Shock-absorbing piston made up of dissimilar joined parts, blank for the piston and method for manufacturing the piston

摘要

A shock-absorbing piston, a blank for the piston and a method for producing the piston include two parts being constructed radially symmetrically, but formed with outer and inner parts differing from each other. This offers great variability in the shaping of the functionally essential elements of the shock-absorbing piston.
