不能時の安全機構。[Claims for Utility Model Registration] (1) The control circuit is controlled to open and close between a fully closed position and a fully open position by an actuator operated by a signal outputted by inputting and calculating at least an accelerator operation signal. An intake passage 1 equipped with a first throttle valve 3 has a fully closed state when the first throttle valve 3 becomes uncontrollable due to a failure of the control circuit or a sensor that supplies a signal to the control circuit. A second throttle valve 6 is disposed, the second throttle valve 6 is biased in the closing direction by a spring 9, and when the first throttle valve 3 is normally controlled, the second throttle valve 6 is A rotating lever 8 that rotates together with the throttle valve 6 is locked in the fully open position of the second throttle valve 6 by a locking lever 11 that is pivotally fixed to the housing 2 that forms the intake passage 1. and when the first throttle valve 3 becomes uncontrollable due to a failure of the control circuit or the sensor and rotates beyond the fully open position, the first throttle valve 3 rotates integrally with the first throttle valve 3. The locking lever 11 is rotated by the lever 5, and the locking of the rotary lever 8, which rotates together with the second throttle valve 6, is released, and the second throttle valve 6 is closed. A safety mechanism that can prevent the throttle valve from being controlled. (2) When the first throttle valve 3 rotates beyond the fully open position, the rotation of the rotary lever 5, which rotates together with the first throttle valve 3, is transmitted through the link lever 15 to the A safety mechanism for when the throttle valve cannot be controlled according to claim (1) of the above-mentioned utility model registration, which rotates the locking lever 11. (3) When the first throttle valve 3 rotates beyond the fully open position, the electric contacts are opened and closed by the rotation of the rotary lever 5 that rotates together with the first throttle valve 3;
The safety mechanism for when the throttle valve cannot be controlled according to claim (1), which operates the solenoid actuator 23 to rotate the locking lever 11. (4) Pistons 26 and 28 that are slidable within the cylinders 25 and 27 are arranged close to each of the rotary lever 5 that rotates together with the first throttle valve 3 and the locking lever 11. , the respective cylinders 25 and 27 are connected by a fluid passage 29, and when the first throttle valve 3 rotates beyond the fully open position, the locking lever 11 is rotated through movement of fluid. A safety mechanism when a throttle valve becomes uncontrollable as described in claim (1) of the utility model registration.
