Definitions

  • This invention concerns a pump for liquids constructed so as to achie-ve an oscillatirgsystem in which the mass consists of the mass of liquid itself.
  • volumetric that is, piston, membrane, case- work pumps
  • fluidodynamic that is, centrifuge, axial pumps
  • suction pumps may not be used. Rather, only sucking and forcing pumps or pressure pumps may be employed placed near the water or even submersed in it.
  • This patent is based on the creation and maintenance of an oscillatory motion of the liquid in the tubing connecting the original location of the liquid with the point to which it must be transferred.
  • the pressure of the liquid in the various points of the tubing varies cyclically, passing alternately from higher to lower pressures than the liquid would have in absence of the oscillations.
  • a pressure cycle is achieved with an amplitude such that the minimum pressure achieved periodically at the starting point of the tubing is lower than that of the liquid to be pumped.
  • the maximum pressure achieved at the end point of the tubing is higher than that of the surroun dings.
  • the drawing shows tube T of the pump equipped at its upper end with the liquid exit port L, placed at the height H above the free surface of the water, and with hydraulic piston A operated manually by lever P or by some other mechanical and/or motor arrangement able to supply energy for the operation.
  • the piston's seal is guaranteed by the presence of gasket G, and its course is such that at the maximum dead point it disengages from gasket G so as to freely connect tube T and port L.
  • gasket G At the other points on its course, it is inserted in gasket G so as to separate port L from tube T and to push on the liquid.
  • tube T is equipped with the crop end of elastic tube B (rubber, caoutchouc or the like) and with unidirectional valve V to allow water to enter but not leave the tube.
  • the crop end of elastic tube B may be replaced by other suitable elastic organs, such as spring connected pistons, air chambers, membranes, etc.
  • exit port L, gasket G and valve V may be made differently, and the liquid itself may be other than water.
  • the invention functions as follows: water tube T is filled up to the level of piston A and the water is placed in oscillation throgh the alternating motion of piston A.
  • the oscillating elastic system consists of the mass of water in the tube and elastic organ B.
