Abstract

PURPOSE: A deceleration control system of vehicle having emission control and driveability together, constructing to obtain returning characteristics corresponded to the throttle valve opening in the case of reducing the speed.
CONSTITUTION: When a throttle valve 18 opening is larger more than position C with an accelerator pedal depressed deeply, the negative pressure produce appreciably in port 19, the second diaphragm 4 is pushed by a spring 14, a flange 13b of vent member 13 is contacted with the stopper 10b. Furthermore the first diaphragm 3 projects leftward with the rod 11 by a spring 12, the valve 11a is off from the seat 13a. With reducing the speed from this condition, the rod 11 is pushed by returning and rotating dash pot lever 21, the rod 11 is pushed at this moment, returning speed of throttle valve 18 is reduced due to operation characteristics of the first diaphragm 3. After the rod 11 has been contacted with the vent member 13, since the negative pressure produced in the port 19 operates to the negative pressure chamber 7 through the throttle 15, returning motion is stopped for a moment.
