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.

Abstract: A container filling machine comprises a plurality of filling stations each including a container platform which is raised and lowered by a cam controlled elevating mechanism, for providing bottom-up filling; 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; and an adjustable crank lever mechanism is included in the cam controlled pumping mechanism for providing adjustment of the volume of fluid being pumped. Operating in common with the filling stations are a pair of cams for operating the valves of each station, and in combination with each cam-controlled pumping mechanism provide greater than 180.degree. of machine time for continuously filling a container during the discharge cycle for each station.
