Abstract

A pump housing has at least two inlet valve openings located in a first row, at least two outlet valve openings located in a subsequent second row, and at least one high-pressure switching valve opening and at least one changeover valve opening located in a further subsequent fourth row. At least one connection for a wheel pressure sensor is positioned in a third row between the second and fourth rows. At least one connection for a master cylinder pressure sensor is positioned in a fifth row following the fourth row.

First claim

The invention claimed is:

1. A pump housing of a motor vehicle hydraulic assembly, comprising:
at least two inlet valve openings disposed in a first row, each of the at least two inlet valve openings being configured to receive an inlet valve;
at least two outlet valve openings disposed in a following second row, each of the at least two outlet valve openings being configured to receive an outlet valve;
at least one wheel pressure sensor connection disposed in a further following third row, each of the at least one wheel pressure sensor connections being configured to receive a wheel pressure sensor;
at least one high pressure switching valve opening disposed in a further following fourth row, each of the at least one high pressure switching valve openings being configured to receive a high pressure switching valve;
at least one changeover valve opening disposed in the further following fourth row, each of the at least one changeover valve openings being configured to receive a changeover valve; and
a pump element opening configured to receive a pump element, the pump element opening being defined in a first side surface of the pump housing,
a first line extends from one of the at least two outlet valve openings to a wheel brake cylinder opening,
the wheel pressure sensor connection is connected to the first line via a first line connection, and
wherein the first line connection is defined by a first transverse bore formed in the first side surface transverse to the first line.

2. A pump housing of a motor vehicle hydraulic assembly, comprising:
at least two inlet valve openings disposed in a first row, each of the at least two inlet valve openings being configured to receive an inlet valve;
at least two outlet valve openings disposed in a following second row, each of the at least two outlet valve openings being configured to receive an outlet valve;
at least one wheel pressure sensor connection disposed in a further following third row, each of the at least one wheel pressure sensor connections being configured to receive a wheel pressure sensor;
at least one high pressure switching valve opening disposed in a further following fourth row, each of the at least one high pressure switching valve openings being configured to receive a high pressure switching valve;
at least one changeover valve opening disposed in the further following fourth row, each of the at least one changeover valve openings being configured to receive a changeover valve; and
a master cylinder-pressure sensor connection configured to receive a master cylinder pressure sensor, the master cylinder-pressure sensor connection being disposed in a further following fifth row in such a way that no portion of the master cylinder pressure sensor connection intersects a plane defined normal to an outer surface of the pump housing in which the at least one changeover valve opening is defined and extending centrally through the at least one changeover valve opening.

3. The pump housing as claimed in claim 2 , wherein:
a second line extends from a master cylinder connection to one of the at least one high pressure switching valve openings and to one of the at least one changeover valve openings; and
the master cylinder pressure sensor connection is connected to the second line via a second line connection.

4. The pump housing as claimed in claim 3 , further comprising:
a pump element opening configured to receive a pump element, the pump element opening being defined in a first side surface of the pump housing,
wherein the second line connection is defined by a second transverse bore formed in the first side surface transverse to the second line.

5. The pump housing as claimed in claim 2 , wherein:
a first line extends from one of the at least two outlet valve openings to a wheel brake cylinder opening; and
the wheel pressure sensor connection is connected to the first line via a first line connection.

6. The pump housing as claimed in claim 2 , wherein two changeover valve openings of the at least one changeover valve opening are disposed between two high pressure switching valve openings of the at least one high pressure switching valve opening.

7. A motor vehicle brake system, comprising:
a pump housing that includes:
at least two inlet valve openings disposed in a first row;
at least two outlet valve openings disposed in a following second row;
at least one wheel pressure sensor connection disposed in a further following third row;
at least one high pressure switching valve opening disposed in a further following fourth row;
at least one changeover valve opening disposed in the further following fourth row;

at least two inlet valves, each of the at least two inlet valves being received in a corresponding one of the at least two inlet valve openings;
at least two outlet valves, each of the at least two outlet valve openings being received in a corresponding one of the at least two outlet valve openings;
at least one wheel pressure sensor, each of the at least one wheel pressure sensors being hydraulically connected to a corresponding one of the at least one wheel pressure sensor connections;
at least one high pressure switching valve, each of the at least one high pressure switching valves being received in a corresponding one of the at least one high pressure switching valve openings;
at least one changeover valve, each of the at least one changeover valves being received in a corresponding one of the at least one changeover valve openings; and
a pump element,
wherein:
a first line in the pump housing extends from one of the at least two outlet valve openings to a wheel brake cylinder opening configured to connect to a wheel brake cylinder of the brake system,
the wheel pressure sensor connection is connected to the first line via a first line connection in the pump housing,
a first side surface of the pump housing defines a pump element opening in which the pump element is received, and
the first line connection is defined by a first transverse bore formed in the first side surface.

8. A motor vehicle brake system, comprising:
a pump housing that includes:
at least two inlet valve openings disposed in a first row;
at least two outlet valve openings disposed in a following second row;
at least one wheel pressure sensor connection disposed in a further following third row;
at least one high pressure switching valve opening disposed in a further following fourth row;
at least one changeover valve opening disposed in the further following fourth row; and
a master cylinder pressure sensor connection disposed in a further following fifth row in such a way that no portion of the master cylinder pressure sensor connection intersects a plane defined normal to an outer surface of the pump housing in which the at least one changeover valve opening is defined and extending centrally through the at least one changeover valve opening;

at least two inlet valves, each of the at least two inlet valves being received in a corresponding one of the at least two inlet valve openings;
at least two outlet valves, each of the at least two outlet valve openings being received in a corresponding one of the at least two outlet valve openings;
