Stage: PROBLEM TO BE SOLVED: To provide a device and a method for generating oscillations which can be used particularly efficiently, in particular for a construction machine.SOLUTION: A device for generating oscillations for a construction machine, comprises: a housing; a piston which is movable back and forth between a first return point and a second return point; a pressurized fluid supply unit capable of generating oscillations by feeding/discharging a pressurized fluid into/from a working chamber, respectively through at least one actuatable control valve so as to cause the piston to make a reciprocating motion; and a control unit which is configured to actuate the at least one control valve and by means of which the motion of the piston in the working chamber is controllable and adjustable. According to the invention, the control unit is configured to control the piston in a first operating mode for generating oscillations and in a second operating mode for generating impact pulses, wherein a strike surface is formed on at least one end side of the working chamber, which surface the piston strikes when it reaches at least one of the two return points, thereby, enabling an impact pulse to be generated.SELECTED DRAWING: Figure 1 (Grant)
