Abstract
A vibratory pump includes an oscillator that is connected to a plunger mounted within a housing submerged beneath the surface of a fluid to be displaced. The oscillations of the plunger selectively communicate an outlet for the pump with inlet openings on the housing. The selective communication creates a slight vacuum in the pump that enables the fluid to be moved by the pump without generating any significant back pressure in the outlet fluid flow from the pump. The pump can also be configured to operate in a dual stroke mode where an outward flow of fluid from the pump is generated during both the downward and return strokes of the pump.
Claims15
A dual action pumping apparatus adapted to be attached to a vibration generator, an apparatus comprising:
- a housing including an upper end, a lower end and two spaced sets of fluid openings disposed between and adjacent to each end;
- an outlet tube having a pair of inlet legs, each inlet leg secured to the housing adjacent one of the upper end or lower end, an outlet leg secured to each of the inlet legs opposite the housing, and a collector joining each of the outlet legs opposite the inlet legs, wherein the collector does not include a valve;
- and
- a plunger having top end and bottom end, that is slidably disposed within the housing and attachable to the vibration generator, a plunger capable of alternately obstructing one set of openings in the housing to pump a fluid in which the apparatus is summersed through the inlet leg positioned adjacent the obstructed openings and to open the remaining set of openings to enable fluid to flow into the housing to be pumped.
A pump apparatus connectable to a vibration generator for pumping a fluid, the apparatus comprising;
- an enclosed housing having an upper end and a lower end, a shaft opening disposed in the upper end, a chamber opening disposed in the lower end, and a plurality of fluid openings disposed between the upper and lower ends;
- a chamber disposed in the chamber opening and including an inlet end within the housing and an outlet end opposite the inlet end;
- a plunger disposed within the housing a slidably mounted to the chamber, the plunger including an open end position within the chamber and a closed end opposite the open end, and at least one fluid passage disposed between the open and closed ends;
- a sealing member disposed around the plunger adjacent the closed end and engageable with the inlet end of the inlet end of the chamber;
- a shaft connected to the closed end of the plunger that extends through the shaft opening in the housing and is adapted to be connected to the vibration generator.
A method for pumping a fluid comprising the steps of:
- a) providing a pump apparatus including a housing having an upper end and a lower end joined by at least one side wall, the upper end including a shaft opening, the lower end including a first fluid outlet, at least one first fluid opening in fluid communication with the first fluid outlet, a plunger disposed within the housing, the plunger slidably mounted with respect to the housing and having an open end adjacent the outlet, and a closed end opposite the open end, and a shaft connected to the closed end of the plunger and extending through the shaft opening;
- b) connecting a vibration generator to the shaft;
- c) placing the apparatus in an amount of fluid to be pumped;
- and
- d) engaging the vibration generator to enable the plunger to selectively obstruct and expose the at lest one first fluid opening.
