Abstract

A device for dispensing fluid onto a substrate includes a basic body, a fluid supply channel connectible to a fluid source for supplying the fluid, and a nozzle assembly which has a distribution channel that communicates with the fluid supply channel and which has an essentially elongated slit that communicates with the distribution channel. The slit includes at least one discharge opening for dispensing the fluid. The effective length of the distribution channel is variable by means of a closure element that is movable in the distribution channel. An equalization channel is connected with the distribution channel, and the volume of the equalization channel is adjustable.
