Abstract:
A method of controlling a fluid pump. The pump has a plurality of oscillating pistons that travel along a central axis of a piston sleeve. A plurality of pistons is of similar mass within a piston sleeve are provided, and adjacent pistons are positioned to be 180 degrees apart in phase oscillations. An electric coil is provided for each piston, and the position of adjacent pistons is determined. The current to one of the electric coils for a piston is adjusted to maintain the 180 degree difference in phase between oscillations of adjacent pistons.
