Die Aufgabe ist auch mit einem Pumpengehäuse eines Kraftfahrzeug- Hydroaggregats gelöst, insbesondere der oben genannten Art, mit mindestens einer Umschaltventilöffnung und mindestens einer Pumpenelementöffnung, die mit einer Einlassventilöffnung über eine zweite Verbindungsleitung verbunden ist, bei dem die Umschaltventilöffnung mit der zweiten Verbindungsleitung über eine zweite Bohrung, insbesondere eine zweite Sackbohrung, verbunden ist. Die zweite Bohrung schafft eine fluidleitende Verbindung zwischen der Umschaltventilöffnung und der Pumpenelementöffnung mittels eines Umwegs über die Einlassventilöffnung und nutzt dabei eine ohnehin vorhandene Leitungsverbindung zwischen der Einlassventilöffnung und der Pumpenelementöffnung. Es ist daher mit dieser Vorgehensweise für die Ankopplung der Umschaltventilöffnung an die Pumpenelementöffnung nur eine kurze Leitungstrecke zusätzlich auszubilden. The object is also achieved with a pump housing of a motor vehicle hydraulic unit, in particular of the aforementioned type, with at least one Umschaltventilöffnung and at least one pump element opening, which is connected to an inlet valve opening via a second connecting line, wherein the Umschaltventilöffnung with the second connecting line via a second Bore, in particular a second blind bore, is connected. The second bore creates a fluid-conducting connection between the changeover valve opening and the pump element opening by means of a detour via the inlet valve opening and thereby utilizes an already existing line connection between the inlet valve opening and the pump element opening. It is therefore with this approach for the coupling of the Umschaltventilöffnung to the pump element opening only a short line section additionally train.
Ferner ist die Aufgabe mit einem Pumpengehäuse eines Kraftfahrzeug- Hydroaggregats gelöst, insbesondere der oben genannten Art, mit mindestens einer Speicheröffnung und mindestens zwei Auslassventilöffnungen, die über ei- ne dritte Verbindungsleitung miteinander verbunden sind, bei dem die Speicheröffnung mit der dritten Verbindungsleitung über eine dritte Bohrung, insbesondere eine dritte Sackbohrung, verbunden ist. Mit dieser Vorgehensweise kann die Speicheröffnung über eine wiederum besonders kurze Bohrung mit beiden Auslassventilöffnungen fluidleitend verbunden werden. Furthermore, the object is achieved with a pump housing of a motor vehicle hydraulic unit, in particular of the abovementioned type, with at least one storage opening and at least two outlet valve openings which are located above one another. ne third connecting line are connected to each other, in which the storage opening with the third connecting line via a third bore, in particular a third blind bore, is connected. With this procedure, the storage opening can be fluid-conductively connected to both outlet valve openings via a particularly short bore.
An der Speicheröffnung ist vorteilhaft ein Speicher mittels Schweißen angekoppelt, wodurch ebenfalls eine besonders kostengünstig herzustellende, gut vorzumontierende und insgesamt sehr bauraumsparende Lösung geschaffen ist. At the storage opening, a memory is advantageously coupled by means of welding, which also creates a particularly inexpensive to produce, well vorzumontierende and overall very space-saving solution.
Schließlich ist die Aufgabe auch durch Verwendung eines derartigen erfindungsgemäßen Pumpengehäuses an einem Kraftfahrzeug-Hydroaggregat gelöst.. Finally, the object is also achieved by using such a pump housing according to the invention on a motor vehicle hydraulic unit.

The master cylinder 16 is connected to two largely identical brake circuits 18 and 20, which are essentially in a common pump housing 22 (see FIG 2 ff.) Are shown. Hereinafter, only one of these brake circuits, namely the brake circuit 18, explained in more detail.
