Hydro-pneumatic cylinder is the name of the new generation ofpower cylinders for press and plant engineering applications. Thecylinder is used when high forces are required, for example forpunching, splitting, pressing, stamping, molding, riveting,clamping, compressing or spot welding. In power stroke mode usersare provided with many times the force of a comparable conventionalpneumatic cylinder with the same air consumption.  
 
     Hydro-pneumatic cylinder is designed inthe same way as a double-acting pneumatic cylinder and is alsocontrolled in the same manner. It is equipped with apneumohydraulic pressure booster which generates a power strokewhen necessary depending on the counterforce. The power cylindercan be operated directly from the compressed air network by meansof a pneumatic valve.
