Abstract:
The invention relates to a waste heat recovery system having a working fluid circuit ( 1 ) for an internal combustion engine, comprising a first heat exchanger ( 2 a ) connected in an exhaust gas line ( 3 ) of the internal combustion engine ( 5 ) and a second heat exchanger ( 2 b ) inserted into a line, which are part of the working fluid circuit ( 1 ), which has at least an expansion machine ( 11 ), a condenser ( 12 ), and a fluid pump. According to the invention, a waste heat recovery system that is improved in particular in respect of an efficiency of the system is provided. This is achieved in that each of the two heat exchangers ( 2 a,  2 b ) is assigned a fluid pump ( 15 a,  15 b ). Said fluid pumps ( 15 a,  15 b ) are combined in a two-stroke vane cell pump ( 16 ).

Claim (Index 5):
The heat recovery system according to  claim 3 , characterized in that the vane cell pump ( 16 ) is configured to be operated with respect to a delivery quantity distribution into the first displacement chamber ( 24 a ) and into the second displacement chamber ( 24 b ) at a constant or adjustable total delivery quantity.
