Accumulator pressure speed

The addition of this throttle-sensitive, 1-2 accumulator pressure helps to better control the shift feel based upon the speed of the vehicle. So, a higher speed will result in greater back pressure to the accumulator piston, which will result in a firmer and quicker 1-2. Most accumulators used within industry are limited to an operating pressure of 3000 psi. Hydraulic accumulators store hydraulic fluid under pressure to supplement pump flow and reduce pump capacity requirements, maintain pressure and minimize pressure fluctuations in closed systems absorb shocks, and provide auxiliary hydraulic power in an emergency. Other times the stored energy is kept in reserve until it is needed and may be independent of pump flow. Minimum working pressure P 1 and maximum pressure P 2, the value of P 2 must be lower or equal to the maximum authorized working pressure of the accumulator to be chosen for safety reasons.
