Abstract
PURPOSE: To obtain an adequate position of setting a throttle valve to its opening degree at idling operation of an engine always corresponding to its operational state, by engageably arranging a diaphragm device, used for a dush pot operated and not operated in accordance with operational conditions of the engine, to the throttle valve.
CONSTITUTION: To a throttle valve 12 arranged in an intake air line 1, an opening degree O at normal idling operation, opening degree OU at idling speed increased for auxiliary equipments driving, touch opening degree OT slightly larger than that opening OU and an opening degree OR at travelling operation are set. A rod 21 fixed to a diaphragm 22 in a diaphragm device 2 can be engaged to a throttle valve lever 13 to decide its opening position. To a negative pressure chamber 24 in the device 2 the negative pressure of intake air in the vicinity of a place at the touch opening degree OT is introduced through a negative pressure line 3 and an atmospheric air line 4 can be also communicated through a solenoid on-off valve 5. Then the on-off valve 5 is open-close operated by an arithmetic unit 6, to which each signal of the negative pressure of intake air, temperature, rotary speed and auxiliary equipments driving in an engine E is input, allowing the throttle valve 12 at that place of opening to perform a dush pot action.
