A TTORNEY Patented Mar. 7, 1933 UNITED STATES PATENT OFFICE CARL GEORG HUNTERS, OF STOCKHOLM, SWEDEN, ASSIGNOR, BY MESNE ASSIGNMENTS, '10 ELEGIROLUX SERVE CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE HEAT PUMP Application filed May 5, 1981, Serial No. 585,105, and in Germany September 27, 1930.
This invention relates to a method of and apparatus for pumping liquid from a lower to a higher level and more specifically to a vapor liquid pump for circulating the liquid in one direction without the use of valves.
The invention will be readily understood by reference to the following description taken in connection with the accompanying drawing which shows schematically a vapor liquid pump contemplated by this invention.
In the drawing a pump vessel contains a liquid, for instance water, which is to be circulated and is adapted to be heated by any desired m'eans such as gas burner 11. A container 12 located at the level to which it is desired to raise the water is connected to the pump through the rising pump pipe 13 which is connected at one end to the lower part of the pump vessel 10 and terminates at its other end in a gooseneck 14 which is connected to the container 12. A receiver 15 is connected at its lower part to a pipe 16 which extends into the pump vessel 10 terminating near the bottom thereof as shown. The pipe 16 is provided with baflie plates 17 or similar devices for creating a high resistance to liquid flow through this pipe. The hi h liquid flow resistance of the pipe 16 may be obtained in any of several known ways, for instance, by making the pipe of a very small cross section as a capillary tube.
When the pump vessel 10 is heated the liquid contained therein vaporizes and vapor collecting in the upper part of the vessel 85 creates a pressure which tends to force the liquid out of the vessel through both the pump pipe 13 and the high resistance pipe 16. Depending on the vapor pressure in the pump vessel a certain amount of liquid is forced out of the vessel per unit time and in accordance with this invention the flow resistance of the pipe 16 is made such that when 'a certain amount of liquid is forced out per unit time through pipe 16 a velocity is created such that corresponding flow resistance in terms of liquid column height is greater than the lifting height from the pump vessel 10 to the container 12. The difl'erence between the quantities of liquid forced through the pump pipe 13 and the resistance pipe 16 debe made in the construction and'arrangement pends on the relative resistance to liquid flow in these pipes. The total resistance in pump pipe 13 comprises the static difference in level of the liquid in pump Vessel 10 and the highest point of the pipe 13 and the dynamic flow resistance of this pipe. The total resistance in pipe 16 comprises the static difi'erence in levels between the liquid levels in the pump vessel 10 and the receiver 15 and the dynamic flow resistance in pipe 16.
When the desired amount of liquid has been pumped into the container 12 the pressure in the pump vessel is lowered, for instance by removing the heat, and the liquid which was forced into the receiver 15 through pipe 16 during the pumping cycle flows back to the pump vessel again by gravity. The liquid in the container 12, however, cannot return due to the gooseneck 14 at the upper end of the pumping pipe 13. The quantity of liquid pumped into the container 12 can be replaced in the pump vessel .in any suitable manner as for instance b supplying receiver 15 through pipe 18. f
repeated circulation of the li uid is desired such as in absorption type rei rigerating apparatus, the liquid pumped into the container 12 may be returned directly, or after usethereof, to the receiver 15 through the pipe 18. The arrangement described is only .exemplary and other modifications and variations in design will be apparent to those skilled in the art, for instance, instead of turning off the heat the vapor pressure in the pump vessel may be varied in otherways as by periodically relieving the pressure through a valve which may conveniently be a suitable liquid seal. Many other modifications ;may
