PROBLEM TO BE SOLVED: To provide an electronic hydraulic governor which is compact in size.SOLUTION: An electronic hydraulic governor 1 comprises: a gear pump 7 having a power piston 11, an input shaft 3, a drive gear 5 and a driven gear 6 bitten to the drive gear 5, and pressure-sending working oil; a control valve having a valve bushing 8 fixed to the driven gear 6 of the gear pump 7 and a spool 9 inserted into the valve bushing 8, and switching an oil passage of the working oil to the power piston 11 according to a slide of the spool 9; an actuator 10 which is electronically driven for sliding the spool 9; and a speed sensor 16 for detecting the number of revolutions of the valve bushing 8. A sensor gear 15 being an object to be sensed by the speed sensor 16 is arranged at the valve bushing 8. |
