ABSTRACT:
A hydraulic synchronous driving mechanism provided with at least two piston-cylinder assemblies, each having a bottom chamber and a ring chamber and the piston rods of which engage a counterdevice adapted to synchronously load piston rods mutually in opposite directions, a hydraulic fluid circuit provided with at least a pump and a reservoir, whereby there are pair-wise arranged volumetric pump-motors in fluid lines throughconnected to the bottom chamber of the one cylinder and the ring chamber of the other cylinder, which pump-motors are mutually coupled for a constant supply ratio, while the fluid line sections extending from the pump-motors to the cylinders are throughconnected to only one cylinder chamber.
