Function
From the pressure connection in the end cover, compressed air is introduced into the chamber between the end cover and the last piston. Via the air channel in the piston rod the extension cylinders of all the other cells acquire the same pressure in the chambers between the cylinder surface and the pistons. The area of the extension cylinder, between the piston and the cylinder surface, are ventilated through neighbouring bores. The area between the piston and the cylinder surface of the basic cell is ventilated by a second pressure connection.

The power at the end of the piston rod is calculated as the piston force of the basic cell and the sum of the piston forces of the extension cells. 

The principle of the HG - multicylinder as described here, is as a power cylinder. The return pressure, which is available for the return of the piston rod, is the pressure on the piston rod side of the piston faces of the basic cell and the additional cells. 

If more than 5 additional cells are required, we recommend a second base cell, as the friction loss because of the seals is high and the available pressure for return is only a fraction of the operating pressure.

Options:

• piston rod guide
• 2 base cells  
• externally extended rod
• special piston rod
• extension cells with retained exhaust
• piston rod with rotation prevention
• switch rod with trip cams
