ABSTRACT:
A fluid pumping system including a variable-volume, fluid-reception chamber having an inlet conduit leading from a fluid supply site and an outlet conduit leading to a fluid delivery site. An elongated plunger body is drivingly coupled with the chamber and linearly reciprocable along its longitudinal axis so as to alternately expand and contract the volume of the chamber, thereby alternately drawing a fluid into the chamber through the inlet conduit from the fluid supply site and pumping the fluid through the outlet conduit towards the delivery site. The linear reciprocation of the plunger body is effected by an electromagnetically operated drive, preferably a linear motor drive, at a rate of reciprocation in the range of 0.01 to 10 Hz.
