Abstract:
1. An adjustable shock absorber having selectable behavior characteristics, comprising: a first cylinder having a fluid chamber filled with a transmission or damping medium and a compressible chamber and in which an outwardly leading piston rod with a piston for receiving shocks to be damped or compressed is axially displaceable within the first cylinder; a second cylinder having a fluid chamber filled with the transmission or damping medium and an air-filled or gas-filled gas pressure chamber, said fluid chambers of said first and second cylinders being connectable with one another via a communicating channel; at least one additional cylinder having an air-filled or gas-filled gas pressure chamber and a fluid chamber filled with the transmission or damping medium, said fluid chambers of each said additional cylinders being connectable to said fluid chambers of said first and second cylinders via at least said communicating channel; and at least one switch apparatus located at least partly in the communicating channel for blocking or releasing communication between said fluid chamber of said first cylinder and at least one of said fluid chambers of at least one of said second and said additional chambers to select on of a plurality of different shock absorber behavior characteristics.
