Differential piston for hydraulic press, has stepless transition zone between piston head and piston shaft

摘要

A radially and axially symmetrical shaped part in the transition region between a piston head (2) and a piston shaft (3) comprises a continuous, stepless transition zone from the outer periphery of the piston head, to the outer periphery of the piston shaft. The largest diameter of the transition zone is the diameter of the piston head, and the smallest diameter of the transition zone is the diameter of the shaft.
