Abstract:
A hydraulic unit for slip-controlled brake systemswith a housing that contains inlet and discharge valves in several valve-receiving bores in a first and second valve row, with a pump bore arranged outside the two valve rows in the housing, which is oriented transversely to the direction in which the valve-receiving bores open into the housing, with a motor-receiving bore oriented vertically to the pump bore and arranged outside the two valve rows in the housing, with an accumulator-receiving bore opening into the housing outside the two valve rows, with several pressure fluid channels that connect the valves, the pump bore and the accumulator-receiving bore and establish a hydraulic connection between one brake pressure transducer and several wheel brakes, wherein the accumulator-receiving bore is arranged parallel to the axis of the valve-receiving bores of the two valve rows and the motor-receiving bore and that the accumulator-receiving bore and the valve receiving bores of the first and second valve row open next to one another into a first end face of the housing, characterized in that the bore depth of the accumulator-receiving bore has been minimized to such an extent that it can cover the pump bore and that as a result of the minimal bore depth a connecting channel leading to the valve-receiving bore of the second valve row and return flow channel connected to the pump bore lead at an inclined angle relative to the end face of the housing and to the accumulator-receiving bore.
