  • Patent number: 9291172
    Abstract: An apparatus for generating pulsatile flows includes a liquid vessel capable of containing a liquid, a plurality of revolving mechanisms associated with each other, and a microchannel supplied with a liquid from the liquid vessel. As the plurality of revolving mechanisms rotate, a periodically changing pressure difference occurs between the liquid vessel and the microchannel, thereby implementing a pulsatile flow having a wave functional form in the microchannel. By applying the hydraulic head difference and controlling revolution of the revolving mechanisms based on Fourier cosine series, a minute and precise pulsatile flow of a wave functional form may be implemented by means of simple configuration and fabrication, which may not easily obtained by a conventional pump.

  • Patent number: 4817712
    Abstract: A close fitting piston of a material such as rubber is attached to the end of a rod string such as a sucker rod which is suspended inside a tubing string installed in an oil well. An orbiting mass oscillator is attached to the upper end of the rod string and is operated at a frequency such as to cause resonant standing wave vibration of the rod string. The piston member attached to the bottom end of the rod string is driven by the vibrational energy to in effect form an acoustical piston which is driven by the vibrational energy. This energy is coupled to the surrounding liquid and thence to the surrounding formation to effectively unclog the well and the casing string of contaminants which may be impeding the flow of effluent from the well. The piston means is made long enough so that it operates as an acoustic monopole with both ends of the piston being vibrationally in phase with the vibrational energy traveling in the surrounding liquid medium.

  • Patent number: 4695231
    Abstract: Within a tubing string forming a conduit for a well is a rod string having sonically responsive impeller pump elements mounted thereon. The impeller pumps employ an elongated cylindrical structure which is spaced from the inner wall of the conduit to form an elongated annular liquid filled gap between the impeller and the conduit. The rod is sonically driven so that it vibrates resonantly. Valves are formed in the impeller, which in one embodiment may comprise a series of ball elements, in another, may comprise flexible reeds, these valve elements being opened and closed in response to the sonic energy to implement the pumping action, and in a third embodiment may comprise arcuate segments that are free to expand and contract radially in response to the sonic energy.

    Abstract: A tubing string forming a conduit is installed within a well. Contained within the tubing string and vibrationally isolated therefrom is a rod string. Mounted on the rod string and spaced therealong at intervals which are less than a quarter wavelength at the resonant vibration frequency of the rod string are a series of sonically responsive impeller pump elements. The rod string is suspended in the tubing string from a vibration generator comprising an orbiting mass oscillator. The orbiting mass oscillator is operated at a frequency such as to cause resonant standing wave vibration at the rod string, the vibrational energy causing the impeller elements to drive fluid from the well up the tubing string.

  • Patent number: 4412786
    Abstract: This invention relates to a positive displacement pump. The pump utilizes a source of rotary motion in the back and forth, clockwise, counterclockwise direction. The rotary oscillatory motion drives an annular piston weight mass in a toroidal rotary track, back and forth within the track in combination with at least a pair of one-way valves to pump fluid through the pump. Specially designed electric motors that rock back and forth, without a 360.degree. rotation, for example, may be coupled to a positive displacement pump of this invention. In the medical profession, this pump may be used to pump liquids at a very slow, precise rate to transmit, for example, a variety of medications into a patient.

  • Patent number: 4406587
    Abstract: A positive displacement liquid pump having a free stroking piston slidably positioned within a cylindrical housing is disclosed. A pair of cooperating one-way valves, one valve communicating with a central passage defined by the piston while the other valve communicates with an inlet to the housing, coact to draw in fluid from a source of liquid. As the piston moves away from the inlet the one-way inlet valve opens filling a chamber behind the piston. The one-way valve in the piston simultaneously closes enabling the piston to drive fluid out of the reservoir chamber at an exit end of the housing, the valves acting oppositely when the piston oscillates back toward the housing inlet. The free stroking piston within the pump is set in motion by the oscillatory motion of vibration alone without direct mechanical piston actuation from a power source. The pump may cooperate with a fluid regulator to control flow of fluid from the pump housing.

  • Patent number: 4358248
    Abstract: A sonic pump for pumping fluid from wells and the like. Sonic energy generated by means of orbiting mass oscillators is transferred to a pair of elastic string members which function as transmission lines, one of these string members being tubular and the other being in the form of a rod mounted within the tubular member and being coextensive therewith. The two string members are tied together at appropriate points therealong and acoustically designed and excited by the sonic energy so that they vibrate in unison in a longitudinal resonant standing wave mode of vibration with lateral vibrational modes being effectively minimized. A valve system is installed in the string member which effectively displaces the fluid in the well in response to the vibratory energy such that the fluid is passed into the interior of the tubing string and then pumped up this string to the surface.

Sonic energy is coupled to the tubing string from an orbiting mass oscillator installed thereabove so as to cause vibration thereof at a sonic frequency which is preferably such as to cause resonant standing wave vibration of the string. Check valves are installed in the tubing string and are driven by the sonic energy to effect pumping action. The sonic energy generated in the tubing string is effectively coupled to the wall of the bore hole by means of a plurality of annular pistons installed at spaced positions between the string and the casing. An annulus of liquid is maintained in annular spaces formed between successive pistons, between the inner wall of the casing and the outer wall of the string, the sonic energy in the tubing string driving the pistons so as to develop hydraulic pressure pulses in the liquid.
