Abstract (en)

[origin: WO2014166608A1] The invention relates to a vibrating ram arrangement comprising a hydraulic assembly (1), a vibrator (2) which is connected to the hydraulic assembly (1) via hydraulic tubes (3), and a controller (S) which is paired with the hydraulic assembly (1). The hydraulic assembly (1) has a hydraulic pump (6) which is driven by an internal combustion engine (5), and the vibrator (2) has imbalances (11) and an adjustable hydraulic engine (2) for driving the imbalances (11). A hydraulic fluid is conducted through the hydraulic assembly (1), the hydraulic tubes (3), and the hydraulic engine (10) in a circuit. A frequency sensor (14) for determining the frequency of the vibrator (2) is connected to the controller (S), and the controller (S) is designed to control a volumetric flow rate conducted through the circuit dependent on the signal of the frequency sensor (14). According to the invention, the vibrator (2) has a device (12), which is independent of the controller (S), for automatically adjusting a displacement volume of the hydraulic engine (10) dependent on a pressure within the circuit.
