Understanding the Function of Accumulators

Accumulators come in a variety of forms and have important functions in many hydraulic circuits. They are used to store or absorb hydraulic energy. When storing energy, they receive pressurized hydraulic fluid for later use. Sometimes accumulator flow is added to pump flow to speed up a process. Other times the stored energy is kept []

3) A balance system is fluid pressure applied to a reaction area on the valve to work against spring force and begin to move the valve into its regulating position.This is often regulated line pressure directed through an orifice to the balance spool. As the balance circuit is charged, a feed passage is opened to provide fluid flow to the torque converter and —
