Abstract
A pressure cylinder includes a working cylinder and an intensification cylinder that is divided by a separator block. A working piston is arranged in the working cylinder and connected to a working rod that extends to an end portion. An intensification piston and an intensification rod are arranged in the intensification cylinder. A pump is configured to provide a pressurized hydraulic fluid to the pressure cylinder. A fluid reservoir is configured to supply a hydraulic fluid to the pump. A first valve is configured to selectively regulate hydraulic fluid flow between the pressure cylinder and the fluid reservoir and the pump. A second valve is configured to selectively regulate fluid flow between a first valve and the advance intensification chamber. A controller is in communication with the first valve and the second valve. The controller is configured to coordinate movement of the working piston and the intensification piston.
