Abstract

See full text

A hydraulic unit for a braking system of 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. A damper is positioned in the body for damping pressure pulsations in the hydraulic fluid. The damper is selectively operable in a first state having a first damping characteristic, and in a second state having a second damping characteristic different from the first damping characteristic.
