Abstract
A shock absorber comprises a first cylinder including an inside bore; a piston dividing the inside bore of the first cylinder into a first chamber and a second chamber; a piston rod which extends within the first chamber; a second cylinder surrounding the first cylinder; a first connection passage arranged to connect the first chamber to a location outside of the shock absorber; a first tube member defining a second connection passage connected with the second chamber at the second end of the first cylinder; and a damping device comprising at least one valve element, the damping device being disposed between the second chamber and the second connection passage. The piston is configured to separate the first and second chambers so that the first and second chambers are not in fluid communication with each other through the piston.
