Abstract
An apparatus or dosing of liquids into a gas filled space comprising: a pump; a dosing orifice for introduction of liquid into the gas filled space; a discharge line, which connects a pressure side of the pump with the dosing orifice; and an elastic, liquid storer. The discharge line includes a shutoff valve between the pump and the dosing orifice, wherein the elastic, liquid storer is located between the pump and the shutoff valve, and the apparatus includes a first operating state, in which the pump runs in the case of closed shutoff valve, in order to store in the elastic, liquid storer a liquid amount under pressure.

An apparatus for dosing of liquids into a gas filled space, comprising:
- a pump;
- a dosing orifice for introduction of liquid into a gas filled space;
- a discharge line, which connects a pressure side of said pump with said dosing orifice;
- and
- an elastic, liquid storer;
- wherein:
- said discharge line includes a shutoff valve between said pump and said dosing orifice;
- said elastic, liquid storer is located between said pump and said shutoff valve;
- and a first operating state, in which said pump runs in the case of a closed shutoff valve, in order to store in said elastic, liquid storer a liquid amount under pressure.
A method for dosing liquids into a gas filled space, comprising the steps of:
- operating a pump, in order to supply a defined liquid amount via a discharge line into an elastic, liquid storer, which, upon attaining the defined liquid amount, has a defined positive pressure, wherein the discharge line is closed relative to a dosing orifice by means of a shutoff valve, and wherein the elastic, liquid storer is located between the pump and the shutoff valve;
- and
- opening the shutoff valve in the case of a turned-off pump, in order that the liquid storer expels the defined liquid amount, wherein the stored liquid based on the positive pressure in the elastic, liquid storer, escapes from the elastic, liquid storer with such a velocity, that a corresponding amount of liquid, which escapes from the dosing orifice, based on its velocity, overcomes adhesive forces to the dosing orifice and separates from the dosing orifice.
