Abstract: A rotational power input is converted into a linearly oscillating power output through the use of counter-rotating nested eccentrics. The outer eccentric is connected to an input end of a connecting rod, which is in turn connected at an output end thereof to a piston of a piston pump. The piston is constrained to translational movement along an axis D. Drive gears are rotationally fixed to each of the eccentrics and geared to each other through an intermediate pinion having a rotational axis B. An angular position &bgr; of the pinion axis B relative to the axis D determines the output oscillation stroke length and flow rate of the pump. An actuator is geared to a pinion bracket that holds the pinion. The actuator can be actuated on-the-fly to alter the angle &bgr; and pumping rate of the pump.

Abstract: A flow divider, particularly for use in uniformly dividing a single incoming stream of liquid fertilizer into multiple outlet streams. The flow divider features a housing having a bore therein; a distribution sleeve which fits within the bore; and a distribution needle which slides within the distribution sleeve to evenly divide the incoming flow. Flow enters a distribution chamber formed between a tip portion of the distribution needle and the distribution sleeve, preferably flowing over a series of circumferential ribs located on the tip portion, and accelerates through a narrowing, flow-accelerating region between the distribution needle and the distribution sleeve. The flow is then discharged through a series of orifices in the distribution sleeve and out through a series of flow passageways radially arranged around the flow divider. When fluid flow supply is terminated, no pressure is developed and the distribution needle automatically returns to a closed position in which the inlet orifice in the distribution sleeve is closed by the tip portion of the distribution needle, and the outlet flow orifices in the distribution sleeve are closed by means of the body portion of the distribution needle.