Für den Bremskreis 18 führt eine Leitung 24 vom Hauptzylinder 16 zu einem Hochdruckschaltventil 26 und einem Umschaltventil 28. An der Leitung 24 ist fer- ner ein Drucksensor 30 angeschlossen. Vom Hochdruckschaltventil 26 führt eineFor the brake circuit 18, a line 24 leads from the master cylinder 16 to a high-pressure switching valve 26 and a switching valve 28. A pressure sensor 30 is also connected to the line 24. From the high pressure switching valve 26 performs a

Vom Umschaltventil 28 führt eine Leitung 38 zur Druckseite des Pumpenelements 34 sowie zu einem ersten Einlassventil 40 und einem zweiten Einlassventil 42. Von dem Rückschlagventil 36 führt eine Leitung 44 zu einem ersten Auslassventil 46 und einem zweiten Auslassventil 48. An der Leitung 44 ist ferner ein Speicher 50 angeschlossen. Von dem ersten Einlassventil 40 führt eine Leitung 52 zu einem ersten Radbremszylinder 54 sowie zum ersten Auslassventil 46 und von dem zweiten Einlassventil 42 führt eine Leitung 56 zu einem zweiten Radbremszylinder 58 sowie zum zweiten Auslassventil 48. From line 32 leads a line 38 to the pressure side of the pump element 34 and to a first inlet valve 40 and a second inlet valve 42. From the check valve 36, a line 44 leads to a first outlet valve 46th and a second exhaust valve 48. On the line 44, a memory 50 is also connected. A line 52 leads from the first inlet valve 40 to a first wheel brake cylinder 54 and to the first outlet valve 46 and from the second inlet valve 42 a line 56 leads to a second wheel brake cylinder 58 and to the second outlet valve 48.
In den Fig. 2 bis 4 ist ein Pumpengehäuse 22 gemäß dem Stand der Technik dargestellt, welches im Wesentlichen aus einem Aluminiumblock gebildet ist, in dem mittels Bohren bzw. Fräsen Öffnungen ausgebildet sind. So befinden sich an der Oberseite 60 des Aluminiumblocks vier Radbremszylinderöffnungen 62 zum Aufnehmen der oben genannten Anschlüsse für die Radbremszylinder 54 sowie 58 und an der Vorderseite 64 des Aluminiumblocks in einer obersten Zeile vier Einlassventilöffnungen 66 zum Aufnehmen der oben genannten Einlassventile 40 sowie 42. Unter den Einlassventilöffnungen 66 befinden sich in einer zweiten Zeile vier Auslassventilöffnungen 68 zum Aufnehmen der oben genannten Auslassventile 46 sowie 48. Unter den Auslassventilöffnungen 68 sind in einer dritten Zeile dann zwei Hochdruckschaltventilöffnungen 70 und in einer darunter liegenden vierten Zeile außen zwei Umschaltventilöffnungen 72 sowie mittig ein Drucksensoranschluss 74 zum Aufnehmen eines oben genannten Hochdruckschaltventils 26, eines Umschaltventils 28 bzw. des Drucksensors 30 angeord- net. An der Unterseite 76 des Aluminiumblocks befinden sich zwei Speicheröffnungen 78 zum Aufnehmen eines oben genannten Speichers 50 und an der Rückseite 80 zwei Hauptzylinderanschlüsse 82. Zwischen einer Speicheröffnung 78 und einem zugehörigen Hauptzylinderanschluss 82 erstreckt sich die oben genannte Leitung 24 in Form einer in die Speicheröffnung 78 eingebrachten Längsbohrung2 to 4, a pump housing 22 is shown according to the prior art, which is essentially formed of an aluminum block in which openings are formed by drilling or milling. Thus, at the top 60 of the aluminum block, four wheel-brake cylinder ports 62 for receiving the above-mentioned ports for the wheel brake cylinders 54 and 58 and at the front 64 of the aluminum block in an uppermost row have four intake valve ports 66 for receiving the above intake valves 40 and 42 Intake valve ports 66 are located in a second row of four exhaust valve ports 68 for receiving the above exhaust valves 46 and 48. Below the exhaust valve ports 68 are in a third row then two high pressure switching valve ports 70 and in a lower fourth row outside two switching valve ports 72 and center a pressure sensor port 74 for receiving an above-mentioned high-pressure switching valve 26, a switching valve 28 and the pressure sensor 30, respectively. On the underside 76 of the aluminum block there are two storage openings 78 for receiving an above-mentioned storage 50 and at the rear 80 two master cylinder connections 82. Between a storage opening 78 and an associated master cylinder connection 82, the above-mentioned conduit 24 extends in the form of a storage opening 78 introduced longitudinal bore
