PROBLEM TO BE SOLVED: To increase the discharge flow amount of a pump without increasing the size of the pump. SOLUTION: A drive shaft 5 connected to the output shaft of an engine and pump shafts 3A, 3B for driving pump bodies 4A, 4B are connected to each other via a driving gear 6 fixed to the drive shaft 5 and driven shafts 7A, 7B fixed to the pump shafts 3A, 3B for meshing with the driving gear 6 and each having a less number of teeth than the driving gear 6. Thus, the rotating speed of the pump shafts 3A, 3B are higher than the rotating speed of the drive shaft 5. COPYRIGHT: (C)2006,JPO&NCIPI |
