PURPOSE: A hydraulic unit is provided to reduce noise and pulsation of pressure from a pump by using a damping unit, and to cut down cost by securely sealing the inlet of the damping unit in assembling the pump without additional sealing materials. CONSTITUTION: A hydraulic unit for a brake system electronically controlled of a vehicle is composed of a housing block(10), and the housing block is composed of an installation surface(12) for the electronic control unit, a hydraulic connection space supplying pressure media to the hydraulic unit, an installation space(24) for a pump(50) and a damping unit(22). The damping unit is arranged in the lower part of the pump to damp pulsation of pressure and to regulate brake pressure of a wheel brake cylinder. The installation space of the damping unit and the installation space of the valve are extended to the installation surface of the housing block, and the damping unit is protruded on the installation surface.
