Abstract

A hydraulic block of a slip control system of a hydraulic vehicle brake system has receptacles for inlet valves and outlet valves of the slip control system arranged on a cover side, and receptacles for block valves, intake valves, and hydraulic accumulator on an opposite main side. All connecting bores for wheel brakes and a main brake cylinder are arranged on a transverse side and an eccentric chamber is arranged on an opposite transverse side of the hydraulic block.

First claim

The invention claimed is:

1. A hydraulic block for a hydraulic unit of a slip control system of a hydraulic vehicle brake system, comprising:
a first valve side in which a plurality of outlet valve receptacles configured to receive outlet valves and a plurality of inlet valve receptacles configured to receive inlet valves are defined;
a second valve side opposite the first side and in which a plurality of isolating valve receptacles configured to receive isolating valves, a plurality of suction valves configured to receive suction valves, and at least one accumulator receptacle configured to receive a hydraulic accumulator are defined;
two pump sides in which pump bores configured to receive hydraulic pumps are defined, the two pump sides arranged opposite one another and adjoining the first valve side; and
a connecting side in which wheel brake connecting bores configured to connect to wheel brakes and master cylinder connecting bores configured to connect to a brake master cylinder are defined, the connecting side adjoining the first valve side and the two pump sides.

2. The hydraulic block as claimed in claim 1 , wherein the plurality of inlet valve receptacles, the plurality of outlet valve receptacles, the plurality of isolation valve receptacles, and/or the plurality of suction valve receptacles are arranged in a parallel row that is parallel to an edge of the first or the second valve side.

3. The hydraulic block as claimed in claim 1 , wherein the plurality of inlet valve receptacles comprises four inlet valve receptacles and/or the plurality of outlet valve receptacles comprises four outlet valve receptacles and/or the plurality of isolating valve receptacles comprises two isolating valve receptacles and/or the plurality of suction valve receptacles comprises two suction valve receptacles defined in the second valve side.

4. The hydraulic block as claimed in claim 1 , further comprising:
a motor side in which an eccentric chamber configured to receive a pump eccentric for driving a the hydraulic pump is defined, the motor side adjoining the first and second valve sides.

5. The hydraulic block as claimed in claim 1 , further comprising:
at least one sensor receptacle configured for a pressure sensor defined in at least one of the first valve side and the second valve side.

6. The hydraulic block as claimed in claim 1 , wherein at least one of the pump bores is arranged in the hydraulic block obliquely relative to the first and second valve sides.

7. The hydraulic pump as claimed in claim 1 , wherein all of the wheel brake connecting bores are defined in the connecting side.

8. A hydraulic block for a hydraulic unit of a slip control system of a hydraulic vehicle brake system, comprising:
a plurality of receptacles for valves in a first valve side and in an opposite second valve side;
a first pair of pump bores configured for receiving hydraulic pumps in a first pump side adjoining the first and the second valve side;
a second pair of pump bores configured for receiving hydraulic pumps in a second pump side located opposite the first pump side; and
a third pair of pump bores configured for receiving hydraulic pumps obliquely relative to the first and relative to the second pump side.
