Dashpot: Description and Operation

Dashpot

Dashpot

Purpose

The dashpot prevents the throttle from suddenly closing completely and causing an over-rich condition when the accelerator is released. 

Location

located on the throttle body,

Construction

It consists of a diaphragm chamber with a small orifice open to the atmosphere and a light spring. 

Operation

When the throttle is open, spring pressure extends the dashpot. When the throttle closes, it first comes to rest on the dashpot, which lets the throttle
close slowly, as air is forced out of the chamber through the orifice.
