Abstract

A hydraulic block for a hydraulic assembly of a slip control system for a hydraulic vehicle brake system includes a mount for a brake circuit pressure sensor in a flat side of the hydraulic block. The mount for the brake circuit pressure sensor is configured to measure pressure in at least one brake circuit of the vehicle brake system and communicates with a connecting line through a transverse line and a vertical line. The connecting line connects a mount for a brake pressure build-up valve to a mount for an isolating valve. The hydraulic block further includes a mount for a master brake cylinder pressure sensor and a mount for a brake circuit pressure sensor for each brake circuit.

First claim

The invention claimed is:

1. A hydraulic block for a hydraulic assembly of a slip control system of a hydraulic vehicle brake system, comprising:
a first row of receptacles for brake pressure build-up valves, the first row including a first brake pressure build-up valve receptacle;
a second row of receptacles for brake pressure reducing valves;
a third row of receptacles for isolating valves and intake valves, the third row including a first isolating valve receptacle;
a connecting line that leads from the first isolating valve receptacle to the first brake pressure build-up valve receptacle; and
a receptacle for a brake circuit pressure sensor that is disposed on an opposite side of the third row from the second row and that communicates with the connecting line,
wherein the connecting line is a straight line bored in from an outer surface of the hydraulic block.

2. The hydraulic block according to claim 1 , further comprising:
a vertical line that opens into the connecting line,
wherein, when viewed from direction of a surface in which the receptacles for the brake pressure build-up valves are defined, the connecting line passes behind the first isolating valve receptacle and, at a position that is on the opposite side of the third row from the second row, the vertical line opens into the connecting line in such a way that the receptacle for the brake circuit pressure sensor communicates with the connecting line via the vertical line.

3. The hydraulic block according to claim 2 , further comprising a transverse line that opens into the vertical line, the receptacle for the brake circuit pressure sensor communicating with the connecting line via the transverse line and the vertical line.

4. A hydraulic block for a hydraulic assembly of a slip control system of a hydraulic vehicle brake system, comprising:
a first row of receptacles for brake pressure build-up valves, the first row including a first brake pressure build-up valve receptacle;
a second row of receptacles for brake pressure reducing valves;
a third row of receptacles for isolating valves and intake valves, the third row including a first isolating valve receptacle;
a connecting line that leads from the first isolating valve receptacle to the first brake pressure build-up valve receptacle; and
a receptacle for a brake circuit pressure sensor that is disposed on an opposite side of the third row from the second row and that communicates with the connecting line, wherein:
the hydraulic block defines an eccentric space for an eccentric element configured to drive two hydraulic pumps, the eccentric space disposed in a longitudinal center of the hydraulic block, and
a leakage line leads from the eccentric space to an external side of the hydraulic block.

5. The hydraulic block according to claim 4 , wherein the eccentric space is disposed between the second row of receptacles for the brake pressure build-up valves and the third row of receptacles for the isolating valves and the intake valves.

6. The hydraulic block according to claim 4 , wherein the leakage line runs in the longitudinal center of the hydraulic block.

7. A hydraulic block for a hydraulic assembly of a slip control system of a hydraulic vehicle brake system, comprising:
a first row of receptacles for brake pressure build-up valves, the first row including a first brake pressure build-up valve receptacle;
a second row of receptacles for brake pressure reducing valves;
a third row of receptacles for isolating valves and intake valves, the third row including a first isolating valve receptacle;
a connecting line that leads from the first isolating valve receptacle to the first brake pressure build-up valve receptacle;
a receptacle for a brake circuit pressure sensor that is disposed on an opposite side of the third row from the second row and that communicates with the connecting line;
a connection for a master brake cylinder;
a master brake cylinder line that passes from the connection for the master brake cylinder through between two receptacles for the brake pressure build-up valves and two receptacles for the brake pressure reducing valves to between the first isolating valve receptacle and a first intake valve receptacle of the third row; and
a receptacle for a master brake cylinder pressure sensor between the two receptacles for the brake pressure reducing valves, the first isolating valve receptacle, and the first intake valve receptacle, the receptacle for the master brake cylinder pressure sensor communicating with the master brake cylinder line via a transverse line.
