Abstract (en)
[origin: EP1342849A2] The device has at least one roller body with a vibration drive, a stimulation shaft with an imbalance weight with an imbalance cylinder and piston and an adjustment device controling hydraulic liquid with a control cylinder and piston with a volume communicating with the imbalance cylinder and connected to a hydraulic oil source for replacing leakage oil via a controled valve. The valve shuts off with the imbalance piston in its central position. The device has at least one roller body with a vibration drive, a stimulation shaft (14) with an imbalance weight with an imbalance cylinder and hydraulic imbalance piston (17) and an adjustment device controling hydraulic liquid with a control cylinder (34a) and piston with a volume communicating with the imbalance cylinder and connected to a hydraulic oil source for replacing leakage oil via a controlable valve (33). The valve shuts off with the imbalance piston in its central position, from which the normal vibration amplitude can be increased or decreased.
