Abstract
The invention relates to a controller for an unbalanced mass adjusting unit in a vibration exciter. Said controller comprises an adjusting piston for changing the relative position of unbalanced masses in the vibration exciter that is coupled to a reference piston. The position of a piston rod of the reference piston is detected by a pressure sensor and is furnished to a controller in the form of a position signal. The controller compares the position signal with an operating signal given by an operator and generates a control signal with which the position of a selector valve that controls the oil supply to or the oil discharge from the reference piston can be changed.
