Control piston for control unit, particularly of automatic transmission units, has annular piston body, where outer or inner seal is formed on piston body such that half contour of seal base adheres at partial area of outer or inner contour

摘要

The control piston (20) has an annular piston body (50), which is formed around a center axis. An outer seal (70) is arranged at an outer contour of the piston body. An inner seal (140) is arranged at an inner contour (144) of the piston body. The outer seal or the inner seal is integrally formed on the piston body such that a respective half contour of a seal base of the outer seal or the inner seal adheres at a partial area of the outer contour or the inner contour of the piston body. An independent claim is included for a method for manufacturing a control piston.
