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 1):
A heat recovery system having a working fluid circuit ( 1 ), the heat recovery system comprising a first heat exchanger ( 2 a ) connected in an exhaust gas line ( 3 ) of an internal combustion engine ( 5 ) and a second heat exchanger ( 2 b ) inserted into a line, wherein the first and second heat exchangers ( 2 a ,  2 b ) are part of the working fluid circuit ( 1 ), wherein the working fluid circuit also has at least an expansion machine ( 11 ), a condenser ( 12 ) and first and second fluid pumps ( 15 a ,  15 b ), and wherein the first and second heat exchangers ( 2 a ,  2 b ) are respectively connected to the first and second fluid pumps ( 15 a ,  15 b ).
