Patent ID: 7018003

Claim:
Hydraulic unit for slip-controlled brake systems, comprising: an accommodating member having a first housing surface, a second housing surface angled relative to the first housing surface, and a third housing surface opposite to the second housing surface; a first row of inlet valve-accommodating bores that open into the first housing surface; a second row of outlet valve-accommodating bores that open into the first housing surface; at least one braking pressure generator port that opens into the second housing surface; at least one wheel brake port that opens into the second housing surface; a pump-accommodating bore arranged in the accommodating member and extending transversely to the inlet and outlet valve-accommodating bores, generally parallel to and between the first and second rows of valve-accommodating bores; a motor-accommodating bore arranged in the accommodating member and directed to the pump-accommodating bore; an accumulator-accommodating bore that opens into the third housing surface and extends transversely to the inlet and outlet valve-accommodating bores with the second row of valve-accommodating bores positioned between the accumulator-accommodating bore and the pump-accommodating bore; a third row of valve-accommodating bores arranged in the accommodating member between the first row of valve-accommodating bores and the second housing surface, the third row of valve-accommodating bores including an electric change-over valve-accommodating bore which is hydraulically linked to the pump-accommodating bore by way of a portion of a suction channel that traverses the first row of valve-accommodating bores; and a plurality of channels interconnecting the valve-, pump- and accumulator-accommodating bores and the at least one braking pressure generator port and the at least one wheel brake port to provide a hydraulic connection between the at least one braking pressure generator port and the at least one wheel brake port.