84. Zu dieser Längsbohrung 84 ist von der linken Seite 86 des Aluminiumblocks aus eine Querbohrung 88 ausgebildet, welche die Längsbohrung 84 mit dem mittig angeordneten Drucksensoranschluss 74 verbindet. Die Querbohrung 88 erstreckt sich dabei durch eine Umschaltventilöffnung 72, so dass auch diese an die Längsbohrung 84 angeschlossen ist. In die Längsbohrung 84 mündet ferner auch eine nach außen gerichtet offene Hochdruckschaltventilöffnung 70. 84. To this longitudinal bore 84, a transverse bore 88 is formed from the left side 86 of the aluminum block, which connects the longitudinal bore 84 with the centrally arranged pressure sensor connection 74. The transverse bore 88 extends through a switching valve opening 72, so that this is also connected to the longitudinal bore 84. In the longitudinal bore 84 also opens an outwardly open high-pressure switching valve opening 70th
Zwei Auslassventilöffnungen 68 sind über eine Querbohrung 90 und eine Längsbohrung 91 ebenfalls mit einer zugehörigen Speicheröffnung 78 verbunden, um die oben genannte Leitung 44 zu bilden. Eine mit der Längsbohrung 84 verbundene Hochdruckschaltventilöffnung 70 ist ferner mit einer Pumpenelementöff- nung 92 verbunden, die von der Seite aus in den Aluminiumblock hinein ausgebildet ist. Ferner ist die Pumpenelementöffnung 92 mit der Speicheröffnung 78 über eine Längsbohrung 94, in der das Rückschlagventil 36 am Übergang von der Längsbohrung 94 in die Speicheröffnung 78 angeordnet ist, verbunden, um die oben genannte Leitung 32 zu bilden. Two outlet valve ports 68 are also connected via a transverse bore 90 and a longitudinal bore 91 to an associated reservoir orifice 78 to form the above-mentioned conduit 44. A high-pressure switching valve opening 70 connected to the longitudinal bore 84 is further connected to a pump element opening 92, which is formed from the side into the aluminum block. Furthermore, the pump element opening 92 is connected to the storage opening 78 via a longitudinal bore 94, in which the check valve 36 is arranged at the transition from the longitudinal bore 94 into the storage opening 78, to form the above-mentioned line 32.
Die an der Querbohrung 88 angeschlossene Umschaltventilöffnung 72 ist ferner mittels einer Längsbohrung 96 mit der Pumpenelementöffnung 92 und mittels ei- ner weiteren Querbohrung 98 mit zwei Einlassventilöffnungen 66 verbunden, um die oben genannte Leitung 38 zu bilden. Die oben genannten Leitungen 52 und 56 sind schließlich mittels Längsbohrungen 100 bzw. 102 ausgebildet, die jeweils von einer der Radbremszylinderöffnungen 62 zu einer zugehörigen Einlassventilöffnung 66 sowie einer Auslassventilöffnung 68 geführt sind. The change-over valve opening 72 connected to the transverse bore 88 is further connected by means of a longitudinal bore 96 to the pump element opening 92 and by means of a further transverse bore 98 with two inlet valve openings 66 to form the above-mentioned line 38. The above-mentioned lines 52 and 56 are finally formed by means of longitudinal bores 100 and 102, which are each guided by one of the wheel brake cylinder openings 62 to an associated inlet valve opening 66 and an outlet valve opening 68.
