Abstract (en)
[origin: EP1496009A1] Hydraulic spring, especially for a cantilever arm, has at least a hydraulic cylinder (10) with chambers (14, 16), a control valve (22) that is connected to at least one of the chambers via a hydraulic line (18, 20) and provides a connection to a hydraulic oil pump (30) and tank (28). Linking the two chambers is a connection line (40). A control unit (54) monitors and regulates the position of the cylinder piston using a sensor (50) and a pressure limiting unit (44) connected to the connection line.
