Abstract:
1. A device for dispensing fluid onto a substrate, comprising: a basic body; a fluid supply channel in said basic body adapted to communicate with a source of the fluid; a nozzle assembly including a distribution channel that communicates with said fluid supply channel; a slit including a discharge opening communicating with said distribution channel; a closure element mounted for movement along said distribution channel, wherein moving said closure element within said distribution channel defines a variable distribution volume within said distribution channel; an equalization channel in said nozzle assembly and communicating with said distribution channel; and a displacement element mounted for movement along said equalization channel, wherein moving said displacement element within said equalization channel defines a variable equalization the volume within said equalization channel, wherein increasing one of said equalization and distribution volumes simultaneously decreases the other of said distribution and equalization volumes such that said equalization volume and said distribution volume define a constant volume within said nozzle assembly.
