Abstract

PURPOSE: A deceleration control system having driveability and exhaust gas emission control together, by changing operating time of dash pot in accordance with throttle opening at the vehicle reducing the speed.
CONSTITUTION: When an accelerator pedal is depressed deeply, a throttle valve 2 is rotated largely, its edge is positioned downward more than the negative pressure port 15. A dash pot lever 4 is rotated counter-clockwise, as the negative pressure does not operate to the negative pressure chamber 11d of acruator 11, the rod 12 is pushed leftward to rotate the dash pot guide 5 counter-clockwise. With an accelerator pedal released, on this condition, the throttle valve 2 is rotated clockwise, however when it is rotated to the position B, the lever 4 contacts with the rod 9 to push it, subsequently reaches position A, the negative pressure is led into above negative pressure chamber 11d gradually, throttle valve 2 is rotated gradually to shutting direction by turning the guide 5 clockwise.
