Patent ID: 7544048

Claim:
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.
