Description

The invention relates to the field of heat pumps, applicable, for example, when supplying a pressurized liquid fuel to evaporative packagings in lighting or heating devices and operating by periodically evaporating a part of the fluid being raised and subsequently co-removing vapor that forms, in order to create a vacuum for sucking fluid and injecting the vapor into a fluid. destination.

In the thermal pump according to the invention, the vessel serving to heat the liquid is formed from a system of tubes which are connected to a liquid filled with a pressurized tube, divided to enhance the condensation of liquid vapor, a partition into two channels, one of which is connected to the system tubes and about the place of supply of the injected fluid, and the other with a reservoir for the injected fluid.

 In FIG. 1 shows a vertical section of a pump in connection with a burner for lighting devices; FIG. 2 is a cross-section of it in I-1

FIG. one; FIG. 3-6 are diagrams illustrating the operation of the pump pipe system.

The thermal pump is equipped with a vessel for heating a liquid, consisting of a system of tubes, and, o, connected to a tube, which is partition I, to enhance the condensation of liquid fluids, divided into two channels, p and u, communicating with each other through opening y. Channel p through the exhaust valve q p pipe S is connected to the place of injection of the injected fluid - chamber i. The channel and, adjacent to channel p, is communicated through the outlet clanap with camera v. a sablogenic filter w and connected by pipeline S with a reservoir for the injected fluid. At the top of the partition t there is a small hole z for air to escape.

Chamber g, in which a tubular element 2, closed on top and acting as an air buffer, is loosely connected by its upper end with tip 3, inside which spindle 4 passes, ending with needle 5 and controlled by eccentric 6. Chamber g,

and camera v, each separately, communicates with channels 7 and 8, which are located in housing 9. Channel 7 can be closed or JKO can be connected to channel 11 or channel 8 by means of Vran 16, while channel 8 is in the communicating with inlet duct Yu, connected to a reservoir for high pressure, and not shown in the drawing. The storage compartment 3 goes into the mixing chamber 12, to which, in the case of using a pump for a lighting device, the grid 13 and into which air flows through the channel 14.

To the lower end of the tube m is fixed a metal plate 15 for heating the tube system t, n, o from the heated part of the burner.

In order to eliminate the deposition of solid carbon viut tube m and after prolonged use, tube m should be periodically washed with liquid from tube n, which can be achieved by shaping the tube m with an appropriate shape or by placing a deflector in it.

The diagrams shown in FIG. 3-6 depict the operation of the tube system m, n, o and channel p, with the lower end of the channel p assumed to be in direct communication with the reservoir for the liquid and the valves q and x and the viuse channel are omitted for clarity.

Heat is continuously communicated to the lower tube of the tube, and the entire system is assumed to be a poplar fluid, such as kerosene. Kerosene bunks start to form at location 17 (Fig. 3), and conditions are created, depicted in Figs. 4, when kerosene begins to exit through the upper end of the drip, dripping p in accordance with the number of vapors generated in the gauge tubes type. The hydrostatic nanor supported by the vapor pressure of kerosene is denoted by ti. When heated, the vapor enters the tube o (fig. 5), having a smaller cross section than caial p and tube m or n, which creates a rapidly increasing hydrostatic pressure until the pair exit through the upper opening of the tube o to be condensed cold kerosene inside the channel p. As soon as the condensing action begins, the pressure immediately begins to fall in the space filled with vapors in the tubes,

m and p, which is accompanied by a rapid inflow from the source of supply of cold kerosene into the tube n (Fig. 6), overflowing through the bent part connecting the tube n with the tube t. This, in turn, causes even stronger and very fast vapor condensation so that the whole space inside1) and the tubes m and II is once again completely filled with cold kerosene. Cold kerosene enters the tube n to compensate for the sudden drop in vapor pressure with such speed that it instantly fills the tubes n, m and o, eliminating the possibility of a stop that could be caused by any unilateral body that happened to be in the tube o. This effect is facilitated by appropriately positioning the inlet opening (Fig. 1).

The vapors passing through the tube o blow bubbles through the liquid into the upper part of the channel p, which bubbles form a series of free surfaces instead of a free surface in a horizontal plane.

In practice, this cycle automatically repeats and, therefore, the Teilote eaters automatically create the necessary fluid pressure for the pump, thereby eliminating the need for initial pressure to start the pump into action.

In order to start the transfer, it is only necessary to start heating the closed end with the lower non-drainage part of the tube system,,,,, and as soon as pumping starts, the mixture that flows into the grid 13 can be ignited. The heat of the mesh then automatically maintains suction in action.

For initial filling of the system t, p and o with liquid, turn valve 16 half a turn so that channels 7 and 11 are connected to each other. Finally, a hand pump or other similar device is connected with which, but channel 10, is filled with liquid.

In order to extinguish the lamp, it is sufficient to simply flush edge 16 so as to bring out channels 7 and 11 into the atmosphere, as a result of which a small amount of fuel from vessel v will flow out through channel 11 and the supply pressure will stop. Pasos works even if

The fuel supply tank is located at a level well below the outlet tip. Since the pipe connecting the channel 10 of the liquid supply tank is under reduced pressure (below atmospheric pressure), in the event of a breakdown or crack in this pipe, a liquid leak never occurs. To regulate the amount of fluid sucked in a unit of time, a spring-adjustable valve can be placed between tank v (Fig. 1) and channel 8.
