Abstract: A braking system includes an accumulator positioned along the brake line between the wheel brake and a pump. The accumulator includes a cylinder defining a bore and a piston fitted within the bore. The cylinder defines an inlet and an outlet fluidically connecting the bore to the brake line. The outlet is axially spaced from the inlet and is positioned to be sealed closed by the piston when it is proximate to inlet. The accumulator stores a reserved volume of fluid that is not delivered to the pump via the outlet to thereby reduce the volume of fluid delivered to the master cylinder by the pump and prevent damage to the lip seals during ABS control.
