Abstract:
A hydraulic control unit for a motor-vehicle braking system, witha pump delivering hydraulic fluid under pressure, said pump being capable of being controlled by an electronic control unit (ECU) and supplying the hydraulic fluid for at least one braking device which is coupled to a wheel of the vehicle, a first reservoir for pressureless hydraulic fluid, which is assigned to the pump on the input side, a second reservoir for hydraulic fluid under pressure, which is assigned to the pump on the output side, wherein the pump, the first reservoir and the second reservoir are arranged in a common casing integrated as an electrohydraulic modular unit, and the second reservoir is a hydraulic pressure accumulator, into which the hydraulic fluid is capable of being conveyed by the pump contrary to the force of a spring arrangement, whereby at least a first part of the spring arrangement is formed by a corrugated bellows.
