<P>PROBLEM TO BE SOLVED: To provide a waste heat regeneration system capable of preventing a working fluid from flowing outside a rankine cycle circuit without interfering with the driving of a motor which is a drive source of a pump. <P>SOLUTION: In the waste heat regeneration system 100, a gear pump 111 and an electric motor 117 have a drive shaft 121 in common. The inside 111a of the pump and the inside 117a of the motor are demarcated by a shaft seal 122, and the inside 111a of the pump forms a part of a circulation passage 115 of the rankine cycle circuit 110. To a lower part 116a of a housing 116, one end of a communication passage 127 communicated with the inside 117a of the motor is connected, and the other end of the communication passage 127 is connected to the circulation passage 115 between an expander 113 and a condenser 114 in the rankine cycle circuit 110. <P>COPYRIGHT: (C)2013,JPO&INPIT |
