Abstract
A hydropneumatic piston-cylinder assembly, in particular for use as a suspension strut in vehicle suspension systems, includes a cylinder housing () and a piston () guided for axial movement in the cylinder chamber () of the cylinder housing. The cylinder chamber is filled with a hydraulic fluid. The piston has a piston rod () on one piston side (). The piston rod extends out of an end of the cylinder chamber () in a sealed manner. The hydraulic fluid, which is located in the cylinder chamber () on the side of the piston crown () facing away from the piston rod (), can be brought into operative connection with a pneumatic spring accumulator (). The pneumatic spring accumulator is a piston-type accumulator (), which is arranged in the cylinder housing ().
