An anti-lock braking hydraulic unit for a vehicle includes a body with actuator-side and brake-side ports. Inlet and outlet valves are positioned in the body and operable to selectively supply and relieve hydraulic fluid to/from the wheel cylinder of a brake via the brake-side port. An accumulator is fluidly coupled with the outlet valve to receive hydraulic fluid relieved from the wheel cylinder. The accumulator includes a bore formed in the body and an orifice formed in the body in fluid communication with the bore. The orifice is positioned at a first end of the bore, and a closure is sealingly engaged with a second end. A piston is sealingly received in the bore, movable within the bore along an axis defined thereby and dividing the bore into first and second variable volume chambers. At least one ferromagnetic pair magnetically biases the piston toward the first end of the bore. |
