Abstract
An adjustment assembly has two coaxially mounted cylinders fitting into one another with a piston displaceably mounted within the inside cylinder and dividing the inside cylinder into two fluid filled housing chambers. The piston is connected to a piston rod which is guided out of one end of the cylinder in a sealed manner. A pressure medium chamber is provided in the annular space between the cylinders and is separated in a fluid tight manner from fluid filled parts of the annular space by two axially displaceable separating pistons. The lower housing chamber has a fluid passageway to the lower portion of the annular space and the upper housing chamber has a fluid passageway to the upper part of the annular space. The inner cylinder may be axially displaced from outside the assembly to seal or open the upper passageway thus locking or unlocking the piston.
