Dashpot: Description and Operation

Dashpot:

Dashpot:

The dashpot consists of a diaphragm chamber with a small orifice open to the atmosphere, and a light spring. When the throttle is open, the light spring pressure extends the dashpot. When the throttle closes, it first comes to rest on the dashpot, which lets the throttle close slowly the rest of the way as air is forced out of the chamber through the orifice.
