Abstract: A foil bearing (10) having at least one foil (16, 18), which is arranged and fixed in place inside a bearing bushing (12). In order to simplify the production, in particular assembly, of the foil bearing (10), the bearing bushing (12) has at least two openings (20, 22, 24) offset from each other in the circumferential direction of the bearing bushing (12) or depressions (120, 122, 124) made in the inner lateral surface of the bearing bushing, into which openings or depressions two opposing circumferential end sections (16 a, 16 b, 18 a, 18 b) of the at least one foil (16, 18) engage.

Abstract: A foil bearing (10) having at least one foil (16, 18) which is arranged and fixed in place inside a bearing bore (14) of a bearing support (12). The bearing support (12) is made of aluminum or an aluminum alloy, and the surface of the bearing bore (14) is provided at least in one contact region (20) of the at least one foil (16, 18) with a hard material layer (26). The bearing support (12) can be produced in a simple and cost-effective manner, has a low weight and a good thermal conductivity.

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, means which interact with the clutch arrangement (3) are 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 a freewheel between the first shaft (2) and the second shaft (5) in a second operating mode. The clutch arrangement (3) can be operated with positive pressure or negative pressure. Furthermore, the clutch arrangement (3) can be shifted by a fluid, and a torque transmission is provided between the first shaft (2) and the second shaft (5).
