Self-pumping hydropneumatic shock absorber with internal level control, with an oil-filled working cylinder under the pressure of gas cushions and with a damping piston, which is attached to the end of a hollow piston rod and can slide back and forth in the working cylinder, the hollow space in the piston rod serving as the pump space of a pump rod attached to the working cylinder. Oil is drawn from a reservoir space when the piston rod travels outward and into the working space when the piston rod travels inward, and where a control opening is provided in the pump rod to compensate for pressure differences between the working spaces. At least one throttle acting as a function of pressure is provided in the pump space between the high-pressure gas cushion and the low-pressure gas cushion.
