Abstract
Abstract This invention relates to an apparatus in which a viscous substance, taken automatically from a tank, is expelled outside the tank in doses whose volume can be made adjustable as a function of the need. The dose is obtained by the action of a vertical thrust from the bottom to the top upon a distributing member, placing pressure on the substance in a container with a variable volume and expelling it through an opening formed through an elastic member. This invention applies to the distribution of doses of liquid substances having various viscosities.
