Abstract:
A device for distribution of dosed quantities of a liquid comprising:a storage container;a conduit connected to said storage container;a nozzle connected to said conduit;a receiving container positioned so as to receive a discharge of the liquid from said nozzle;a gauge means connected to said receiving component, said gauge means for delivering a signal representative of a quantity of liquid in said receiving container;a valve means interactive with said conduit for blocking or opening the passage of the liquid through said conduit from said storage container to said nozzle, said nozzle having a diameter such that the liquid in said conduit is immobilized by surface tension forces when said valve means blocks the passage of the liquid, said conduit having an upstream section connected to said storage container and a downstream section having an open end from which said nozzle is formed, said valve means being a slide valve which is normally in a position blocking the passage of the liquid, said upstream section connected to one side of said slide valve, said downstream section connected to another side of said slide valve, said slide valve comprising a valve body in which a housing is formed, said housing having an upstream part and a downstream part communicating with each other via an intermediate section, said intermediate section having a cylindrical form, said slide valve further comprising a valve seat formed in said intermediate section at an opening thereof at said upstream part, a valve member being mobile within said upstream part, said valve resting against said valve seat when said valve means is in the blocking position, said valve body having a first drill hole formed therein such that said upstream part of said housing is connected to said upstream section of said conduit, said valve body having a second drill hole connecting said intermediate section of said housing to said downstream section of said conduit, said valve body having a third drill hole extending along an axis perpendicular to said valve seat and opening into said downstream part of said housing, said third drill hole having a shaft extending therethrough operatively connected to said valve, said shaft being connected to an operating mechanism, said valve being connected to an impulse mechanism.
