ABSTRACT:
A self-pumping, hydropneumatic, telescopic, spring damping device with internal level regulation, especially for automotive vehicles, includes an oil filled working chamber and a working piston with damping devices, the working piston rod being hollow and forming a pump chamber for a pump rod which automatically pumps oil from an oil reservoir into the working chamber. A control opening permits flow from the work chamber to the oil reservoir when the desired oil level is exceeded. A gas cushion in a gas spring chamber connected with the working chamber pressurizes the oil in the working chamber. The gas spring chamber includes a separating piston and is connected axially to the working chamber in the region of a flexible or elastic partition which supports the pump rod. The partition includes communicating passages. A pump suction tube communicates a pump rod cavity with the oil reservoir, and is yieldable with respect to movements of the flexible partition. The separating piston of the gas spring chamber is recessed such that upon disposition of the separating piston in the region of the partition the pump suction tube can be accommodated by the recess. The device may be made as a modular system in which major components are made as a standard module, and other functional components, such as the oil reservoir chamber and the gas spring chamber are made as variable modules according to particular needs. The modules can be separately disposed and interconnected by tubular conduits.
