Hydropneumatic piston-cylinder arrangement

Hydropneumatic Piston-Cylinder Arrangement A hydropneumatic piston-cylinder arrangement (100), in particular for use in vehicle suspension systems and for damping movements of a driver's cab of such a vehicle, with a cylinder housing (102) having at least one separating piston (118) arranged therein in a longitudinally movable manner, which separates a first medium space (120), in particular for receiving a working fluid, such as hydraulic oil, from a second medium space (122), in particular for receiving a working gas, such as nitrogen (N₂), preferably in a medium-tight manner, and with a hydropneumatic accumulator (160) which acts on the first medium space (120) in the cylinder housing (102), is characterized in that a piston accumulator (140) with an accumulator housing (156) and with at least one accumulator piston (172) arranged therein in a longitudinally movable manner is provided as the hydropneumatic accumulator (160), that this accumulator piston (172) separates a first accumulator space (182), in particular for receiving the working fluid, from a second accumulator space (184), in particular for receiving an accumulator gas, such as nitrogen (N₂), preferably in a medium-tight manner, and that the first accumulator space (182) is connected to the first medium space (120) in a medium-conducting manner.
