PURPOSE:To decrease overall capacity of an internal-combustion engine, by eliminating the necessity for providing a hydraulic pump only used for a hydraulic pump only used for a hydraulic power souce, that is, by providing a transmission device between plural power sources and output side and using a gear train in the transmission device both for power transmission and gear pump. CONSTITUTION:The first engine 1 is directly connected to an output shaft part 4, while the second engine 2 is connected to the output shaft part 4 through a clutch unit 3. The periphery of a driven gear 26 and driving gears 27, 29, forming the output shaft part 4, is air-tightly enveloped by a case 4, and these gears 26, 27, 29 are utilized to form a gear pump. |
