POA. The function of the Accumulator Charging Valve is to control the charging of the accumulator within a preset switching range. There are integrations of a pilot stage with defined hysteresis, a main piston, and a check valve into the circuit. Therefore, the charge of the accumulator happens at port A from pump port P across the check valve.
