Accumulators are special speed shifting conversion units which determine shifting time and its quality. The use of hydraulic accumulators makes it possible to ensure faultless gear change in automatic transmissions with relatively low delays in response of the gearshift valves. Accumulators play the role of so-called shock-absorbers and allow controlling actuation speed of servo drives thanks to gradual pumping of ATF from one intermediate chamber to another.
