PROBLEM TO BE SOLVED: To save a constitution element so as to obtain a high reliability by connecting a control device to both part systems of a hydraulic part system and an electric part system, carrying out suitable sitting or switching of an operating mode switching element formed integrally with both part systems respectively. SOLUTION: An output conversion system comprises a hydraulic part system and an electric part system 13 which are connected to each other through a shaft 14. Mechanical elements rotatably supported of a hydraulic machine 15 and an electric machine 20 of those part systems 12, 13, are connected to the shaft 14 and the like so as to regulate efficiency of both part systems 12, 13 differentially at the time of a rated output. Both part systems 12, 13 are monitored by a control device 26, and a pipe passage compound body or an electric compound body are embodied. A suitable setting or switching of first and second operating mode switching elements integrated with both part systems 12, 13 is carried out, one of bidirectional functions in both part systems 12, 13 is operated, and thereby, a constituting element is saved so as to obtain a high reliability. |
