PURPOSE:To make an output shaft turn to a direct-axis construction, by performing the motion of rotation in an external gear member with a driving pin and a driving disk in combination. CONSTITUTION:Each of driving disks 18 is fitted in an output shaft 12 by means of splining, and each of cylindrical bores 20 is formed at regular intervals on the specified radius centering on a center axis 9 of the output shaft 12. Each of driving pins 19 is locked on the center of an external gear member 8, that is, the specified radius centering on an eccentric axis 10 in a way of slidingly contacting the inner circumferential surface of each cylindrical bore 20 of these driving disks 18. A high pressure fluid is fed from an inflow port 22 to a one side chamber partitioned between an internal gear member 7 and the external gear member 8 in a jet rotor section 4, then discharged out of the other side chamber via a discharge port 23. The one side chamber situated at the eccentric side of the external gear member 8 expands the capacity while the other side chamber contracts it the other way and consequently the external gear member 8 revolves clockwise by rotation, for example, round counterclockwise. Revolution of this external gear member 8 is not transmitted to each driving disk 18 and on the other hand, the motion of rotation in the external gear member 8 causes these driving disks 18 to be solidly turned as one body so that the output shaft 12 turns too. |
