Abstract

The invention relates to a prime mover arrangement comprising an internal combustion engine (1) for driving a first shaft (2) and comprising a steam engine (4), which is connected to the first shaft by means of a clutch arrangement (3), for driving a second shaft (5). Furthermore, a freewheel (6) which interacts with the clutch arrangement (3) is arranged between the first shaft (2) and the second shaft (5) in order to transmit a rotational movement of the second shaft (5) to the first shaft (2) in a first operating mode and to allow the first shaft (2) to freewheel relative to the second shaft (5) in a second operating mode. The clutch arrangement (3) is designed as a fluid-actuated clutch arrangement (3) which can be operated with positive pressure or negative pressure and bridges the freewheel (6) in a friction-fitted or form-fitted manner in order to transmit the rotational movement of the internal combustion engine (1) to the second shaft (5) via a flange (7) arranged on the first shaft (2).
