Self-pumping hydropneumatic shock absorbing strut with internal level regulation, with a work cylinder which is filled with oil and is under the pressure of gas cushions, and with a damping piston which can be displaced in this work cylinder. The damping piston slides on the end of a hollow piston rod, the cavity in the piston rod acts as a pump cylinder of a pump rod which is fastened to the work cylinder. Whereby, when the piston rod is extended, damping medium is sucked out of a reserve chamber by way of a suction valve, and when the piston rod is inserted, damping medium is transported into the work chamber by way of a non-return valve and a ring-shaped gap which is formed between a control sleeve and the hollow piston rod. Whereby the pump rod is fastened so that it can move axially, radially and/or with free angular movement in the end wall of the work cylinder.
