Abstract

PURPOSE: To prevent from run-on permitting the opening of throttle valve to throttle more than an ordinary idling period.
CONSTITUTION: With turning OFF an ignition switch 39, simultaneously permitting the magnetic valve 42 to deenergize. Thus, the main actuation pressure chamber 23a of a negative pressure actuator 20 is communicated to the atmosphere through the atmospheric open port 36. Besides, since in this case the cylinder reaches a high temperature, the heat sensitive change-over valve 42 is actuated by the sensor 45, where the auxiliary actuating pressure chamber 23b is exposed to the atomosphere. Accordingly, both of actuating pressure chambers 23a, 23b produce the atomospheric pressure causing the main and auxiliary diaphragms 22a, 22b to displace in opposite to B direction, the throttle valve 5 is rotated further in opposite to D direction than the normal idling period by actuating the connecting rod 26 and interlocking arm 9 in order to throttle the intake air passage.
