TWO-SPEED GOVERNOR OF COMBUSTION ENGINE ROTATIONAL FREQUENCY

摘要

A two-speed governor of combustion engine rotational frequency comprises: a double-crank arm that by one side through intermediate lever is pivotally connected to a fuel injection pump rack, the other side of intermediate lever is pivotally connected to movable coupling that kinematically connected to spring; a lever for engine control; screws for maximal and minimal fuel supply. The other end of the double-crank arm is pivotally connected to slave lever of electromechanical actuating device that has control circuit with back coupling by position of the slave lever. The movable coupling is connected to electric magnet that switches off the fuel supply irrespectively of position of the slave lever in case of absence of current in network, electronic control block and in case of emergency.
