Self-pumping hydropneumatic spring strut for motor vehicles, has internal level control, where one of pump rod receiving end of piston rod is formed as rotationally asymmetric functional body

摘要

The self-pumping hydropneumatic spring strut has an internal level control, where one of the pump rod receiving end of the piston rod (4) is formed as a rotationally asymmetric functional body. The piston rod and the pump rod are arranged relative to each other in a rotatable manner.
