Abstract
An adjustable-length gas spring comprises a housing and a piston rod led out of the latter, on which a piston is disposed, dividing the housing into two partial housing chambers. Provision is made for a valve for the partial housing chambers to be connected with each other, the valve comprising a valve-operating lever, which is arranged pivotably at right angles to its longitudinal direction and a valve seat of which, when the lever is pivoted out of a position of rest into a position of opening of the valve, can be lifted off a seal, while forming a gap that connects the partial housing chambers with each other.
