Abstract: A heat exchanger arrangement is provided for an internal-combustion engine having a heat engine, which converts hot steam of a working medium by way of an expansion device to kinetic energy. The working medium, that can be delivered by a pump, can be heated in a first heat exchanger by a coolant and in a second heat exchanger by an exhaust gas of the internal-combustion engine. In the delivery direction, the working medium first flows through the first heat exchanger and, subsequently, through the second heat exchanger. The exhaust gas can flow through the first heat exchanger.

The working medium, that can be delivered by a pump, can be heated in a first heat exchanger by a coolant and in a second heat exchanger by an exhaust gas of the internal-combustion engine. In the delivery direction, the working medium first flows through the first heat exchanger and, subsequently, through the second heat exchanger. The exhaust gas can flow through the first heat exchanger. A very high efficiency can be achieved for the internal-combustion engine with the above-described heat engine.

Abstract: An assembly comprises a tubular shaft that has a first axial end and a second axial end. A tubular pump is housed within the shaft and is driven by an electric motor. A lid is detachably connected to the first axial end of the shaft. At least one line is connected to the electric motor. The tubular shaft has an opening adjacent to the first axial end. A u-shaped frame is disposed within the opening such that an open part of the frame faces the first axial end. The at least one line is disposed within the frame to form a fluid tight seal about the first end and the at least one line.
