenser body when the valve stem is moved in an upstream direction with the valve tip out of engagement with the annular valve seat and the resilient annular portion, and dispensing fluid in the fluid chamber out of the discharge outlet when the valve stem is moved in a downstream direction.
