Hydraulic unit for anti-slip braking systems

1. 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 of said accommodating bores for the accommodation of feeding devices of a pump extends transversely to the first and the second valve row, and

wherein second and third accommodating bores for the accommodation of second and third feeding devices of a pump extend transversely to the third valve row.

2. The hydraulic unit as claimed in claim 1 , wherein

the accommodating bores for feeding devices are arranged at an angle (α) relative to each other.

3. The hydraulic unit as claimed in claim 1 comprising accommodating bores for feeding devices that are arranged at an angle (α) relative to each other, wherein

the angle (α) between respectively adjacent accommodating bores is identical and amounts to 120°.

4. The hydraulic unit as claimed in claim 1 , wherein

a row of pressure sensor accommodating bores are provided being arranged beside the third valve row.

5. A hydraulic unit for slip-controlled brake systems,

including an accommodating member which accommodates inlet and outlet valves in several valve accommodating bores of the first and the second valve row,

including further valve accommodating bores arranged in the 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,

a first of said accommodating bores for the accommodation of feeding devices of a pump extends transversely to the first and the second valve row, and

a second and a third of said accommodating bores for the accommodation of feeding devices of a pump extend transversely to the third valve row,

the first, second and third of said accommodating bores for feeding devices are arranged at an angle (α) relative to each other wherein

an accumulator accommodating bore is provided in parallel to the axis of the first accommodating bore for the feeding device, and in that the accumulator accommodating bore and the first accommodating bore are arranged at a frontal end of the accommodating member.

6. The hydraulic unit as claimed in claim 5 , wherein the accumulator accommodating bore is passed through between adjacent valve accommodating bores and at right angles relative to the first and second valve rows.

7. A hydraulic unit for slip-controlled brake systems, including a first, second and third valve row, wherein each of said valve rows comprises a plurality of valve accommodating bores,

including an accommodating member which accommodates inlet and outlet valves in several valve accommodating bores of the first and a the second valve row,

including further valve accommodating bores arranged in the 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,

a first of said accommodating bores for feeding devices of a pump extends transversely to the first and the second valve row, and

second and third accommodating bores for the accommodation of second and third feeding devices of a pump extend transversely to the third valve row, wherein

a non-return valve accommodating bore opens into each accommodating bore for a feeding device, and in that the non-return valve accommodating bore is arranged in parallel to the axis of the pump accommodating bore.

8. The hydraulic unit as claimed in claim 7 , wherein

a through-bore is provided between the second and the third accommodating bore and the through-bore serves as a passage for an electric line.

9. The hydraulic unit as claimed in claim 1 , wherein

a collecting duct connects a pressure side of the feeding devices to the high-pressure accumulator.
