3-,5-,7-,9-,11- etc. chamber cylinder construction (expansion possible up to strength limit)

摘要

The cylinder design includes an internal cylinder with a cylinder bottom (52) on its inner end, with the hollow piston rod (53) passing through a seal in it. There is an external cylinder with an outer cylinder bottom fixed to the hollow piston rod and sealed to the inner cylinder, forming first and second additional chambers (e.g. a2, a3, b1, b2, b3).
