Modifier Accumulator: Operation
- The accumulator piston is pushed to the right by spring force. Conversely, pressure modifier pressure is applied to the right side of the piston and pushes the piston to the left side. The accumulator piston is maintained by the balance of pressure modifier pressure and spring force. The piston moves to the left when the pressure modifier pressure becomes high and absorbs the pressure. Conversely, when the pressure becomes low, the piston moves to the right and compensates for the pressure insufficiency.
