A vibratory pumping machine including a pumping chamber disposed within a housing for the machine having an inlet tube that is insertable into a container having a liquid therein to withdraw the liquid from the container upon actuation of the pumping mechanism also located within the housing. The chamber includes an oscillating rod that engages a resilient outlet member to form a vacuum within the chamber which draws the liquid upwardly through the tube into the chamber for dispensing through the outlet member. A mechanism including the pumping chamber can be utilized to withdraw liquids from within container of various shapes and sizes, as well as to introduce other fluids, such as gases, into containers containing such liquids.

We hereby claim: 1. A vibratory pump comprising: a) a rigid housing; b) a vibration generating mechanism disposed within the housing; c) a rigid pumping chamber disposed within the housing adjacent the vibration generating mechanism and defining an enclosed interior space, the pumping chamber including at least one fluid inlet and a fluid outlet each extending through the pumping chamber, the at least one fluid inlet communicating with the interior space through an inlet opening in the pumping chamber and extending outwardly from the pumping chamber, the at least one fluid inlet adapted to be inserted into a fluid to be pumped to draw the fluid into the pumping chamber within the housing; and d) a rod disposed within the housing and operably connected to the vibration generating mechanism at one end to enable the rod to move in direct correspondence to the oscillation of the vibration generating mechanism and positioned within the pumping chamber at the opposite end, the opposite end selectively and directly engageable with the fluid outlet during operation of the vibration generating mechanism, wherein the fluid outlet includes an enclosed outlet chamber defining an enclosed inner space and having an inner end positioned within the enclosed interior space within the pumping chamber and including a central opening, and an outer end extending outwardly from the enclosed interior space within the pumping chamber, wherein the rod includes a plate opposite the vibration generating mechanism that is engageable with the central opening, wherein the plate includes a central portion having a diameter less than the diameter of the central opening and an outer portion having a diameter greater than the diameter of the central opening, and wherein the outer portion includes a sealing member that is sealingly engageable with the inner end of the outlet chamber. 2. The pump of claim 1 wherein the central opening has a conical surface. 3. The pump of claim 2 wherein the rod includes a plate opposite the vibration generating mechanism that is matable with the central opening. 4. The pump of claim 3 wherein the plate is formed of a resilient material. 5. The pump of claim 1 wherein the inner end includes a resilient diaphragm positioned over the central opening, the diaphragm including a central aperture. 6. The pump of claim 1 wherein the plate is positioned within the inner end of the outlet chamber. 7. The pump of claim 1 wherein the at least one fluid inlet is formed as at least one inlet tube that extends outwardly from the pumping chamber. 8. The pump of claim 7 wherein the at least one inlet tube is formed from a generally resilient material. 9. The pump of claim 7 wherein the housing includes an engagement member disposed on the housing that is engageable with a fluid-holding container. 10. The pump of claim 1 wherein the vibration generating mechanism includes a switch extending through the housing.
