Device for elevating liquids with a plurality of intermediate containers communicating with one another

A device for elevating liquids, comprising

• a heat exchanging vessel arranged to be heated by a source of heat and to receive a liquid which is vaporized and produces a high pressure vapor and after vaporization produces a suction;
• an auxiliary vessel accommodating a liquid and connected with said heat exchanging vessel to supply a liquid into the latter to be heated and vaporized;
• an inlet pipe connected with a source of a liquid;
• and
• a discharge pipe arranged to elevate doses of liquid and connected with said inlet pipe to receive the liquid from said inlet pipe, said discharge pipe being also connected with said heat exchanging vessel so that for performing a thermodynamic cycle the liquid to be elevated is used as a working medium in that the high pressure vapor produced in said heat exchanging vessel forces the liquid in said discharge pipe up and after the vaporization of the liquid the produced suction draws the liquid from said inlet pipe into said discharge pipe,
• said discharge pipe having a plurality of vertically spaced containers, a plurality of pairs of pipe portions each pair connecting two neighboring ones of said containers, and an emptying member located in each container and associated with one pipe portion of each of said pairs of pipe portions,
• one portion of each of said pairs of pipe portions having a lower end associated with said emptying member, said emptying member having a predetermined height, said one pipe portion of each of said pairs of pipe portions having a bubbling chamber located above said emptying member, said bubbling chamber having a height which is smaller and a volume which is greater than that of said emptying member.
