Abstract
An overall pump assembly for smoothly pumping a compressable liquid from a supply is disclosed herein along with two intensifiers which form part of the assembly and a control arrangement for driving the intensifiers in specific phase relationship to one another. Each of the intensifiers includes its own reciprocating piston and a control device interconnected in feedback relationship with the piston in order to follow the latter through its movement. In each of the specific intensifiers disclosed, its piston and control device are interconnected by cable means configured to cause the control device to rotate about its own axis in a manner corresponding to the movement of the piston.
