(9) Gas ValvePiston (3) moves up and down inside the bore of cylinder (1). Nitrogen gas charge (2) has a pre-charge of approximately 6205 310 kPa (900 45 psi). Each accumulator is charged with dry nitrogen through gas valve (9).Oil enters pressure oil chamber from the brake pump. The oil reaches the pressure oil chamber through hydraulic outlet (5). The oil pushes piston (3) upward. The pressure of the oil compresses the nitrogen gas.When the pressure in the accumulator reaches approximately 27579 kPa (4000 psi), the supply of oil is stopped. When either brake pedal is pushed, pressurized out flows through hydraulic outlet (5) to the service brake control valve. This action applies the service brakes.
