ES214157U - Oleo-pneumatic disposition of energy absorption for telescopic bitubular damper for vehicles. (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

An oil-pneumatic energy-absorbing arrangement for two-tube telescopic shock absorber for vehicles, constituted by an inner cylinder filled with fluid and a slideable piston inside it, the piston and one end of the cylinder being provided with valves for the passage of the fluid in one or another direction during the compression and expansion or traction strokes, characterized in that the piston valve allows the passage of the fluid, in the compression stroke, from the chamber located in front of said piston to the chamber in which the piston rod is located. The cylinder valve at the end of the cylinder that allows the passage of fluid in the expansion stroke, from the compensation chamber to the chamber in front of the piston, are both constituted by a floating steel strap washer that closes the fluid passage and an elastic O-ring interposed between said floating washer and a fixed rear washer with exit holes, of t in the manner that the pressure of the fluid on the closing face or seat of the washer causes the elastic compression of the O-ring and, therefore, the opening of the valve.
