弁の戻シネ足につながる不具合を生じる。When supplying a mixture of fuel and air or only air to an internal combustion engine, conventionally, a spring force was used to close a throttle valve provided in the middle of the intake system, as disclosed in Japanese Patent Application Laid-Open No. 154141/1983. However, the wider the opening of the throttle valve, the greater the closing torque.The actuator for adjusting the opening of the throttle valve must be made larger, and the direction of closing the throttle valve is increased. If the spring force is reduced, a problem will occur that will lead to the throttle valve returning to its original position.

The valve 2 indicates an actuator that adjusts the opening degree of the throttle valve 1, and the actuator 2 adjusts the opening degree of the throttle valve l according to a command from the controller 3 via a link mechanism. 4 is a diaphragm. 4af: Equipped with an actuator for closing the throttle valve,
One chamber 5 partitioned by a diaphragm 4a is configured to communicate with a valve box 7C of a solenoid pulp 7, which will be described later, via a fluid passage 12. Further, the pulp box 7C has a fluid passage 13F, which is branched from the fluid passage 12. Intermediate - Upstream side 1 of C-shaped valve 1
It is configured to communicate with 4. On the other hand, the chamber 6 of the actuator 4 dedicated to closing the throttle valve is configured to selectively communicate with the seat hole IO of the valve 7a or the seat hole 11 of the valve 7b via the fluid passage 8 or 9 of the solenoid pulp 7. . Solenoid pulp 7 is
Like the throttle valve opening adjustment actuator 2, it receives a command from the controller 3, and the solenoid pulp 7 is turned on when the throttle valve opening adjustment actuator 2 is activated to open the pulp 7a. Therefore, pulp 7
a) The upstream side 14 of the throttle valve 1 and the chamber 5.6 of the actuator 4 communicate via the hole 10. Further, when the input from the controller 3 to the throttle valve opening adjustment actuator 2 becomes zero, the solenoid pulp 7 is turned off to close the valve 7af, and the pulp 7be is opened to allow the seat hole 11 of the pulp 7b to be closed by the fluid. It communicates with the downstream side 1b of the throttle valve 1 via a passage 15.

態で追従する。In the above configuration, the throttle valve 1 is normally adjusted in rotation only by the actuator 2, which is controlled by commands from the controller 3, and when the engine is stopped, the input from the controller 3 to the actuator 2 is set to zero. When this occurs, the actuator 2 becomes free. When activated, it turns on and opens the pulp 7a. Therefore, since the upstream side 14 of the throttle valve 1 and the chamber 5.6 of the actuator 4 communicate through the seat hole 10 of the pulp 7a, the pressure in the chamber 5.6 is kept at the same pressure, and the diaphragm 4a The operation of the throttle valve 1 is followed in a free state.

従する。Therefore, the inside of the chamber 6 of the actuator 4 dedicated to closing the throttle valve 1 passes through the fluid passages 9 and 15 to the F of the throttle valve 1.
The pressure in the chamber 5 is maintained at the same pressure as the upstream side 14 of the throttle valve 1, and the diaphragm 4a maintains the same pressure as the upstream side 16 of the throttle valve 1. It is pulled toward the chamber 6 side by the difference in pressure and closes the throttle valve 1. At this time, the throttle valve opening adjustment actuator 2 is in a free state, so it follows the closing operation of the throttle valve 1. do.