An der Rückseite des derartigen Aluminiumblocks befindet sich noch ein Motor- anschluss mit einem zugehörigen Antriebsmotor 104 für die in den Pumpenele- mentöffnungen 92 anzuordnenden Pumpenelemente 34. In den Fig. 5 bis 1 1 ist ein erfindungsgemäßes Pumpengehäuse 22 veranschaulicht, bei dem ebenfalls vier Radbremszylinderöffnungen 62, vier Einlassventilöff- nungen 66, vier Auslassventilöffnungen 68, zwei Hochdruckschaltventilöffnungen 70, zwei Umschaltventilöffnungen 72, ein Drucksensoranschluss 74, zwei Speicheröffnungen 78, zwei Hauptzylinderanschlüsse 82, zwei Pumpenelementöff- nungen 92 und ein Motoranschluss mit einem Antriebsmotor 104 vorgesehen sind. Allerdings sind bei der erfindungsgemäßen Gestaltung des Pumpengehäuses 22 die Öffnungen und die zugehörigen Bohrungen anders angeordnet und ausgeführt als gemäß dem Stand der Technik. On the rear side of such aluminum block there is still a motor connection with an associated drive motor 104 for the pump element openings 92 to be arranged pump elements 34. In FIGS. 5 to 1 1 an inventive pump housing 22 is illustrated, in which also four wheel cylinder openings 62, four intake valve open 66, four exhaust valve ports 68, two high pressure switching valve ports 70, two switching valve ports 72, a pressure sensor port 74, two reservoir ports 78, two master cylinder ports 82, two pump element ports 92, and a motor port with a drive motor 104. However, in the design of the pump housing 22 according to the invention, the openings and the associated bores are arranged and designed differently than in the prior art.
So sind bei dem erfindungsgemäßen Pumpengehäuse 22 gemäß den Fig. 5 und 7 an dessen Vorderseite 64 die Einlassventilöffnungen 66 in einer ersten Zeile bzw. Reihe, die Auslassventilöffnungen 68 in einer nachfolgenden zweiten Zeile bzw. Reihe, der Drucksensoranschluss 74 in einer weiter nachfolgenden dritten Zeile und die beiden Hochdruckschaltventilöffnungen 70 sowie die beiden Umschaltventilöffnungen 72 in einer weiter nachfolgenden vierten Zeile bzw. Reihe angeordnet. Der Drucksensoranschluss 74 mündet dabei unmittelbar in die ebenfalls vorgesehene Längsbohrung 84, so dass auf eine Querbohrung 88 wie bei der Ausführung gemäß Fig. 2 bis 4 verzichtet werden kann. Thus, in the pump housing 22 according to the invention as shown in FIGS. 5 and 7 on the front side 64, the inlet valve openings 66 are in a first row, the outlet valve openings 68 in a subsequent second row, the pressure sensor connection 74 in a third row following and the two high-pressure switching valve openings 70 as well as the two switching-valve openings 72 are arranged in a further following fourth row or row. The pressure sensor port 74 discharges directly into the likewise provided longitudinal bore 84, so that it is possible to dispense with a transverse bore 88 as in the embodiment according to FIGS. 2 to 4.
Die beiden Umschaltventilöffnungen 72 sind zwischen den beiden Hochdruck- schaltventilöffnungen 70 angeordnet. Die einzelne Umschaltventilöffnung 72 und die einzelne Hochdruckschaltventilöffnung 70 sind mit der Längsbohrung 84 mittels je eines Hinterstichs 106 bzw. 108 verbunden. Diese Gestaltung erübrigt es, dass zum Anschließen der Umschaltventilöffnung 72 eigens eine Querbohrung 88 wie bei der Ausführung gemäß Fig. 2 bis 4 auszubilden wäre. The two switching valve openings 72 are arranged between the two high-pressure switching valve openings 70. The individual switching valve opening 72 and the individual high-pressure switching valve opening 70 are connected to the longitudinal bore 84 by means of an undercut 106 and 108, respectively. This design makes it unnecessary for a separate bore 88 to be formed as in the embodiment according to FIGS. 2 to 4 for connecting the switching valve opening 72.
