<p>A highly efficient fluid pump and pumping method are disclosed. The pump includes a cylinder, a piston in the cylinder defining a first and second volume in the cylinder, and a motive actuator for driving reciprocatively a rod attached to the piston at a rate of substantially sinmx for x=0 toπ, where m is a number greater than one, during a power stroke of that piston.</p> |
