Dashpot: Description and Operation

Dashpot:

PURPOSE
The Dashpot allows the throttle plate to gradually close during deceleration. This prevents hesitation during the transition from deceleration to sudden acceleration, and prevents engine stalling on sudden deceleration.

OPERATION
the Dashpot is attached to the throttle Body. A tab on the throttle shaft contacts the Dashpot. When the throttle is pressed on and then released, the relese action is slowed by means of a spring and diaphragm, wich make up the dashpoallowing it to collapse at a controlled rate, to prevent sudden throttle closing.
