Abstract

A piston rod connected at one end to a piston slidably arranged in a cylinder projects with its other end through an opening in an end wall of the cylinder beyond the latter and a fork-shaped member is connected by a friction weld, that is without adding welding material or external heat, to the other end of the piston rod.