Wie in Fig. 8 gesondert veranschaulicht ist, ist die Leitung 32 zwischen einer Pumpenelementöffnung 92, einer zugehörigen Speicheröffnung 78 und einer Hochdruckschaltventilöffnung 70 mittels der ebenfalls ausgebildeten Längsbohrung 94 und einer als Sackbohrung gestalteten Querbohrung 1 10 gestaltet. Die Querbohrung 1 10 kann dabei besonders kurz gestaltet sein. Dabei ist die Längsbohrung 94 die Aufnahmebohrung für das Rückschlagventil 36. As is shown separately in FIG. 8, the line 32 is designed between a pump element opening 92, an associated storage opening 78 and a high-pressure switching valve opening 70 by means of the likewise formed longitudinal bore 94 and a transverse bore 1 10 designed as a blind bore. The transverse bore 1 10 can be designed to be particularly short. In this case, the longitudinal bore 94 is the receiving bore for the check valve 36th
Die Fig. 9 veranschaulicht ein weiteres Detail der erfindungsgemäßen Gestaltung, gemäß der die oben genannte Leitung 38 zwischen einer Umschaltventil- Öffnung 72, einer zugehörigen Pumpenelementöffnung 92 und einer zugehörigenFig. 9 illustrates a further detail of the inventive design, according to which the above-mentioned line 38 between a Umschaltventil- opening 72, an associated pump element opening 92 and an associated
Einlassventilöffnung 66 mittels einer zusätzlichen, ebenfalls als Sackbohrung gestalteten Längsbohrung 1 12 gebildet ist, die von der Umschaltventilöffnung 72 hinten an der Pumpenelementöffnung 92 vorbei bis zur Querbohrung 98 führt. Die Längsbohrung 112 schafft damit eine fluidleitende Verbindung von der Umschaltventilöffnung 72 zunächst bis zur Querbohrung 98, von wo aus dann die ebenfalls vorgesehene (jetzt aber kürzer gestaltete) Längsbohrung 96 zur Pumpenelementöffnung 92 führt. Inlet valve opening 66 by means of an additional, also as a blind hole shaped longitudinal bore 1 12 is formed, which leads from the Umschaltventilöffnung 72 rear of the pump element opening 92 over to the transverse bore 98. The longitudinal bore 112 thus creates a fluid-conducting connection from the Umschaltventilöffnung 72 first to the transverse bore 98, from where then also provided (but now shorter designed) longitudinal bore 96 leads to the pump element opening 92.
In der Fig. 10 ist in Bezug auf die Rückseite 80 des Pumpengehäuses 22 gemäß der Erfindung veranschaulicht, dass dort die Speicheröffnung 78 und zwei Aus- lassventilöffnungen 68 über eine ebenfalls ausgebildete Querbohrung 90 sowie eine von der Speicheröffnung 78 ebenfalls ausgehende Längsbohrung 91 verbunden sind. Zwischen der Längsbohrung 91 und er Querbohrung 90 ist dazu eine weitere Querbohrung 1 14 als kurze Sackbohrung ausgebildet. Die Fig. 11 veranschaulicht schließlich, dass in der Speicheröffnung 78 mit dem dort in der Längsbohrung 94 eingesetzten Rückschlagventil 36 eine zylindrische Speicheranordnung 116 eingesetzt ist. Die Speicheranordnung 116 ist mittels einer umlaufenden Schweißnaht 1 18 an der Unterseite 76 des Pumpengehäuses 22 angeschweißt. Nachfolgend ist auf die Speicheranordnung 116 ein Federele- ment 120 aufgeschoben worden, an dem ein Halter 122 zum Befestigen des10 illustrates with respect to the rear side 80 of the pump housing 22 according to the invention that there the storage opening 78 and two outlet valve openings 68 are connected via a likewise formed transverse bore 90 and also from the storage opening 78 also extending longitudinal bore 91. Between the longitudinal bore 91 and he transverse bore 90 is a further transverse bore 1 14 formed as a short blind hole. Finally, FIG. 11 illustrates that a cylindrical storage arrangement 116 is inserted in the storage opening 78 with the check valve 36 inserted therein in the longitudinal bore 94. The storage arrangement 116 is welded by means of a peripheral weld 1 18 on the underside 76 of the pump housing 22. Subsequently, a spring element 120 has been pushed onto the storage arrangement 116, on which a holder 122 for fastening the
Pumpengehäuses 22 an einem weiter nicht dargestellten Fahrzeug angeordnet ist. Pump housing 22 is arranged on a vehicle, not shown.
