Distribution for forming a thin liquid layer on a surface

摘要

A device for distributing a liquid in the form of a thin layer on a surface is housed in a cylinder and is provided with a freely displaceable spring-loaded piston for ejecting and distributing liquid from a chamber formed by the piston and a base plate member having a plurality of bores. The base plate member bores are opened and closed by nozzle needles which extend through bores disposed in the displaceable piston to a support plate to which the needles are affixed and which is adapted for moving the needles towards and away from the base plate member bores for closing and opening the base plate member bores for regulating distribution of the liquid.
