Abstract
An apparatus can include a central member between a first fluid section and a second fluid section, wherein the central member, first fluid section, and second fluid section define a longitudinal axis thereon, at least one first fluid section driving member in mechanical communication with the central member, at least one second fluid section driving member in mechanical communication with the central member, an oscillating member in mechanical communication with the central member configured to oscillate the central member along the longitudinal axis, a pump inlet in fluid communication with a fluid source, and a pump outlet.
Claims20
An apparatus comprising:
- a central member between a first fluid section and a second fluid section, wherein the central member, first fluid section, and second fluid section define a longitudinal axis thereon;
- at least one first fluid section driving member in mechanical communication with the central member;
- at least one second fluid section driving member in mechanical communication with the central member;
- an oscillating member in mechanical communication with the central member configured to oscillate the central member along the longitudinal axis;
- a pump inlet in fluid communication with a fluid source;
- a pump outlet;
- at least one connecting guide shaft, wherein the at least one connecting guide shaft is attached to the first fluid section and second fluid section, and wherein the at least one connecting guide shaft is configured to guide the central member along the longitudinal axis;
- and
- wherein the at least one connecting guide shaft is at least three connecting guide shafts, and wherein the at least three connecting guide shafts guide the central member along the longitudinal axis by extending through a plurality of holes in the central member.
