The TOX® PRESSOTECHNIK air to oil cylinders, also known as the TOX®-Powerpackage, are energy-saving, pneumatically operated, air hydraulic cylinders that feature an integrated oil system and automatically activated powerstrokes.
Capacities and technical specifications include press forces from 2 to 2000 kN, powerstrokes up to 69 mm (with longer powerstrokes available using the split X-KT system), and total strokes up to 400 mm. Patented characteristics of this hydro-pneumatic cylinder include the bypass system, absolute air-oil separation feature, and the hydraulic return stroke damping systems.
If you need any of the following, please contact us:
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.
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.
