ABSTRACT:
A press assembly includes a hydraulic cylinder assembly having first and second chambers and respective piston and rod assemblies therein. The rod of the second assembly is arranged to enter the first chamber and thereby raise the pressure therein. Initially, fluid flows into the first chamber, forcing the first rod to exert a force on a work object. When a predetermined pressure is reached within the cylinder, fluid is introduced to the second chamber, and causes the second rod to move into the first chamber, which raises or boosts the pressure in the first chamber.
