Abstract

PURPOSE:To prevent overload of an engine at a high speed for better operability by lowering a difference between a main engine output indication signal value and the set signal value by the steering wheel in the pitch setting signal below the indication signal equivalent to the maximum output of the main engine at a desired ratio. CONSTITUTION:In setting the high speed, when the steering wheel is positioned within a desired set range, a switch 6 is actuated to feed an indication pressure of the main engine output to an A port of a reducing valve B through valves 14 and 15. With the closing of a differential pressure switch from a previously set pressure to the newly set pressure, a motor is driven to feed air pressure to a B port via a valve 14 through a cam 27 being compared with the set pressure from a valve 9 with a switch 24 or 25. When the switch 24 or 25 is opened, the valve 14 is opened to stop the motor and a set pressure equal to the air pressure of the valve 23 is fed to the B port from the valve 9. Change in the opening of a valve 13a corresponding to this varies the pressure of an E port. This pressure change is transmitted to a C port via an integrating element 30 to actuate a variable pitch propeller driving mechanism for greater pitch while being compared with the maximum indication pressure of the main engine output of a D port.
