Abstract
In a unit of a piston and a piston rod, a piston and a piston rod are connected with each other in a gas-proof manner. To this end, the piston has a closed bottom and a blind hole, into which a sleeve-shaped section of the piston rod is pushed. By means of a force being applied between the piston and the piston rod, the sleeve-shaped section is provided with a bulging which projects into an annular groove of the blind hole. This serves to attain a connection of the piston and the piston rod by form locking.
