A subassembly for the amplitude-dependent absorption of shock, especially in a dashpot for a motor vehicle with a piston and an oscillating piston rod. The piston () is accommodated in a housing (), partitioning the housing into two compartments (&), and travels up and down inside the housing, radially aligned and axially subject to motion-limiting tension, on the end of the piston rod (). The object is a simple and reliable subassembly that takes up little additional space. The piston is accordingly axially tensioned between two springs (&).

Subassembly for the amplitude-dependent absorption of shock

A piston for a hydraulic dashpot. The piston () is mounted on one end of a piston rod (), travels back and forth inside a cylinder (), which it divides into two chambers (&), and has a body () provided with axial channels (&), each of which can be opened and closed at the end by a one-way valve in the form of a cup spring or stack of cup springs (&), independently adjusting their tensions for both the compression and the suction phases. The cup springs (&) rest against and in alignment with the body, and the tension is adjusted by deforming the body resiliently or plasticly against its contact surface.
