Abstract

The invention can be used for pumping fluids. The purpose of the invention is to expand the functionality of the device by expanding the range of possible changes in the average absolute mp of the working fluid. A variable volume tank 3 is placed in a freely floating state in the vertical working chamber 2. As a result of heating the working fluid, the tank 3 floats up, and when the working fluid is cooled, it sinks. Due to the periodic change in pressure in the pumped medium, it is sucked and injected to the consumer. The container 3 is placed in a working environment, which is separated from the pumped medium. Capacity 3 is fixed at the time of heating in the lower and upper position. The average pressure in a heat-conducting medium is regulated in proportion to the change in its mean absolute t-re. In the housing 1, permanent magnets 17, 18 are installed at the upper and lower ends of the chamber 2. The upper and lower walls of the container 3 are equipped with elements 19, 20 made of a paramagnetic material. Elements 19, 20 are made in the form of loads of different weights. The mass of the load 19 is less than the mass of the load 20. The loads 19, 20 are thermally insulated. 4 hp ff. 4 il.

The container 3 is placed in a heat-conducting medium consisting of components A and 5. The latter are separated by a diaphragm 10 from the pumped medium. The container 3 is heated by component 5 obtained from the heat of an external source or heat is taken from the pumped medium (Fig. 3) When heating and expanding the working fluid in capacity 3, it expands and acquires positive buoyancy, but until some time is held by the magnet 18 in the lower position, at a certain moment the buoyancy force overcomes the force of the magnet 18, and the capacitance 3 stroke through separator 14 A method of lifting liquid by periodically heating and cooling the working fluid in a tank of variable volume, placed in a freely floating state in the vertical working chamber, is imparted due to the heating of the working fluid to the positive buoyancy of the tank, resulting in its ascent, then sprinkle by cooling the working t

11, heat-insulating one from the other components 4 and 5. Falling into the cold component 4, capacity 3, about -20 la of the negative buoyancy of the cmcomlada with excessive buoyancy, rises and is fixed by a magnet I After some time due to heat transfer to component 4, which heat is removed by an external refrigerant or pumped medium (figure 2), the working fluid in the tank 3 is cooled compressed, which leads to a decrease in the volume of the tank 3. When the force is submerged, resulting in its immersion, and periodic pressure decrease in de cFe pumped, whereby it occurs peri odic its suction and delivery to the consumer, characterized in that, in order to expand the functional capabilities due to expansion possibility range

Neither does it exceed. the force of the magnet 17, a reversed change in the mean absolute

the container 3, it is immersed, the passage through the layer 11 of the cold component A into the warm component 5, and fixed on the magnet IB. Then the cycle repeats

During the cycle, there is a periodic change in the volume of the tank 3, which leads to oscillatory deformation of the diaphragm 10 “. As a result of the oscillations of the latter, t occurs periodically to its average absolute temperature, a change in the volume of the pump chamber 7, absorption of the pumped medium into it and discharge of the medium to the consumer.

A lifting device for a fluid-containing body with a vertical working chamber filled with fluid in which a variable volume container is placed is filled on the working fluid, suction and discharge valves, characterized by the fact that the working chamber contains a heat-conducting medium flowing from two components with different densities, the interface of which is located in the middle part of the height of the working chamber, and in the case a pump is completed

When the average temperature of components 4 and 5 changes, and consequently, of the working fluid in the tank 3, when the average volume of the tank 3 increases or decreases and its buoyancy changes, the thermosensitive body 16 in the chamber 13 heats up or cools. volume and through the elastic wall 15 has a corresponding. exerting pressure on components 4 and 5, providing a change in the volume of the tank 3 compensating for the buoyancy drift,

Thus, stable operation and stable characteristics of the device are ensured in a wide range of changes in average absolute temperatures of the working fluid.
