  • Subassembly for the amplitude-dependent absorption of shock
    Patent number: 7201260
    Abstract: 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 (3) is accommodated in a housing (2), partitioning the housing into two compartments (4 & 5), and travels up and down inside the housing, radially aligned and axially subject to motion-limiting tension, on the end of the piston rod (1). The object is a simple and reliable subassembly that takes up little additional space. The piston is accordingly axially tensioned between two springs (17 & 18).
