Air Powered Hydraulic Cylinder Features

Schematic representation of the TOX®-Powerpackage functioning

I  Fast approach:

The main control valve A is actuated. The working piston extends in a fast approach until it meets resistance at any point. It stops and the power stroke valve B switches. Air streams into the intensifier chamber.

II  Powerstroke:

The intensifier piston closes the high pressure chamber and compresses the oil in the working area up to 400 bar. This oil pressure acts on the rear of the working piston 1 and generates the powerstroke.

III  Return stroke:

After switching the main control valve A, the powerstroke valve automatically vents the remove chamber C. The working piston and the intensifier piston return to their original position.
