- the energy saving Pneumatic intensifier with integrated oil system and automatic activated powerstroke.
I Fast approach:
The main control valve a) is switched. The working piston 1 extends at high speed until resistance in encountered at any point of the stroke. This resistance effects the changeover of the assembled power stroke valve.
The intensifier piston 2 closes the high pressure chamber and compresses the oil in working area 5 up to 400 bar. This oil pressure applies pressure to the back of working piston 1 and brings about the powerstroke.
III Return stroke:
After the changeover of main control valve a) the powerstroke valve d) automatically vents chamber e). The working piston 1 and the intensifier piston 2 return to their initial position.
