<P>PROBLEM TO BE SOLVED: To improve efficiency in cooling a rotary electric machine used in a waste heat utilization system, and to improve the efficiency of waste heat recovery. <P>SOLUTION: A rankine cycle circuit comprises an expander 72, a condenser, a gear pump 67 and a boiler. A discharge passage 47 is connected to the discharge chamber of a pump chamber 64. A branch passage 48 is branched and connected to the discharge passage 47, and a throttle passage 49 is formed at the terminal end of the branch passage 48. The throttle passage 49 is opened in an internal space K in a motor housing 37. An expansion part 44 is formed while being expanded on the bottom of a peripheral wall 372 of the motor housing 37, and a storage space 68 is formed while being recessed at the inside of the expansion part 44. A part of an upper opening of the storage space 68 is covered with the outer peripheral surface of a stator 42, and the storage space 68 is made to communicate with the internal space K. <P>COPYRIGHT: (C)2013,JPO&INPIT |
