ABSTRACT:
A cam-controlled pumping mechanism operating a piston pump for drawing fluid into the pump during a charge cycle, and pushing the fluid out of the pump during a discharge cycle includes an adjustable crank lever mechanism for providing adjustment of the volume of fluid being pumped. The profile of the track for the cam of the cam-controlled pumping mechanism can be changed to program the exit velocity of the fluid in accordance with the viscosity of the fluid.
