Definitions
- the invention concerns a preferably hand operated liquid pump.
- Known liquid pumps function based on the creation and preservation of an oscillating motion in the liquid in the tubing connecting the initial location of the liquid with the point where said liquid must be transferred.
- These pumps provide for an elastic organ consisting of pieces of tubing of traditional elastic material, rubber and india rubber, or of spring powered pistons, or of compressed air capsules.
- the elastic material tubing limits the high pressure levels, and so the capacity and maximum lift possible at levels compatible with the mechanical resistance of the elastic materials used.
- the spring powered pistons can operate for limited periods only due to the wear and tear on the piston gaskets, and the compressed air capsules require frequent maintenance to renew the air pressure.
- the figures show container A equipped with threaded top C, respectively provided with connection tubings B and D; on the inside of container A there are four balls G of alveolar elastic material, such polyethylene with a cellular structure, or neoprene with a cellular structure or the like, preferably but not necessarily enclosed in elastic protective casings H; the small bars or the like, E and F, prevent the spheres from obstructing tubings B and D, a check valve L being applied to tubing B and tubing T being applied to tubing D to connect to the body of the pump Q, equipped with large size double-lipped gasket O, with hydraulic plunger N at the outlet P with one or more small washing openings X in its bottom, the manual operation lever M, the pans R to position and hold the rimmed gasket gasket O, the three, four or more circular or polygonal cylindrical guides S rotating to allow any adjustment, to prevent wear and tear, around the bolts U with threaded ends protruding from the body of the pump where the tight
- the invention functions as follows: when container A is immersed in the"liquid to be pumped and when the body of the pump Q, tubing T and container A are all filled with liquid, operation of the hydraulic plunger N by means of lever M sends pressurized liquid through tubing T into container A; this liquid under pressure compresses the balls G which, thanks to being made of elastic material with an alveolar structure, that is with internal cavities, can be distorted to effect an overall reduction in volume and the accumulation of elastic potential energy, where the variation in volume of the balls is related to the pressure of the liquid, to the elastic properties of the basic material used in construction, to the ratio between the empty and filled spaces in the alveolar structure and to the initial volume of said balls.
- the plunger is raised to release gasket O, the compressed balls expand to expel a volume of water from the container equal to that put in previously, and that is equal to the variation in volume of the compressed balls, and sends said voluem in tubing T with a kinetic energy equal to the elastic energy imparted to the balls in the compression phase.
- the liquid running through the tubing T continues its motion for a time, aspirating a certain quantity of liquid from the check valve L and expelling an equal quantity of liquid from the opening P, through the opening left above the gasket 0 of the hydraulic plunger N once it is raised.
- the mass of elastic alveolar material may be concentrated in a different number of balls rather than 4, for instance in one ball only as in fig. 2, or in balls shaped differently (lengthened or non-spherical) as in fig . 3, or shaped as hollow cylinders with the container folded as in fig. 4, identical in function, or in several bodies of any shape.
- the blocks of elastic material with an alveolar structure may be enclosed in coverings of non-alveolar elastic material, of the same chemical nature or not, both to protect the principle elastic material from any chemical attack of the liquid and to prevent the danger that over time the liquid penetrate in the cavities of the elastic mass, thus lowering its capacity to change volume.
- a marked advantage of the invention is the fact that the overall elastic property may be obtained exactly as desired by selecting the initial volume of the balls, their number, the ratio between hollow and filled spaces, and a more or less elastic base material.
- the elastic organ may be constructed with a minimum transverse bulk, at the least no greater than that of the tubing, allowing several elastic organs and so several independent pumps even in wells of small diameter.
