A vibration exciter, particularly for a vibration pile driver, has an exciter transmission having at least two imbalance masses, which are attached on one or on multiple shafts, and a pivot motor for adjusting the relative rotational position of the imbalance masses relative to one another. A pump for supplying the pivot motor is provided, which pump is operated by way of a shaft of the exciter transmission.
