摘要:
A device for actuating a butterfly throttle valve of an internal combustion engine includes a hydraulic setting member for rotating a shaft of the throttle valve. The hydraulic setting member is driven by a branch flow of fuel delivered by a fuel pump and acting as pressure medium. The branch flow passes through a series of connection of adjustable throttles connected in a hydraulic bridge circuit. The throttles are adjusted by a regulating signal corresponding to the difference between an actual position signal delivered by a position sensor coupled to the throttle valve, and a desired position sensor coupled for example to a gas pedal of the motor vehicle.
