Hydraulic unit for anti-slip braking systems

A hydraulic unit for slip-controlled brake systems,

• including an accommodating member which accommodates inlet and outlet valves in several valve accommodating bores of a first and a second valve row,
• including further valve accommodating bores arranged in a third valve row spaced from the first and the second valve row,
• including a pump accommodating bore arranged between the second and the third valve row for the accommodation of at least one pump driving element, and accommodating bores for the accommodation of feeding devices of a pump, and
• including several pressure fluid channels that connect the valves, a high-pressure accumulator and wheel brakes, and are able to establish a hydraulic connection between the high-pressure accumulator and the wheel brakes or a braking pressure generator and the wheel brakes, wherein
• a first accommodating bore for a first feeding device of the pump is passed through between valve accommodating bores of the first and the second valve row, and
• wherein second and third accommodating bores for the accommodation of second and third feeding devices of the pump are passed through between valve accommodating bores of the third valve row.
